How Does Throttle Position Sensor Work? The throttle position sensor is mounted onto the throttle body and measures the opening and closing movements of the throttle valve and these are transmitted to an engine control module, this information, as well as other measurements including; temperature, engine RPM and mass air flow (MAF), are used by the engine
How do I know if my throttle position sensor is bad? An unexplainable bucking and jerking in the vehicle.
Sudden idle surges.
Sudden engine stalling without any apparent reason.
Hesitation while accelerating.
Sudden surges in speed while driving on the highway.
Intermittently flashing of check engine light for no apparent reason.
Difficulties in changing gears.
What happens when you unplug throttle position sensor? If the TPS is not adjusted correctly as evidenced by a 500rpm idle, and hesitation with initial acceleration, unplugging the TPS connector should then cause a correct idle, and a normal acceleration.

How do you test a throttle position sensor?
Test the TPS using a digital multimeter. Make sure that it’s still working and, if necessary, visually inspect and test the wires and connector. If the sensor tests OK, erase the code. If it comes back or you notice a performance issue.
How do you fix a throttle position sensor?

How do you reset throttle position sensor?
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
Can I disconnect my throttle position sensor?
If the TPS is not adjusted correctly as evidenced by a 500rpm idle, and hesitation with initial acceleration, unplugging the TPS connector should then cause a correct idle, and a normal acceleration.
Can I clean throttle position sensor?
Cleaning the throttle body itself can be done using carburetor fluid and a clean cloth for the removal of light sludge. During this process, the throttle position sensor should not be cleaned due to the possibility of contamination or wire damage.
Will TPS cause engine not start?
Acceleration issues: A bad TPS may cause all sorts of power issues.
Your engine may start up but it will have little to no power and it causes it to shut off.
The only way a TPS will cause a no-start is if the TPS is busted/stuck, and the TPS is telling the computer that you’ve floored the gas.
How much does it cost to fix throttle position sensor?
The average cost for throttle position sensor replacement is between $164 and $179. Labor costs are estimated between $54 and $68 while parts are priced at $110. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
How much does it cost to have a throttle position sensor replaced?
The average replacement cost for the throttle position sensor is anywhere from $110 to $200. The parts cost is anywhere from $75 to $105 while the labor cost is anywhere from $35 to $95. In addition, you will have to account for any extra fees and taxes that get added on as well.
Can throttle body cause transmission problems?
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems. When a throttle body is not functioning correctly, some noticeable characteristics may be poor or very low idle.

What is the code for throttle position sensor?
The most common throttle position sensor code is the P0122 – Throttle Position Sensor/Switch A Circuit Low Input. It’s triggered when the ECU detects that the TPS circuit A is outputting a lower voltage than expected.
What should TPS be at idle?
At idle is should be zero or a couple of degrees.
Press down on the gas pedal very S-L-O-W-L-Y until the throttle is all the way open.
If the TPS has a worn spot, most likely it will be between 0 and 20 percent throttle opening.
Try holding the throttle between 0 and 20 percent to see if you get a steady reading.
Will a throttle position sensor?
The throttle position sensor (TPS) is part of your vehicle’s fuel management system and helps ensure that the correct mixture of air and fuel is delivered to your engine. This sensor can fail gradually, or all at once. In most cases, the Check Engine Light is illuminated if a TPS failure is detected.
How do you reprogram a throttle position sensor?
Steps on How to Calibrate Throttle Position sensor
Do you have to calibrate a throttle position sensor?
Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE. The signal on the chosen pin should sweep from approximately zero to five volts as you move the throttle from fully closed to fully open.
What happens if TPS is not calibrated?
What happens if TPS is not calibrated
Does TPS affect shifting?
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems.
