AUTOMATIC TRANSAXLE SYSTEM, Diagnostic DTC:P0705

DTC Code DTC Name
P0705 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 Code DTC Detection Condition Trouble Area
P0705

Either condition is met:

(A) Any 2 or more of the following signals are ON simultaneously (2-trip detection logic):


  • NSW input signal is on.

  • R input signal is on.

  • D input signal is on.

(B) NSW, R and D switches are all off simultaneously.

  • Open or short in park/neutral position switch circuit

  • Park/neutral position switch

  • TCM

MONITOR DESCRIPTION

This DTC indicates a problem with the park/neutral position switch and/or the wire harness in the park/neutral position switch circuit.

The park/neutral position switch detects the shift lever position (P, R or D) and sends a signal to the TCM.

For safety, the park/neutral position switch detects the shift lever position so that the engine cannot be started when the shift lever is not in P or N.

The TCM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously, or receives no position signal at all.

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.

      ECT
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Neutral Position SW Signal

      PNP switch status/

      ON or OFF

      • ON: Shift lever in P or N

      • OFF: Shift lever not in P or N

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

      PNP switch status/

      ON or OFF

      • ON: Shift lever in R

      • OFF: Shift lever not in R

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

      PNP switch status/

      ON or OFF

      • ON: Shift lever in D or M

      • OFF: Shift lever not in D or M

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