What happens when throttle position sensor?
What happens when the throttle position sensor goes bad? If your sensor goes bad, then the car’s computer will receive inaccurate readings about the position of the accelerator pedal. This can cause your car to be sluggish, start jerking, have trouble shifting gears, or even stall in some cases.
How do you test a GM throttle position sensor?
How to Check the TPS Voltage on a Chevy Truck
- Open the hood on the truck. Remove the engine’s air cleaner by removing the wingnuts.
- Place the black probe from the voltmeter on the middle terminal inside the TPS. Place the voltmeter’s red probe on the the top, rearward terminal of the TPS.
- Put the key in the ignition.
Can a throttle position sensor 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.
How does the throttle position sensor work on a GM Truck?
Like the majority of throttle position sensors on modern fuel injected cars and trucks nowadays, the GM TPS is a three wire sensor. Each wire provides a specific type of signal to the TPS or to the PCM (Powertrain Control Module=Fuel Injection Computer). Below are the circuit descriptions of each: Circuit labeled 1 :
What are the DTC codes for the throttle position sensor?
TPS diagnostic trouble codes (DTC’s) stored in the vehicle’s computer’s memory. P0121: Throttle Position Sensor Performance. P0122: Throttle Position Sensor Circuit Low Voltage. P0123: Throttle Position Sensor Circuit High Voltage.
