Variable Valve Timing Solenoid: Testing and Inspection

1. Disconnect the 2P connector from the VTEC solenoid valve.




2. Measure resistance between the BLU/YEL (front/rear) terminals and body ground.

Resistance: approx 14 - 30 Ohms

3. If the resistance is within specifications, remove the VTEC solenoid valve 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.








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