Throttle Position Sensor: Service and Repair

REMOVAL AND INSTALLATION






1. Disconnect the 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 the Throttle Position (TP) sensor electrical connector.






3. Remove the TP sensor screws and remove the TP sensor.

NOTE: The TP sensor is not adjustable.



CAUTION: Slide the rotary tangs of the TP sensor, rotated one quarter turn clockwise away from their final installed position, into place over the throttle shaft blade, and then rotate the TP sensor counterclockwise only to the installed position. Failure to install the TP sensor in this manner may result in excessive idle speeds.






4. To install, reverse the removal procedure.






5. Connect the battery ground cable.
