Description This bulletin provides information related to the Throttle Position Sensor (TPS) for Sorento & Sedona models. Some Sorento & Sedona vehicles may exhibit diagnostic trouble codes P0121 and/or P1121. This condition mainly occurs in high ambient or desert areas, and can be related to the occasional increase in contact resistance due to excessive wear of the inner elements of the TP sensor. This bulletin describes the proper service and adjustment procedure for replacing the TP Sensor. – Service Procedure Replacement Procedure: 1. Turn ignition OFF. Remove engine cover and disconnect electrical connector from TP Sensor. 2. Remove two (2) retaining screws from TP Sensor and remove from throttle body. 3. Install new TP Sensor to throttle body. Install retaining screws and hand tighten lightly. Adjustment will be required. Re-install electrical connector to TP Sensor.
