What is a TPS fault?
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. When the throttle gets stuck in an open position than your vehicle will receive too much air and cause it to have a high or fluctuating idle.
What can a faulty TPS cause?
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 long do TPS sensors last?
5-10 years
TPMS sensors are designed to last for many years – 5-10 years is a likely lifespan.
What does p0122 mean on a TPS sensor?
A P0122 code means that the the vehicle’s computer has detected that the TPS (throttle position sensor) “A” is reporting too low a voltage.
What should the TPS sensor read at idle?
Typically, the sensor should read around 4.5 volts at wide open throttle and .45 volts with the throttle at the idle position. You can also test the TPS with a scan tool. Connect the scan tool to the diagnostic port, and scroll through the PID list until you find the TPS voltage or position PID.
What causes a failed throttle position sensor ( TPS )?
Common Problems. A failed Throttle Position Sensor (TPS) would be the most common causes for code 22. Testing the TPS circuit would involve checking voltage and ground from the ECM—5v is the normal reading between the ECM reference circuit and the ECM ground circuit at the TPS connector.
What’s the lower voltage limit for code p0122?
Depending on your vehicle, your TPS lower output voltage limit should be around.17 to.20 volts, and if the ECM detects that it has dipped below that, then it will trigger Code P0122. What Are the Symptoms of Code P0122?
