AUTOMATIC TRANSMISSION 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

When condition (A) or (B) is met:

(A) Any 2 or more of the following conditions are met simultaneously

(2-trip detection logic)


  • NSW input signal is on

  • R input signal is on

  • D input signal is on

(B) All signals are off simultaneously for NSW, R and D switches

(2-trip detection logic)

  • Park/neutral position switch

  • Short in park/neutral position switch circuit

  • Harness and connector

  • TCM

MONITOR DESCRIPTION

This DTC indicates a problem with the park/neutral position switch or 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 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 or D). 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

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 engine switch off.

  3. Connect the intelligent tester to the DLC3.

  4. Turn the engine switch on (IG).

  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.

    Shift lever:


    • In R: ON

    • Not in R: OFF

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

    ON or OFF

    Shift lever:


    • In P: ON

    • Not in P: OFF

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

    Park/neutral position switch status/

    ON or OFF

    Shift lever:


    • In N: ON

    • Not in N: OFF

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

    Park/neutral position switch status/

    ON or OFF

    Shift lever:


    • In D or S: ON

    • Not in D or S: OFF

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

PROCEDURE


  1. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY


    1. A01GI3JE31

      Disconnect the E60 park/neutral position switch connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      6 (PL) - 2 (RB) Shift lever in P Below 1 Ω
      1 (RL) - 2 (RB) Shift lever in R Below 1 Ω
      9 (NL) - 2 (RB) Shift lever in N Below 1 Ω
      7 (DL) - 2 (RB) Shift lever in D Below 1 Ω
      6 (PL) - 2 (RB) Shift lever not in P 10 kΩ or higher
      1 (RL) - 2 (RB) Shift lever not in R 10 kΩ or higher
      9 (NL) - 2 (RB) Shift lever not in N 10 kΩ or higher
      7 (DL) - 2 (RB) Shift lever not in D 10 kΩ or higher

  2. CHECK PARK/NEUTRAL POSITION SWITCH ASSEMBLY (POWER SOURCE)


    1. A01GMJZE05

      Disconnect the E60 park/neutral position switch connector.

    2. Turn the engine switch on (IG).

    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      E60-2 (RB) - Body ground Engine switch on (IG) 11 to 14 V
