Throttle Position Sensor: Service and Repair

Throttle Body:

1. Disconnect the Throttle Position (TP) sensor from the wiring harness.
2. Remove the two TP sensor retaining screws and remove the sensor from the vehicle.
3. Install the sensor, ensuring that the rotary tangs on sensor are in proper alignment and that the wires are pointing down.
CAUTION: Slide rotary tangs into position over the throttle shaft blade, then rotate the TP sensor CLOCKWISE to installed position. Failure to install the TP sensor in this manner may result in excessive idle speeds.
4. Install the retaining screws and tighten them to 25-30 lbs. in. (2.8-3.4 N-m).
5. Connect the wiring connector to the TP sensor.
NOTE: The throttle position sensor is not adjustable.
6. Since the ECA will be receiving a different signal from the TP sensor, it may be necessary to adjust the idle speed. Refer to Idle Speed Adjustment for procedures.
