What is a VVT oil control valve?
The Oil Control Valve (OCV) is a a critical part used in every engine that is fitted with variable valve technology (VVT). A single control valve will regulate the supply of oil to a designated VVT hub, to advance or retard the timing by altering the camshaft angle position.
How much does it cost to replace an oil control valve?
The replacement cost of an oil control valve can be as high as $350. The price of the parts is between $100 and $200, while the cost of labor is between $80 and 160.
Is VVT solenoid the same as oil control valve?
An oil control valve (also referred to as a VVT solenoid) is an important component of a vehicle with a variable valve timing (VVT) system. The existence of the system aims to control the performance of the engine utilizing two methods to retard and advance camshaft angle.
How do I know if my VVT is working?
Common signs include a rough engine idle, the Check Engine Light coming on, and the engine stumbling when climbing hills or under load.
What causes VVT to go bad?
The dirty engine oil is the culprit cause of the faulty most of the time. Any debris or dirty in the oil will cause the stuck of OCV and VVT. Some Solenoids have oil filter screen inside the valve. Occasionally the faulty is caused by the screen is stuck with dirt.
What happens if you don’t replace a oil control valve?
Bad Oil Control Valve Symptoms But with a faulty oil control valve or VVT solenoid, excess engine oil may be introduced into the VVT system which can result in rough idling, stalling, or just poor engine running in general.
How do you know if your oil control valve is bad?
4 Symptoms of a Bad Oil Control Valve (and VVT Solenoid)
- #1 – Rough Idle.
- #2 – Poor Acceleration.
- #3 – Poor Gas Mileage.
- #4 – Check Engine Light.
Can a VVT solenoid cause overheating?
A vvt timing can affect combustion and cause a lean burning which will overheat the combustion chamber. Same goes with a partially faulty FPS sensor if equipped – these sensors do wear with no apparent symptoms before they finally die.
Can a bad VVT solenoid cause stalling?
A faulty oil control valve or VVT solenoid can introduce excess engine oil into the VVT system, which can result in rough idling, stalling, or just poor engine performance.
