Throttle Position Sensor: Testing and Inspection

Function Check




Use a Tech 2 to check the TP sensor output voltage at closed throttle.
- The voltage should be under 0.25 volts.
- If the reading is greater than 0.25 volts, check the throttle shaft to see if it is binding. Check that the throttle cable is properly adjusted, also.
- If the throttle shaft is not binding and the throttle cable is properly adjusted, install a new TP sensor.
