Throttle Position Sensor

The TPS is sensitive to heat, moisture and vibration leading to the failure of some units. The sensor is a sealed unit and cannot be repaired only replaced. A TPS may fail gradually leading to a number of symptoms which can include one or more of the following: -

• Poor idle control. The TPS is used by the ECU to determine if the throttle is closed and the car should be using the Idle Air Control Valve exclusively for idle control. A fault TPS sensor can confuse the ECU causing the idle to be erratic or "hunting".

• High Idle Speed. The TPS may report faulty values causing the engine idle speed to be increased above normal. This is normally found in conjunction with a slow engine return to idle speed symptom.

• Slow engine return to idle. A failing TPS can report the minimum throttle position values incorrectly which can stop the engine entering idle mode when the throttle is closed. Normally when the throttle is closed the engine fuel injectors will be deactivated until a defined engine RPM speed is reached and the engine brought smoothly to idle speed. When failing a TPS will not report the throttle closed and fueling will continue causing the engine to return to idle very slowly.

• Engine Hesitation on Throttle Application. The TPS is also used by the ECU to determine if the driver has applied the throttle quicker than the Manifold Air Pressure sensor can read. The fueling is adjusted acordingly to cope with the sudden increase in air volume, however a faulty sensor can cause the ECU to ignore this data and the engine will "hesitate" when applying the throttle. In extreme cases with the engine at idle, a sudden application of full throttle can stall the engine.

• Engine Misfire. A fault TPS can report values outside the deined acceptable range causing the ECU to incorrectly fuel the engine. This is noticable as a slight misfire and can trigger the misfire detection software and/or Malfunction Indicator Lamp (MIL) light on the dashboard. Extreme cases can cause excessing misfires resulting in one or more cylinders being shut down to prevent engine and catalytic converter damage.

In all cases a manual recalibration of the TPS may resolve the issues at least on a temporary basis. To recalibrate the TPS: -

1. With the engine off, insert the key and turn the ignition to position 2 (On) without starting the engine.
2. For MEMS-equipped cars (S1)Or S2 Rover engined cars, quickly but steadily press and release the accelerator pedal 5 times for TPS calibration, using all of the throttle travel as practicable. It is better to do this from the engine bay, using the cam on the throttle body, as this ensures you get 0-100% operation of the throttle, and correct calibration, If your throttle cable or mech does not give 100% throttle, calibration will be out. And potentially you will be wasting your time. This will trigger the ECU into the closed-throttle reference learn algorithm, which has it looking for the lowest measured static throttle position (the closed position). The throttle position calibration is a fixed definition from this point.
3. Turn the ignition off, remove the key and wait for the ECU to power down (about 30-40s).
4. Start car as normal.

It's often sold and replaced as part of the throttle body itself however can be replaced separately.

What is a Throttle? (with pictures) - mobile wiseGEEK

A car’s throttle is essentially what controls how fast the engine goes, and therefore how fast the car goes. The throttle is usually a butterfly valve assembly on the intake manifold. and is connected to the accelerator. or gas pedal, via the throttle linkage. This linkage enables you to control the engine’s throttle by how far you move the gas pedal — the further down you press the gas pedal, the more the throttle opens.

Many people hold the misconception that the purpose of the throttle is to control the amount of fuel going into the engine. In fact, it is the exact opposite: the throttle controls the amount of air that goes into the engine.

An internal combustion engine runs on the force of exploding fuel and air. However, to generate the proper explosion in the combustion chambers, there needs to be a very specific mixture of vaporized fuel and oxygen. Therefore, in an internal combustion engine, there are several systems in place to regulate the air/fuel ratio.

In a carbureted car, the carburetor uses very simple principles of vacuum to maintain the correct air/fuel ratio. In a fuel injected car, on the other hand, the air flow meter. oxygen sensor. and the computer that run the electronic fuel injection all work together to ensure that the engine gets the right amount of both air and fuel. There are two different kinds of electronic fuel injection: throttle body injection, which works more like a computerized version of a carburetor, and multiport injection, which features a separate fuel injector for each cylinder.

Whether the car is carbureted or fuel injected, when the throttle opens, more air rushes into the engine. At the same time, the intake and fuel systems compensate by adding more fuel to the mixture. In other words, the throttle directly controls the amount of air that enters the combustion chambers, which indirectly affects the amount of fuel that enters the chambers.

Throttle body - The Full Wiki

(Redirected to Throttle article)

In a petrol (gasoline) internal combustion engine. the throttle is a valve that directly regulates the amount of air entering the engine, indirectly controlling the fuel burned on each cycle due to the fuel-injector or carburetor maintaining a relatively constant fuel/air ratio. In a motor vehicle the control used by the driver to regulate power is sometimes called the throttle pedal or accelerator.

The throttle is typically a butterfly valve. In a fuel-injected engine, the throttle valve is housed in the throttle body. In a carbureted engine, it is found in the carburetor.

When a throttle is wide open. the intake manifold is usually at ambient atmospheric pressure. When the throttle is partially closed, a manifold vacuum develops as the intake drops below ambient pressure.

Usually the throttle valve is mechanically linked with the throttle pedal or lever. In vehicles with electronic throttle control. the throttle valve is electronically controlled, which allows the ECU greater possibilities in reducing air emissions.

In a reciprocating-engine aircraft, the throttle control is usually a hand-operated lever or knob. It controls the engine power, which may or may not reflect in a change of RPM, depending on the propeller installation (fixed-pitch or constant speed ). [ 1 ]

Diesel engines do not need to control air volumes. Thus they lack a butterfly valve in the intake tract, and do not have a throttle (although recent developments in Exhaust Gas Recirculation have introduced throttle-style designs [ 2 ] ). They instead regulate engine power by directly controlling the quantity of fuel injected into the cylinder just before top dead centre (TDC) of the compression stroke.

The components of a typical throttle body

In fuel injected engines. the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold. and it is usually attached to, or near, the mass airflow sensor .

Image of BMW S65 from the e92 BMW M3 showing eight individual throttle bodies

Many cars have a single throttle body, however more than one may be used, chained together by linkages, to improve throttle response. At the extreme, high performance cars, such as the BMW M1. and high performance motorcycles, like the Suzuki Hayabusa. have a separate throttle body for each cylinder. These are often referred to as "individual throttle bodies", or ITBs.

A throttle body is somewhat analogous to the carburetor in a non-injected engine. Carburetors combine the functionality of the throttle body and the fuel injectors into one, that is, to modulate the amount of air flow, and to combine air and fuel together. Cars with throttle body injection (called TBI by General Motors and CFI by Ford ) locate the fuel injectors in the throttle body, thereby allowing an older engine to be converted from carburetor to fuel injection without significantly altering the engine design.

Regulation of the throttle is also a mechanism for controlling engine exhaust emissions. In many modern internal combustion engines an electronic throttle is used, eliminating the older accelerator cable. [ 3 ]

Throttle application via the accelerator pedal also results in increased sound emission from the engine. At lower operating speeds this component of vehicle noise is prominent, contrasted with higher operating speeds, for which aerodynamic and tire noise are more significant. [ 4 ]

Most engines have some kind of throttle control, though the particular way that power is regulated is often different.

Liquid rockets are throttled by controlling the pumps which send liquid fuel and oxidizer to the combustion chamber. Solid rockets are not controllable once the solid fuel is ignited. Hybrid rockets. like the one used in Space Ship One. use solid fuel and liquid oxidizer, thus throttling is possible through the oxygen pumps, like in a full liquid rocket motor.

In a jet engine. engine output is also directly controlled by changing the amount of fuel flowing into the combustion chamber, usually with an autothrottle. In some instances, a "throttle" is known as a "thrust lever " (as in most Airbus and Boeing aircraft ). This is chiefly due to the fact that "throttle" is associated with traditional gasoline engines. [ 5 ]

Throttle is a

posted by ymaurer 5 years ago Why is the "Firefox Throttle" addon not available anymore and is there a replacement?

I need to be able to dynamically slow down (throttle) the speed with which my firefox downloads content. There are thousands of google links to an extension that seems to do exactly what I want: https://addons.mozilla.org/en-US/firefox/addon/5917/ However this is now a dead link. Why?

Is there a replacement?

The authors of the add-on may have removed it from the add-ons site or discontinued the add-on. You can try asking them at http://www.uselessapplications.com/en/Contact.aspx

You can still try to find it on software download websites (use google). I'm still using this add-on to limit my downloads when watching videos online (4 computers at home and only 2Mbits/s Internet connection). Just wondering if there is another easy way to limit down speed? Just want to start using Firefox 4.0 but latest version is not working with new Gecko :( Hope that soon someone will make a new similar add-on (tried to modify it to be compatible with 4.0 but just can't fix and recompile *.dll files)

The file is still on the FTP server:

Thanks for the help guys!

That file can disappear at anytime, so be sure to save it on your computer.

The link: http://www.uselessapplications.com/en/Application/FirefoxThrottle.aspx is DEAD and when you go to their site at: http://www.uselessapplications.com/en/ it does not list any current add-on's. Sure hope they are still doing FireFox add-on's.

If anyone knows about ANY other FireFox add-on that does the same thing PLEASE post it here.

Did you try my above posted link to the XPI file?

It looks that the file firefox_throttle-1.1.6-fx-win.xpi in still on the Add-ons FTP server.

Hi cor-el,

Thanks for the link. I have downloaded and saved it.

My hope is that the people at www.uselessapplications.com will take a second look at this application and even make it a "4-pay" item.

I would most likely PAY to have it available for all future versions of FireFox.

I have looked at some other programs ( not add-on's ) and they are mostly system wide applications and not nearly as easy to use as FireFox Throttle.

I have left a message on their site twice with no response as yet.

IT's BACK.

However the download is version 1.1.5! and version 1.1.6 is out there.

I will contact them to let them know about this forum. and ask about version numbers and FireFox 4. support.

^ that version of Firefox Throttle is for Firefox 3.6. The install.rdf has 3.6 as the maxVersion and that file was last modified in Jan 2010, which makes it over a year old and it coincides with the release of Firefox 3.6.

I have been in contact with the folks there about a time line for a version that will work with FireFox ver: 4.x and their response is:

That's ok. I'm really swamped with other stuff at the moment. Best bet is end of April-mid May.

Hope this estimate holds,

Though it's not my app, I've put it on GitHub. I need it. https://github.com/hkirsman/Firefox-Throttle

I changed the version limiter to Firefox 5.*

It installs but menu is a bit weird, it's missing active/disable button on the toolbar and when trying to save options, it says "TypeError: this.watcherservice is undefined"

Cool plugin!

I think it's version 1.1 but I head there was 1.1.6. Maby somebody could send it? Maby it works in Firefox 4?

My email is hkirsman@gmail.com

this version can not support FF 4.0.1 Hope someone can post a latest version supporting 4.0.1.

This plug-in is the reason I haven't updated to FF 4, and I won't update until this works with it  :p

Here is a version modified to work with all versions (well, up to 9.xx)

Hey BCN, your patch didn't work for me. I run it on FF 7. Did you just play with the compatibility requirements in install.rdf to trick the compatibility checker or did you actually change the architecture of the plugin so that it truly becomes compatible with FF4+?

Well, either way, I have an alternative solution to propose. It works very nicely for me. Actually, it's ideal. It involves getting the best of both worlds: being able to simultaneously run the latest version of Firefox for (unthrottled) browsing and a legacy 3.6x version for my big (throttled) downloads.

Solution 0.6.9.23.11 (DIY Version of my Solution ):

Setting Up a Separate Portable Firefox 3.6.x that runs independently of and simultaneously to your latest version of Firefox

It's a portable app, meaning that it's got all it's profiles and preference and application files in the same directory. It won't compete with your current installation of Firefox, has it's own separate extension folder etc.

Get Firefox Throttle 1.1.6 http://firefox-throttle.en.softonic.com/ (I couldn't find it in the official mozilla site)

It will be flagged as incompatible with even that old version of firefox (but it isn't). You just need to turn off compatibility checking. You can do that with this extension:

If you have Bookmarks you want to port to the portable (bad pun intend), backup them up to bookmarks.json file on your desktop and import them to the portable version. You can export/import more stuff using FEBE addon but that's a whole world of headaches if you don't your doing.

Many of your extensions favourites extensions will no longer work on FFox 3.6.x but if, in that same addon's page, you look around until you find a link to previous versions of the addon, you will notice that the compatibility info is right below the version numbers. Just download and install the latest version that is compatible with you 3.6.x.

Voila mon ami! Your FFox 3.6 portable has just become your own private Download Mule whom you can throttle to your hearts content (ever throttle a real Mule. I wouldn't try it, personally. ) Do your regular browsing in another (unthrottled) browser and do your big downloads in the Mule.

If you want to keep using your brand spanking new Firefox for other types of browsing while using this portable Mule edition for the downloads, just add -p -no-remote to the shortcut leading to your Firefox Portable Mule edition.

For example, my taskbar shortcut to my Firefox Portable is:

""C:\Program Files (x86)\FirefoxPortableLegacy36\FirefoxPortable.exe"

I just changed it to:

"C:\Program Files (x86)\FirefoxPortableLegacy36\FirefoxPortable.exe" -p -no-remote

This will make it occupy it's own independent instance and I can use the both my Firefox Nightly and the Firefox Portable editions at the same time (each one, using a different profile ie. extensions, cookies, password, cache etc).

If you're on Linux, you can just run this on Wine and set the Windows Version to Windows 2000 in the Wine config,

If you want to get rid of the Portable Apps splash screen, click here:

Solution 0.6.9.23.11 (Non-DIY Version of my Solution):

Download my preconfigured but SWAGGED-THE-HECK-UP PortableFirefox 3.6

Having realized that some of you may find the above to be daunting. I took my own customize firefox portable, took out all my data and compressed the folder (it's portable, so it'll run as soon as you unzip it).

A screenshot is attached below. I know it looks like I'm running FFox 4+ on there but that's because I've enhanced 3.6.24.

Here is the download link:

Don't forget to modify your Start/Taskbar shortcuts:

"C:\wherever you decide to put it\FirefoxPortableLegacy36-Swagged-UP!\FirefoxPortable.exe"

I just changed it to:

"C:\wherever you decide to put it\FirefoxPortableLegacy36-Swagged-UP!\FirefoxPortable.exe" -p -no-remote

Any news? I spent a little time to check the extension. It is not possible to run it under FF4+ without recompiling, because there is a change in the API of Firefox. The author needs to compile a new version of FFThrottle.dll May be some one could write to him again, maybe he could share the source.

@momashi69, I like your method and use it myself, but Firefox 3.6 is scheduled to be "end-of-lifed" on April 24, 2012:

One could continue using Portable 3.6 but would be missing out on security updates.

Edit: DownThemAll! (2.0.13 as of this writing) supports download throttling for individual files and works in Firefox 4+ (10.0.2 as of this writing) - no upload throttling, though.

How to Test a Throttle Position Sensor

What is a Throttle Position Sensor?

The Throttle Position Sensor (TPS) tells your car’s computer how far you are pressing the gas pedal. The car’s throttle is an opening to the engine that opens or closes based on how much air the engine needs. The more you step on the gas pedal, the more air an engine needs to breath in, and therefore the throttle opens accordingly. The TPS sensor reads the position of the throttle to help determine the amount of fuel that needs to be delivered to the engine.

_____________________________________________________________

The perfect gift for any auto enthusiast: A gift certificate from Tire Rack.

What happens if the sensor is defective?

There are numerous issues that can result from a defective TPS. These symptoms can range from rolling-idle, engine stalling, a no-start condition, rich (heavy fuel) or lean (low amounts of fuel) conditions, higher than normal emissions, erratic acceleration, to poor shifting performance in an automatic transmission.

How much does the sensor cost?

Sensors range from several hundred dollars to $27.30 on Amazon . You can check for pricing on other online parts stores like Auto Parts Warehouse .

How the Sensor Works:

A TPS is a simple electronic device called a potentiometer. To better understand how to diagnose a TPS, we need to learn how a potentiometer works. A potentiometer is a variable resistor connected to a dial, and it provides a voltage value based on the position of the dial. The image below shows a basic drawing of a potentiometer.

As seen above, a potentiometer has three connections.

Connection A: Voltage Reference

In your car, this is typically 5 volts. When a car’s computer is expecting a signal from a sensor, it has to know the range (maximum and minimum). Close to 0 volts is normally the minimum, and 5 volts is typically the maximum. As an example, when a car’s computer reads 2.5 volts from the TPS, it may mean the throttle is opened by 50% (your foot is pushing the pedal half-way down). This would also mean that close to 0 volts would mean the throttle is not opened, and at near 5 volts the throttle is wide-open.

Connection W: Signal

This is a “short-cut” for electricity to flow. Electricity is lazy, and it will always take the path of least resistance. Instead of electricity flowing all the way around the rest of the resistor, it finds a short-cut through Connection B. This is the signal to the computer. This a voltage signal that varies due to the amount of resistance involved. The more the resistance (the more the dial turns clock-wise in the picture above) in the path of electricity, the more voltage is consumed, and therefore voltage is less.

Connection B: Ground

In order for any circuit to work, there must be a ground source. This completes the path for the electrical current to flow.

How to Diagnose a Throttle Position Sensor with a Multimeter

Using a multimeter one of the best ways to determine if a TPS is defective, and even a inexpensive multimeter will do.

1) Locate the TPS on your vehicle. Since the TPS by definition is monitoring the throttles position, it’s located on the throttle body.

The image below shows a red arrow pointing to the TPS.

For demonstration purposes only, I’ve removed the intake runner so you can see how the throttle body operates. This understanding will help when diagnosing the sensor.

a) There is a mechanical link from the vehicles gas pedal to the throttle body (note that newer cars are “drive-by-wire” and have no mechanical connection).

b) There is a “bar” that runs from the linkage, attaches to the butterfly-plate (the circular disk that acts as a door for air to come into the engine), and finally attaches to the TPS.

c) At closed throttle (the gas pedal is not pressed), the butterfly-plate is fully closed.

d) At Wide Open Throttle (WOT) (the gas pedal is pressed to the floor), the butterfly-plate is fully open, allowing maximum air to come into the engine. While moving the butterfly-plate, the TPS is rotating internally.

2) The next step is to ensure the sensor has the power is needs to operate. To do so, start by disconnect the wiring harness plug from the sensor. There will be a tab that is pressed or pulled up to release the plug from the sensor.

Connect the ground (black) lead of the multimeter to the ground (-, black) terminal of the battery, and set the multimeter to Volts DC.

a) Start by measuring on one side of the three-wire plug. Turn the key to the ON position, but do not try to start the car. One wire should read close to 0 volts (or zero volts). This is typically one of the wires on the far-left or far-right of the plug.

b) Measure the middle connection, which is typically the signal wire. This should also read close to 0 volts.

c) Measure the final connection, which should be 5 volts and is our reference voltage. If you do not read 5 volts here, there is an issue with the sensor receiving power, and there is a potential short wire upstream from the plugIf this is the case, follow the wire to see if there is any physical damage.

It’s important to note that as long as you have 5 volts on one connection, and close to 0 volts on the other two, that your wires are OK. Know that the signal wire is commonly the middle connection, and note where the 5 volts and ground connections are.

3) Reconnect the wiring-harness connector and back-probe the sensor on signal and ground. If you are unsure how to back-probe a sensor, check out how to here .

4) Connect the positive (red) multimeter cable to the signal wire (the middle connection), and the ground (black) multimeter cable to the ground wire (depending on orientation of Step 2). Set or leave the multimeter on Volts DC.

5) With the connections thus far, we should have about 0.9 volts on the multimeter. Exact readings will vary on make and model.

6) Rotate the throttle body linkage and notice the change in voltage. If you are uncomfortable with rotating the linkage, that is not a problem. Simply rotate the multimeter on the windshield so you can see the readings from within the car and step on the gas pedal. It’s the same thing.

7) If the TPS is operating correctly, there should be a smooth transition from base voltage (in my case around 0.9 volts) to maximum voltage (approximately 4.47 volts). Rotate the linkage or press the gas pedal slowly, and look for voltage “spikes”. A spike would be a sudden and drastic change either to a high or low voltage.

For example, if you are half-way through pressing on the gas pedal and are reading about 2.5 volts, when a sudden spike goes to 4+ volts, or less than 1 volt, this would signal a faulty TPS sensor.

Here’s why: TPS sensors physically get worn out. If you see a section of the TPS that spikes each time you pass it (either on the way up or back down), there is a break in the connection because the physical resistive component has been worn away. This voltage spike is sent to the vehicles computer, and the computer processes the information as a sudden pressing of the gas pedal, or the sudden release of the gas pedal.

Reference the video below to see how a good TPS behaves.

If the TPS sensor is faulty, it’s not hard to replace. Typically, there are just two bolts that hold it on. Simply remove the wiring harness plug, the two bolts, the sensor, and replace.

Throttle - Free download and software reviews - CNET

There is just no substitute for bandwidth when it comes to Internet speed. Whether it's water or data, the principle is the same: the bigger the pipe, the bigger (and faster) the flow. But that doesn't mean there's nothing you can do on your end to improve your online experience, especially if you're one of the many users still running dial-up connections. If you're trying to squeeze every bit of performance out of your Internet connection, you may want to have a look at Throttle. Throttle offers to maximize your PC's network settings, whether you're hooked up through a dial-up modem, home broadband such as cable or DSL, or even satellite, Wi-Fi, or LAN (there's even an Android option). It's a very simple tool that's designed to change your network settings, or change them back. Throttle is shareware that you can try for free for 28 days, though the trial version is limited to the minimum speed slider setting.

Throttle's dialog-style interface is quite simple: Boost slider, menus for selecting Operating System (we were using Windows 7) and Internet Type (cable modem), and Optimize, Restore, and Update buttons. The Help file explains how to use Throttle, but there's not much to describe: Set, optimize, and enjoy your enhanced connection speed -- assuming yours is improved! We downloaded and opened Throttle but then opened our browser and ran an online bandwidth test (several times) to gauge our connection speed; if Throttle made a significant improvement, it would show up as better results in bandwidth tests. So we set Throttle and pressed Optimize Now. Completing the process requires a reboot. We reran the bandwidth test, and our speed plummeted. We clicked Restore, rebooted, and ran the test again; our speed was restored. But we reran Throttle's optimizer again, this time with much better results -- very close to our "natural" settings.

We still had the best performance without Throttle rather than with it. But if you're reading this, you probably need help with your connection. It doesn't cost anything to try Throttle, and if it makes a difference, it's well worth its modest price.

Editors' note: This is a review of the trial version of Throttle 7.4.15.2013.
