MONITOR DESCRIPTION

This DTC indicates 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 a signal to the ECM. For security, 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, 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 illuminates the MIL and stores this DTC.

      		 When the shift lever position displayed on the GTS differs from the actual position, the adjustment of the park/neutral position switch assembly or shift cable may be incorrect.
      Shift SW Status (N Range)

      Park/neutral position switch status/

      OFF or ON

      • OFF: Shift lever not in N

      • ON: Shift lever in N

      		 When the shift lever position displayed on the GTS differs from the actual position, the adjustment of the park/neutral position switch assembly or shift cable may be incorrect.

      Park/neutral position switch status/

      OFF or ON

      • OFF: Shift lever not in D or M

      • ON: Shift lever in D or M

      		 When the shift lever position displayed on the GTS differs from the actual position, the adjustment of the park/neutral position switch assembly or shift cable may be incorrect.
