HOW TO WIRE VTEC

1. Disconnect the 1P connector from the VTEC solenoid
valve.
2. Measure resistance between the terminal 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
the 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.
