Throttle Position Sensor: Service and Repair

Throttle Position Sensor:

REMOVAL
1. Disconnect battery ground cable.

NOTE: When battery voltage is removed from the Powertrain Control Module (PCM), all learned values will be cleared and reset to predetermined values. When battery voltage is restored to the PCM, the vehicle may exhibit certain driveability concerns. It will be necessary to drive the vehicle to allow the PCM to relearn values for optimum driveablilty and performance.

2. Disconnect Throttle Position (TP) sensor electrical connector engine control sensor wiring.
3. Remove the two throttle position sensor retaining screws.
4. Remove the throttle position sensor and throttle position sensor gasket.

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 throttle position sensor on the throttle body. Make sure that rotary tangs on sensor are in proper alignment with the throttle shaft blade.

NOTE: This TP sensor is non-adjustable.

2. Secure throttle position sensor to throttle body with two retaining screws. Tighten to 3-4 Nm (28-35 lb in).
3. Make sure that both the Idle Air Control (IAC) valve and gasket are clean.
4. Install IAC gasket on throttle body surface and mount IAC valve, securing it with two retaining screws. Tighten to 8-11 Nm (71-97 lb in).
5. Connect electrical connector to both the TP sensor and the IAC valve.
6. Connect battery ground cable.
