Variable Valve Timing Solenoid: Testing and Inspection

INSPECTION





1. Remove the VTEC solenoid valve assembly from the cylinder head, and check the VTEC solenoid valve filter for clogging.
- If there is clogging, replace the engine oil filter and engine oil.





2. If the filter is not clogged, push the VTEC solenoid valve with your finger and check its movement.
- If the VTEC solenoid valve is normal, check the engine oil pressure.
