DIAGNOSTIC PROCEDURE

Step Check Yes No
1 CHECK CURRENT DATA. 
  1. Start the engine.
  2. Read the value of «TGV Position Sensor R» using the Subaru Select Monitor.
    NOTE: For detailed operation procedures, refer to "Current Data Display For Engine". < Ref. to SUBARU SELECT MONITOR . >
 Is the value of «TGV Position Sensor R» 5 V or more? Go to step 2  . 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 CONNECTOR. 
  1. Turn the ignition switch to OFF.
  2. Disconnect the connector from tumble generator valve actuator RH.
  3. Start the engine.
  4. Read the value of «TGV Position Sensor R» using the Subaru Select Monitor.
    NOTE: For detailed operation procedures, refer to "Current Data Display For Engine". < Ref. to SUBARU SELECT MONITOR . >
 Is the value of «TGV Position Sensor R» 5 V or more? Repair the short circuit to power in harness between ECM connector and tumble generator valve actuator RH connector. Go to step 3  .
3 CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR RH CONNECTOR. 
  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? Go to step 4  . 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? Repair the poor contact of tumble generator valve actuator RH connector. Replace the tumble generator valve actuator RH. < Ref. to TUMBLE GENERATOR VALVE . >

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
