AUTOMATIC TRANSMISSION SYSTEM, Diagnostic DTC:P0707, P0708

DTC Code DTC Name
P0707 Transmission Range Sensor "A" Circuit Low

MONITOR DESCRIPTION

These DTCs indicate a problem with the park/neutral position switch and 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 TCM.

For security, the park/neutral position switch 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 TCM according to the shift position (P, R, N, 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 or all contacts for shift position P, R, N, and D are off. The TCM will turn on the MIL and store the DTC.

  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 ignition switch ON.

    5. Turn the GTS on.

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

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

PROCEDURE


  1. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY


    1. Disconnect the A19 TCM connector.

    2. Measure resistance according to the value(s) in the table below when the shift lever is moved to each position.

      Standard resistance
      Tester Connection Shift Position Specified Condition
      A19-3(P) - L2-2(RB) P Below 1 Ω
      Except P 10 kΩ or higher
      A19-10(R) - L2-2(RB) R Below 1 Ω
      Except R 10 kΩ or higher
      A19-21(N) - L2-2(RB) N Below 1 Ω
      Except N 10 kΩ or higher
      A19-9(D) - L2-2(RB) D Below 1 Ω
      Except D 10 kΩ or higher

    3. Connect the A19 TCM connector.
