One of the biggest concerns that most people have about their car is how it runs and idles. Most car owners fail to realize just how many different components have to work together in order for this type of smooth running to occur. The variable valve timing is one of the main systems that is in charge of the idling and power delivering of the vehicle. The variable valve timing (VVT) solenoid is what helps to change the position of the car’s camshaft when needed. This solenoid operates on oil pressure and is an essential part of getting the performance that you need out of your vehicle. The VVT solenoid will be used each time that you run your vehicle and will help to provide the smooth running experience that you are after.
The VVT solenoid is able to change the amount of oil pressure that gets to the camshaft during times where the car is idling. Lowering this pressure will allow the car to run much better at idle and will prevent the oil pressure in the vehicle from getting too high. The constant use that this solenoid gets can lead to things like clogs in the screen that separates the solenoid from the actual VVT pressure switch. The only time you will have any interaction with this part is when it is broken due to the fact that it will not be inspected during routine maintenance.
When you start to experience issues that are related to the VVT solenoid, you will need to act quickly due to the negative effects that it can have on your engine. If you allow professionals to diagnose and fix the issues with your VVT solenoid, you will not have to worry about making mistakes that will only complicate matters.
When there is an issue with your VVT solenoid, you may start to notice a few of these symptoms.
- The gas mileage that you get is decreasing rapidly
- The performance level of your engine is declining
- The Check Engine Light is on
Taking notice of these warning signs can save you a lot of stress and aggravation. Getting the VVT solenoid on your car replaced will be easy when using the right professionals.
