T : P0020, P1396. VVT LH.

T1 : CHECK THE LH VVT SOLENOID RESISTANCE
1. Disconnect the LH VVT solenoid electrical connector, PI17.
2. Measure the resistance between pins 1 and 2 of the LH VVT solenoid.

Is the resistance 8 ohms?

Yes
Goto T2

No
INSTALL a new LH VVT solenoid. CLEAR the DTC. TEST the system for normal operation.

T2 : CHECK GROUND CIRCUIT TO THE LH VVT SOLENOID.
1. Disconnect the LH VVT solenoid electrical connector, PI17.
2. Measure the resistance between the LH VVT solenoid electrical connector PI17, pin 2 (B) and GROUND.

Is the resistance less than 5 ohms?

Yes
Goto T3

No
Repair the circuit between VVT solenoid electrical connector PI17, pin 2 (B) and GROUND. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

T3 : CHECK CONTINUITY OF THE LH VVT SOLENOID SIGNAL WIRE.
