Recommendation/Instructions:
If this concern is experienced, inspect the following areas before replacing the PCM per the SI diagnostics:
| • | If there is an APP or TP Sensor DTC stored with the P060E, such as a P2135 or a P2138, follow the SI diagnostics for the APP or TP Sensor DTC and repair as necessary.
