2002 Jeep Liberty Limited Edition 2WD V6-3.7L VIN KSECTION Service and Repair
REMOVAL
The Throttle Position Sensor (TPS) is mounted to the throttle body.
1. Disconnect TPS electrical connector.
2. Remove 2 TPS mounting screws.
3. Remove TPS.
INSTALLATION
The Throttle Position Sensor (TPS) is mounted to the throttle body.
The throttle shaft end of the throttle body slides into a socket in the TPS. The TPS must be installed so that it can be rotated a few degrees. (If sensor will not rotate, install sensor with throttle shaft on other side of socket tangs). The TPS will be under slight tension when rotated.
1. Install TPS and retaining screws.
2. Tighten screws to 7 Nm (60 in. lbs.) torque.
3. Connect TPS electrical connector to TPS.
4. Manually operate throttle (by hand) to check for any TPS binding before starting engine.
5. Install air cleaner tube to throttle body.
