ELECTRONIC CONTROLLED AUTOMATIC TRANSMISSION SYSTEM, Diagnostic DTC:P0705/C2

DTC Code DTC Name
P0705/C2 Transmission Range Sensor Circuit Malfunction (PRNDL Input)

DESCRIPTION

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

DTC No. DTC Detection Condition Trouble Area
P0705/C2

Any 2 or more signals of the following are ON simultaneously.

(2-trip detection logic)


  • NSW input signal is ON

  • R input signal is ON

  • 3 input signal is ON

  • 2 input signal is ON

  • L input signal is ON

  • Open or short in park/neutral position switch circuit

  • Park/neutral position switch

  • TCM

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, 3, 2 or L).

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 turn on the MIL and store the DTC.

INSPECTION PROCEDURE


  1. DATA LIST

    Tech Tips

    Using the intelligent tester 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 intelligent tester to the DLC3.

    4. Turn the ignition switch to the ON position.

    5. Turn on the tester.

    6. Select the item "Enter / Powertrain / ECT / Data List".

    7. Follow the instructions on the tester and read the Data List.

PROCEDURE


  1. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY


    1. A01BB7VE27

      Jack up the vehicle.

    2. Disconnect the park/neutral position switch connector.

    3. Measure the resistance when the shift lever is moved to each position.

      Standard resistance
      Tester Connection Shift Position Specified Condition
      4 (B) - 5 (L) P or N Below 1 Ω
      Except P or N 10 kΩ or higher
      2 (RB) - 6 (PL) P Below 1 Ω
      Except P 10 kΩ or higher
      2 (RB) - 1 (RL) R Below 1 Ω
