MONITOR DESCRIPTION

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

The park/neutral position switch detects the shift lever position and sends a signal to the ECM.

For security, the park/neutral position switch detects the shift lever position so that the engine can be started
only when the shift lever is on 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
S).

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 illuminate the MIL and store the DTC.
