How does the Honda CRV VTEC oil solenoid work?

The VTEC system increases the amount of intake valve lift for increased power. It accomplishes this by turning a control solenoid ‘ON’ to allow oil pressure into the VTEC control passages to apply pins that will lock the intake rockers. When the oil pressure is present, the pressure switch signal will go high.

What’s the oil pressure switch on a Honda CRV?

The PCM simply doesn’t ‘know’ what the state of the intake valves are, so you end up with the symptoms you describe.
