Throttle Position Sensor: Service and Repair

REMOVAL
1. Disconnect negative battery cable.

NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the Powertrain Control Module (PCM) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.

2. Remove throttle body.
3. Disconnect Throttle Position Sensor (TPS) from wiring harness.
4. If reusing TPS, scribe alignment marks to position when reinstalling.
5. Remove two retaining screws.
6. Remove sensor.

INSTALLATION

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

1. Position the TPS so that the pigtail points toward the Idle Air Control (IAC) valve.
2. Secure sensor to throttle body with two retaining screws. Tighten to 1.2-1.8 Nm (11-16 lb in).
3. Install throttle body.
4. Connect electrical connector to harness.
5. Reconnect battery negative cable.
