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 ECM.

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 ECM according to the shift position (P, R, N, or D). The ECM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The ECM will turn on the MIL and store the DTC.

INSPECTION PROCEDURE

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (BATTERY - PARK/NEUTRAL POSITION SWITCH)


    1. A01CAR1E01

      Disconnect the 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
      D3-2 (RB) - Body ground Engine switch on (IG) 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. CHECK HARNESS AND CONNECTOR (OUTPUT SIGNAL)


    1. A01CAR1E02

      Turn the engine switch on (IG).

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

      Standard voltage
      Tester Connection Switch Condition Specified Condition
      D3-4 (B) - Body ground Engine switch on (IG) 11 to 14 V

    NG

    CHECK CRANKING HOLDING FUNCTION CIRCUIT

    OK

  3. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY


    1. A01CAUVE01

      Disconnect the park/neutral position switch 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
      4 - 5 P and N Below 1 Ω
      Except P and N 10 Ω or higher
      2 - 6 P Below 1 Ω
      Except P 10 Ω or higher
      2 - 1 R Below 1 Ω
      Except R 10 Ω or higher
      2 - 9 N Below 1 Ω
      Except N 10 Ω or higher
      2 - 7 D, S, "+" and "-" Below 1 Ω
      Except D, S, "+" and "-" 10 Ω or higher

    NG

  4. CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH - ECM)


    1. Connect the park/neutral position switch connector.

    2. Disconnect the ECM connector.

    3. A01CC3EE04

      Turn the engine switch on (IG), and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.

      Standard voltage
      Tester Connection Shift Position Specified Condition
      D41-73 (P) - Body ground P 11 to 14 V
      Except P Below 1 V
      D41-54 (N) - Body ground N 11 to 14 V
      Except N Below 1 V
      D41-53 (R) - Body ground R

      11 to 14 V*

      Except R Below 1 V
      D41-56 (D) - Body ground D and S 11 to 14 V
      Except D and S Below 1 V

      Tech Tips

      *: The voltage will drop slightly due to the turning on of the back up light.


    NG
