Monitor Description

These DTCs indicate a problem with the park/neutral position switch assembly or the wire harness in the park/neutral position switch assembly circuit.

The park/neutral position switch assembly detects the shift lever position and sends signals to the ECM.

For safety, the park/neutral position switch assembly 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 assembly sends a signal to the ECM according to the shift lever position (P, N, R, D or S).

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