VVT solenoid, cleaning

Note! Some variation in the illustrations may occur, but the essential information is always correct.

Check




Remove the VVT solenoid.
Blow compressed air into the oil feed hole (2). Air should come out through the B port (1)
If the duct seems to be blocked, go to the cleaning step.




Connect current to the solenoid.
The solenoid should click. It may be easier to hear the click with the solenoid in your hand.
Blow compressed air into the oil feed hole (2). Air should come out through the A port (3). If the piston jams or the solenoid does not work, the direction of flow will not change. If the duct seems to be blocked, go to the cleaning step.

Cleaning





Use: cleaner, 1161826 (1161828 US)
Allow to act for 5 minutes.
Blow compressed air into all holes from both directions and look for contamination. Carry this out with current on and off to ensure that no dirt remains in the ducts.
Rinse with cleaning agent.
Use: cleaning agent, 1161721.
Blow again.
Lubricate the solenoid with engine oil to prevent it jamming.
After cleaning, check the function by repeating steps 1 and 2 again. If the solenoid still does not work after cleaning twice, replace the solenoid.

Test driving and checking

Erase Diagnostic Trouble Codes (DTCs).
Test drive the car.
Check that no new DTCs have been stored.
