DTC P2017: TGV Position Sensor/Switch Circuit High Bank 1: Notes

  1. DTC detecting condition: 

    Immediately at fault recognition

    Trouble symptom: 

    • Improper idling
    • Engine stall
    • Poor driving performance

    Wiring diagram:

CAUTION: Use the check board when measuring the ECM terminal voltage and resistance. Ref. to ENGINE (DIAGNOSTICS) (H4DO (EXCEPT FOR HEV))>GENERAL DESCRIPTION>PREPARATION TOOL>HOW TO USE CHECK BOARD .
NOTE: After the faulty parts are repaired or replaced, perform the final check in Basic Diagnostic Procedure. Ref. to ENGINE (DIAGNOSTICS) (H4DO (EXCEPT FOR HEV))>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE .

  1. CHECK DATA MONITOR  .
    1. Start the engine.
    2. Using the Subaru Select Monitor, read the value in [TGV Position Sensor R].
      NOTE: For detailed operation procedures, refer to "Common (Diagnostics)". Ref. to COMMON (DIAG)>DATA MONITOR .

      Is the value of [TGV Position Sensor R] 5 [V] or more?

      Yes  : Go to  2.

      No  : Even if DTC is detected, the circuit has returned to a normal condition at this time.

      Reproduce the failure, and then perform the diagnosis again.

      NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.
  2. CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR RH  .
    1. Turn the ignition switch to OFF.
    2. Disconnect the connector from tumble generator valve actuator RH.
    3. Start the engine.
    4. Using the Subaru Select Monitor, read the value in [TGV Position Sensor R].
      NOTE: For detailed operation procedures, refer to "Common (Diagnostics)". Ref. to COMMON (DIAG)>DATA MONITOR .

      Is the value of [TGV Position Sensor R] 5 [V] or more?

      Yes  : Repair the short circuit to power in harness between ECM connector and tumble generator valve actuator RH connector.

      No  : Go to  3.

  3. CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR RH (OPEN)  .
    1. Turn the ignition switch to OFF.
    2. Measure the resistance of harness between tumble generator valve actuator RH connector and engine ground.

      Connector & terminal 

      (E55) No. 2 - Engine ground:

      Is the resistance less than 5 Ω?

      Yes  : Go to  4.

      No  : Repair the harness and connector.

      NOTE: In this case, repair the following item:
      • Open circuit in harness between ECM connector and tumble generator valve actuator RH connector
      • Poor contact of ECM connector
  4. CHECK FOR POOR CONTACT  .

    Check for poor contact of tumble generator valve actuator RH connector.

    Is there poor contact of the tumble generator valve actuator RH connector?

    Yes  : Repair the poor contact of tumble generator valve actuator RH connector.

    No  : Replace the tumble generator valve actuator RH. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DO (EXCEPT FOR HEV))>TUMBLE GENERATOR VALVE ACTUATOR .

    NOTE: The tumble generator valve actuator cannot be disassembled.
