Your car suddenly starts idling erratically at a traffic light, feels sluggish when you accelerate, and the check engine light comes on. These are classic symptoms of a failing Variable Valve Timing (VVT) solenoid, a common issue in modern engines. For Singaporean drivers in Malaysia, MyMechanic can provide on-the-spot diagnostics to pinpoint this frustrating problem.
VVT is a clever technology that allows your engine to change when its intake and exhaust valves open and close. This optimizes performance across different engine speeds.
The VVT solenoid is the component that makes this happen. It's an electronically controlled valve that directs engine oil to the camshaft actuator, which in turn adjusts the valve timing. When the solenoid fails, the timing gets stuck in one position.
A bad VVT solenoid will have a noticeable and immediate impact on your car's performance.
The number one cause of VVT solenoid failure is old, dirty, or low-quality engine oil. The solenoid has tiny passages and a small plunger that can easily get clogged with sludge and contaminants. This prevents the solenoid from moving correctly, leading to the symptoms above. This is why adhering to your car's recommended oil change schedule with the correct type of oil is so important.
If your Singapore-registered car is running poorly in Malaysia, don't guess what the problem is. Contact MyMechanic. Our technicians can come to your location, perform a professional diagnostic scan to confirm a VVT solenoid fault, and advise on the best course of action.
