AUTOMATIC TRANSMISSION SYSTEM (for 1KD-FTV), Diagnostic DTC:P0705

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

DESCRIPTION

The Park/Neutral Position (PNP) switch detects the shift lever position and sends signals to the TCM.

DTC Code DTC Detection Condition Trouble Area
P0705

When either condition below is met (2 trip detection logic):


  • All switches are OFF simultaneously for P, R, N, D, 3 and 2 positions


  • 2 or more switches are ON simultaneously for D, 4, 3, 2 and L positions


  • Open or short in park/neutral position switch circuit

  • Park/neutral position switch

  • Shift lock control ECU (Shift lock control unit assembly)

  • 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 the engine can be started only when the shift lever is on P or N.

The park/neutral position switch sends a signal to the TCM according to the shift lever position (R, D, 4, 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 illuminate 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 ON.

    5. Turn the intelligent tester on.

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

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

    Tech Tips

    When the malfunction is found when the shift lever is in 3, start from *1. When the malfunction is found when the shift lever is not in 3, start from *2.
