Component Inspection

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





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





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.
