MONITOR DESCRIPTION

This DTC indicates a problem with the park/neutral position switch or 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 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 illuminates the MIL and stores this DTC.

Note

Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE


  1. READ VALUE USING GTS (NEUTRAL POSITION SW SIGNAL AND SHIFT SW STATUS)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary.

    5. According to the display on the GTS, read the Data List.


      Powertrain > Engine and ECT > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Neutral Position SW Signal Park/neutral position switch status OFF or ON

      • OFF: Shift lever not in P or N

      • ON: Shift lever in P or N

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

      • OFF: Shift lever not in P

      • ON: Shift lever in P

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

      • OFF: Shift lever not in R

      • ON: Shift lever in R

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

      • OFF: Shift lever not in D

      • ON: Shift lever in D

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