MONITOR DESCRIPTION

These DTCs indicate a problem with the park/neutral position switch assembly and the wire harness in the park/neutral position switch assembly circuit.

The park/neutral position switch assembly detects the shift lever position and sends signals to the ECM.

For safety, 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, N, NSW, R or D). 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 turn on the MIL and store the DTC.

Tech Tips

Using the Techstream 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 Techstream to the DLC3.

  4. Turn the ignition switch to ON.

  5. Turn the Techstream on.

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

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

    Tester Display Measurement Item / Range Normal Condition Diagnostic Note
    Neutral Position SW Signal PNP switch status / ON or OFF

    • ON: Shift lever is in P or N

    • OFF: Shift lever is not in P or N

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

    • ON: Shift lever is in P

    • OFF: Shift lever is not in P

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

    • ON: Shift lever is in R

    • OFF: Shift lever is not in R

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

    • ON: Shift lever is in N

    • OFF: Shift lever is not in N

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

    • ON: Shift lever is in D or S

    • OFF: Shift lever is not in D or S

    		 When the shift lever position displayed on the Techstream differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect.
