S : P0020, P1396. VVT LEFT-HAND BANK

S1 : CHECK GROUND CIRCUIT TO THE LEFT-HAND BANK VVT SOLENOID

1. Disconnect the VVT solenoid electrical connector, EN42.
2. Measure the resistance between the VVT solenoid electrical connector EN42 pin 2 (BG) and GROUND.

Is the resistance less than 5 ohms?
Yes
Goto S2

No
REPAIR the circuit between VVT solenoid electrical connector EN42 pin 2 (BG) and GROUND. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

S2 : CHECK CONTINUITY OF THE LEFT-HAND BANK VVT SOLENOID SIGNAL WIRE.

1. Measure the resistance between VVT solenoid electrical connector EN42 pin 1 (G) and PCM electrical connector EN16 pin 110 (G).

Is the resistance less than 5 ohms?
Yes
Goto S3

No
REPAIR the circuit between VVT solenoid electrical connector EN42 pin 1 (G) and PCM electrical connector EN16 pin 110 (G). For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

S3 : CHECK FOR SHORT TO GROUND AT THE LEFT-HAND BANK VVT SOLENOID SIGNAL WIRE

1. Disconnect the PCM electrical connector EN16.
2. Measure the resistance between EN61 pin 1 (RW) and GROUND.

Is the resistance less than 10,000 ohms?
Yes
REPAIR the short to GROUND. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

No
Goto S4

S4 : CHECK FOR SHORT TO BATTERY AT THE LEFT-HAND BANK VVT SOLENOID SIGNAL WIRE

1. TURN the ignition switch to the ON position.
2. Check for a voltage at EN61 pin 1 (RW).

Is the voltage greater than 1 volt?
Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

No
INSTALL a new left-hand bank VVT solenoid. CLEAR the DTC. TEST the system for normal operation.
