Can VVT cause loss of power?
If the VVT solenoid in your car is faulty, it can cause the engine to idle rough. The engine RPM will fluctuate which can directly result in a reduction of power generated by your car.
What does a bad VVT solenoid sound like?
A faulty VVT solenoid can prevent the VVT actuator from getting the oil pressure it needs. When this happens, you may hear a rattling noise or ticking noise from the engine. A rattling noise from the engine may indicate a bad VVT solenoid.
What causes a VVT to fail?
The most common cause of failure for both the VVT switch and the VVT solenoid is a lack of basic maintenance. If your oil is dirty, sludge can clog the screen on the solenoid, causing a failure. If the engine oil level is low, you will also experience problems with VVT operation.
What does a bad VVT solenoid do?
When the VVT solenoid is malfunctioning, the entire system can be compromised, which may result in intake and exhaust valves opening and closing at the wrong time. This typically causes the fuel economy to drastically reduce.
Why is my VVT pressure switch not working?
If the VVT solenoid is not working properly, the Check Engine light will come on and your engine will perform noticeably worse. The most common cause for VVT solenoid problems is dirty oil, which clogs the screen that sits between the solenoid and the VVT pressure switch.
What are the symptoms of a bad VVT?

Can a low oil level cause a VVT problem?
If your engine oil has not been changed out on schedule, it could damage the VVT solenoid, the VVT chain, and the gear drive. To avoid this situation, make sure to have your engine oil changed as recommended by the vehicle manufacture. Low oil levels can also cause problems with the VVT solenoid and other timing system components. 3.
What happens if the solenoid on a VVT fails?
If the VVT solenoid fails or is blocked, the lack of proper lubrication can cause the timing chain and gear to prematurely wear or break entirely. There are several other problems that may occur when a VVT solenoid is wearing out or has broken that may extend to complete engine failure.
