CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR RH CONNECTOR .
1. Turn the ignition switch to OFF.
2. Disconnect the connector from ECM.
3. Measure the voltage between ECM connector and chassis ground.
  Connector & terminal
  
  (E158) No. 13 (+) - Chassis ground (-):
  
  (E158) No. 52 (+) - Chassis ground (-):
Is the voltage 5 V or more?

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

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

NOTE: The tumble generator valve actuator cannot be disassembled.
