DTC P2009: TGV Control Circuit Low Bank 1: Notes
- -
DTC detecting condition:
Immediately at fault recognition
Wiring diagram:
Engine Electrical System Ref. to WIRING SYSTEM>ENGINE ELECTRICAL SYSTEM .
CAUTION:
Use the check board when measuring the ECM terminal voltage and resistance. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>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)>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE
.
- CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR RH CONNECTOR (SHORT TO POWER SUPPLY)
.
- Turn the ignition switch to OFF.
- Disconnect the connector from ECM.
- Turn the ignition switch to ON.
- Measure the voltage between ECM connector and engine ground.
Connector & terminal
(E158) No. 102 (+) - Engine ground (-):
(E158) No. 111 (+) - Engine 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.
