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 signals to the TCM.

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 TCM according to the shift lever position (P, N, R, D or M).

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

Tech Tips

After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.


  1. Check the battery voltage is 10.5 V or more.

  2. Turn the engine switch on (IG).

  3. Wait with the shift lever in each position (P, R, N and D) for 60 seconds or more each.

  4. Turn the engine switch off.

  5. Perform steps (1) through (3) again.

  6. Check for DTCs again.

PROCEDURE


  1. READ VALUE USING GTS


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / ECT / Data List / Shift SW Status (P Range), Shift SW Status (R Range), Shift SW Status (N Range), Shift SW Status (D Range).

    5. Read the Data List according to the display on the GTS.


      Powertrain > ECT > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Shift SW Status (P Range) Park/neutral position switch status ON or OFF

      • ON: Shift lever in P

      • OFF: Shift lever not in P

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

      • ON: Shift lever in R

      • OFF: Shift lever not in R

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

      • ON: Shift lever in N

      • OFF: Shift lever not in N

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

      • ON: Shift lever in D or M

      • OFF: Shift lever not in D or M

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