Throttle Position Sensor: Service and Repair

Removal Procedure
1. Disconnect the negative battery cable.
2. Disconnect the TPS electrical connector.
3. Remove the two screws and TP sensor from the throttle body.

NOTICE: Do not clean the TP sensor by soaking it in solvent. The sensor will be damaged as a result.





Function Check
Use a Scan Tool 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 it it is binding. Check that the throttle cable is properly adjusted, also. Refer to Throttle Cable Adjustment.
- If the throttle shaft is not binding and the throttle cable is properly adjusted, install a new TP sensor.








Installation Procedure
1. Install the TP sensor on the throttle body with two screws.
2. Connect the electrical connector.
3. Connect the negative battery cable.
