What happens when my throttle position sensor goes bad. When a TPS goes bad, then the car’s throttle body won’t function properly. It could either stay shut or it won’t close properly which is a severe issue. If it stays shut then your engine is not going receive air and it won’t start.

The throttle body is located between the air cleaner and the intake manifold of the engine. Most throttle bodies are made of aluminum. The throttle body is connected to the gas pedal of your vehicle with a linkage or flexible cable, which moves the throttle shaft when the gas pedal is depressed.

The throttle position sensor is mounted on the side of the engine throttle body. It has a three-wire potentiometer, meaning it varies its resistance based upon its position.

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.

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.

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.

Once the device (sensor) is detached, you can start off with the cleaning procedure instantly. Use the cleaning solvent, something like a carburetor fluid and a clean piece of cloth, to remove the grime and dirt around the area of the TPS unit. Also ensure that the solvent that is used to clean, dries out completely.
