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 a signal to the ECM.

For security, the park/neutral position switch assembly detects the shift lever position so that engine can be started only when the shift lever is in the P or N position.

The park/neutral position switch sends a signal to the ECM according to the shift 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. and will illuminate the MIL and store this DTC.

  1. DATA LIST

    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.

    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.


    1. Warm up the engine.

    2. Turn the engine 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 / Neutral Position Switch Signal, Shift SW Status (P Range), Shift SW Status (R Range), Shift SW Status (N Range), Sports Shift Up SW, Sports Shift Down SW, Sports Mode Selection SW, Shift SW Status (D Range).

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