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

   Connector and terminal 

   (E158) No. 110 - (E51) No. 5:

   (E158) No. 101 - (E51) No. 4:

   Is the resistance less than 1 Ω?

   Yes:  Go to  2.

   No:  Repair the open circuit in harness between ECM connector and tumble generator valve actuator LH connector.

2. CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR LH (SHORT TO GROUND)  .

   Measure the resistance between ECM connector and chassis ground.

   Connector and terminal 

   (E158) No. 110 - Chassis ground:

   (E158) No. 101 - Chassis ground:

   Is the resistance 1 MΩ or more?

   Yes:  Go to  3.

   No:  Repair the short circuit to ground in harness between ECM connector and tumble generator valve actuator LH connector.

3. CHECK FOR POOR CONTACT  .

   Check for poor contact in the tumble generator valve actuator LH connector.

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

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

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

   NOTE: The tumble generator valve actuator cannot be disassembled.
