MONITOR DESCRIPTION

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

The park/neutral position switch detects the shift lever position (P, R, N, D or S) 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 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.

CAUTION / NOTICE / HINT


  1. DATA LIST

    Tech Tips

    Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

    Note

    In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.


    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect the GTS to the DLC3.

    4. Turn the engine switch on (IG).

    5. Turn the GTS on.

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

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

      • ON: Shift lever in P or N

      • OFF: Shift lever not in P or N

      		 When the shift lever position displayed on the GTS differs from the actual position, adjustment of the PNP switch or shift cable may be incorrect.
      Shift SW Status (P Range) PNP 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 PNP switch or shift cable may be incorrect.
      Shift SW Status (R Range) PNP 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 PNP switch or shift cable may be incorrect.
      Shift SW Status (N Range) PNP 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 PNP switch or shift cable may be incorrect.
      Sports Shift Up SW Sport shift up switch status ON or OFF

      • ON: Shift lever held in "+" (up-shift)
