Lexus ES: Transmission Range Sensor "A" Circuit (PRNDL Input) Signal Compare Failure (P070562)

Lexus ES (XZ10) Service Manual / Engine & Hybrid System / Hybrid / Battery Control / Hybrid Control System (for Nickel Metal Hydride Battery) / Transmission Range Sensor "A" Circuit (PRNDL Input) Signal Compare Failure (P070562)

DESCRIPTION

The shift lever position sensor sends 7 different switch signals to the hybrid vehicle control ECU. The hybrid vehicle control ECU uses these signals to detect the shift lever position (P, R, N or D). The hybrid vehicle control ECU also uses this information to determine the intended direction of travel (forward or reverse).

DTC No.

CONFIRMATION DRIVING PATTERN

HINT:

After repair has been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Click here

  1. Connect the Techstream to the DLC3.
  2. Turn the power switch on (IG) and turn the Techstream on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the power switch off and wait for 2 minutes or more.
  5. Turn the power switch on (IG) and turn the Techstream on.
  6. Slowly move the shift lever from P to S then back to P.
  7. Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
  8. Check the DTC judgment result.

    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 driving pattern again.
