Monitor Description

This DTC indicates a problem with the park/neutral position switch or the wire harness of the park/neutral position switch circuit.

The park/neutral position switch detects the shift lever position and sends a signal to the ECM. For safety, the park/neutral position switch detects the shift lever position so that the engine can be started only when the shift lever is in P or N.

The park/neutral position switch sends a signal to the ECM according to the shift lever position (P, R, N, D or M).

The ECM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The ECM will then illuminate the MIL and store a DTC.
