Throttle Position Sensor: Service and Repair

REMOVAL

Throttle Body:

1. Disconnect Throttle Position (TP) sensor from wiring harness.
2. Scribe a reference mark across the edge of the sensor and to the throttle body to ensure correct position during installation.
3. Remove two throttle position sensor retaining screws.
4. Remove throttle position sensor.

INSTALLATION


1. Install TP sensor. Ensure that rotary tangs on sensor are in proper alignment and wires are pointing down.


CAUTION: Slide rotary tangs into position over the throttle shaft blade, then rotate the TP sensor CLOCKWISE ONLY to installed position. Failure to install the TP sensor in this manner may result in excessive idle speeds.


2. Align scribe mark on throttle body and throttle position sensor. Secure sensor to throttle body assembly with two retaining screws. Tighten to 25-30 in lb (2.8-3.4 Nm).


NOTE: The TP sensor is not adjustable.



3. Connect electrical connector to harness.
