Transmission Range Sensor "A" Signal Compare Failure

Any of the following conditions are met for 2 seconds or more (1-trip detection logic).

w/ Sequential Shift:

  • A malfunction in the P, R, N or D circuit is detected based on the shift sensor input pattern.
  • The input pattern of the shift lever position sensor circuit is P, R or N with the shift lever in M.

w/o Sequential Shift:

  • A malfunction in the P, R, N, D or B circuit is detected based on the shift sensor input pattern.
  • Wire harness or connector
  • Shift lever position sensor
  • Transmission control switch (Shift lock control unit assembly)
  • ECM

SAE Code:

P0705

MONITOR DESCRIPTION

This DTC indicates a problem with the shift lever position sensor, transmission control switch*1 or wire harness of their circuits.

The shift lever position sensor sends a signal to the ECM according to the shift lever position (P, R, N, D or B*2).

If the ECM detects a malfunction in the signal of the shift position sensor, it is suspected that a sensor or related component is malfunctioning. The ECM will then illuminate the MIL and store a DTC.

CONFIRMATION DRIVING PATTERN

HINT:

  • After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
  • When clearing the permanent DTCs, refer to the Clear Permanent DTC procedure.

  1. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  2. Turn the ignition switch off and wait for 2 minutes or more.
  3. w/ Sequential Shift:
    1. Wait with the shift lever in each position (P, R, N or D) for 2 seconds or more each with the ignition switch ON. [*1]
    2. Wait for 2 seconds or more with the shift lever in M. [*2]

      HINT:

      [*1] and [*2]: Normal judgment procedure.

      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

  4. w/o Sequential Shift:
    1. Wait with the shift lever in each position (P, R, N, D or B) for 2 seconds or more each with the ignition switch ON. [*1]

      HINT:

      [*1] : Normal judgment procedure.

      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

  5. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  6. Input the DTC: P070562.
  7. Check the DTC judgment result.

    Description

    NORMAL

    • DTC judgment completed
    • System normal

    ABNORMAL

    • DTC judgment completed
    • System abnormal

    INCOMPLETE

    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    N/A

    • Unable to perform DTC judgment
    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    HINT:

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
