VTEC Solenoid Valve Test

VTEC Solenoid Valve Inspection

1. Disconnect the VTEC solenoid valve connector and the VTEC oil pressure switch connector.
2. Remove the VTEC solenoid valve assembly from the cylinder head assembly.




3. Measure resistance between VTEC solenoid valve 2P connector terminals No.1 and No.2.




4. If the resistance is within specification, check the solenoid valve filter (A) for clogging. If it is clogged, replace the solenoid valve filter, the engine oil filter, and the engine oil.
