It works in tandem with the Engine Control Unit (ECU) to advance or retard the camshaft timing. Its primary function is to regulate the flow of oil to the hydraulic lifters or adjusters, ensuring optimal clearance between the valvetrain and the camshaft.
Recommended Maintenance Intervals for Camshaft Oil Control Valve
When the ECU signals a change in valve timing, it adjusts the oil pressure routed through this component. The camshaft oil control valve is the actuator for these systems.
An incorrect clearance leads to either a rattling engine or a sluggish, unresponsive valvetrain, both of which compromise performance and durability. Technicians utilize scan tools to monitor live data streams for oil pressure and VVT actuator position.
