Variable Valve Timing Solenoid: Testing and Inspection

VTEC Solenoid Valve Test

1. Disconnect the VTEC solenoid valve 1P connector.




2. Measure resistance between the VTEC solenoid valve 1P connector terminal No.1 and body ground.




3. If the resistance is within specifications, remove the VTEC solenoid valve/oil filter assembly (A) from the oil pump, and check the VTEC solenoid valve filter (B) for clogging. If there is clogging, replace the VTEC solenoid valve filter, the engine oil filter, and the engine oil.




4. If the filter is not clogged, remove the VTEC solenoid valve and push it with your finger to check its movement. If the VTEC solenoid valve is normal, check the engine oil pressure.
