What does the VVT sensor do?
The variable valve timing solenoid is a component of the variable valve timing system that manages the oil flow depending on the engine speed and load. A VVT solenoid in good working condition improves performance and fuel efficiency.
Can a variable valve timing sensor be defective?
Any malfunction of the VVT solenoid is therefore certain to result in efficient fuel consumption. So if you notice a significant drop or increase in your average fuel consumption and smell of unburned fuel, it is very likely that your variable valve timing sensor is defective.
When to replace a variable valve solenoid ( VVT )?
Now that you know what all symptoms indicate variable valve timing solenoid failure, you must also know that it is imperative to replace a faulty VVT solenoid. Once you have diagnosed a problem in the variable valve timing solenoid, it is best that you either get it replace or do it yourself.
Why does the Check Engine light come on when the VVT is not working?
Your ECU monitors compare and report any activity going on in your car. If one of the current situations is not compatible with the predefined values, the check engine light comes on. As a result, when the VVT solenoid is not working properly, the check engine light will come on your dashboard.
How does the variable valve timing ( VVT ) system work?
Almost all modern cars use VVT technology to improve their performance and fuel economy. The VVT solenoid helps engines change their valve timing, ensuring that the performance is at its top without losing driveability on lower RPMs. Electronic principles of electromagnetism in the form of a solenoid valve control the oil flow to the camshafts.
Any malfunction of the VVT solenoid is therefore certain to result in efficient fuel consumption. So if you notice a significant drop or increase in your average fuel consumption and smell of unburned fuel, it is very likely that your variable valve timing sensor is defective.
What are the codes on the VVT sensor?
The two most common codes I’ve run across are P0011 and P0021 (Camshaft position sensor “Bank 1” and Camshaft position sensor “Bank 2,” respectively). These codes (like any code) don’t entirely mean the sensor is faulty, however the diagnostic charts will tell you to look at the VVT system for a fault and check the sensor as well.
