What is a camshaft timing 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 do you know if your oil control valve is bad?
Bad Oil Control Valve Symptoms
- #1 – Rough Idle. Under normal conditions, the VVT system activates at higher RPMs or when under load bearing conditions such as driving up a hill.
- #2 – Poor Acceleration. The engine will accelerate more slowly than normal.
- #3 – Poor Gas Mileage.
- #4 – Check Engine Light.
Can you drive with a bad oil control valve?
If you push a vehicle with a bad oil control valve too far, you’re going to have to deal with more than just poor fuel economy and some decreased engine performance. You should, therefore, stop driving a car as soon as you suspect problems with an oil control valve and have it checked out by a professional.
What does the camshaft control valve do?
Camshafts control the timing of the intake and exhaust valves. On a dual overhead engine, there is typically one intake camshaft and one exhaust camshaft per cylinder bank.
What are the symptoms of a bad camshaft position sensor?
Symptoms Of A Bad Camshaft Position Sensor
- Check engine light.
- Stalled engine.
- Unable to start the car.
- Rough idle.
- Reduced engine power.
- Bad gas mileage.
What part of the engine operation does the camshaft control?
In piston engines, the camshaft is used to operate the intake and exhaust valves. The camshaft consists of a cylindrical rod running the length of the cylinder bank with a number of cams (discs with protruding cam lobes) along its length, one for each valve.
What will a bad camshaft position sensor do?
Poor Drivability A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off.
