Throttle Position Sensor: Service and Repair

REMOVAL

1. Disconnect negative battery cable.

2. Disconnect Throttle Position (TP) sensor from wiring harness.

3. If reusing TP sensor scribe alignment marks to position when reinstalling.

4. Remove two retaining screws.

5. Remove TP sensor.

INSTALLATION

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

1. Position the TP sensor so that the connector points opposite the Idle Air Control (IAC) solenoid. Then rotate TP sensor clockwise to align scribe marks.

NOTE: When TP sensor is installed on the throttle body, the connector will point toward the throttle body inlet.

2. Secure TP sensor to throttle body with two retaining screws. Tighten to 2-3 Nm (18-27 in lb).

3. Connect electrical connector to harness.

4. Reconnect negative battery cable.

NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module relearns its adaptive strategy. The vehicle may need to be driven 10 miles or more to relearn the adaptive strategy.
