CHECK VALVE- As the name implies, a check valve is used in the air operated diaphragm pump of a car. It regulates the amount of air that comes into the engine when you push down on the gas pedal to get the car to move. This assembly ist he solenoid valve and pressure sensor.
Air control before the intake is managed by the solenoid valve. The solenoid valve "opens" on input of gas pedal, allowing air to come in. The pressure sensor, on the other hand, works like an assistant to monitor the an amount of air that flows into the engine and how pressurized the air is. The pressure sensor sends a message to the car's computer if the pressure of the air is too high or too low. That data is processed by a computer that adjusts how much air the engine is allowed to receive to maintain a smooth operation.
For example, when your engine in your automobile is an issue, it may be an ideal opportunity to replace the air control solenoid valve pressure sensor get together. Like any other component of your vehicle, this part can wear down over the years. You need to ensure that you are getting the proper assembly for your make and model of automobile. Not every part is compatible with every car!
Low Power: Is your car feeling weak, or have trouble going fast? It may be caused by solenoid valve not opening. You may want to check the wiring first. Check that the wires are properly identified and are not worn or corroded. If the wiring checks out, the solenoid valve itself may need to be replaced to resolve the issue.

High Idle: If your car idles too high (when it is running faster while not in motion), the solenoid valve may be stuck open. Analysis usually begins from checking wiring once again. If these wiring checks ar all okay, you may want to consider replacing the solenoid valve to get it functioning properly again.

Inspections for Wiring: Checking the wires that attach to your air diaphragm pump, as well as are connected to it, is a good idea. Check for any damage or signs of corrosion. Replace any damaged wiring immediately to prevent more serious issues.

Make sure to properly install your air control solenoid valve pressure sensor assembly as well. If not properly installed, they can lead to subpar performance and potentially damaging other components of your engine. This can result in costlier repairs later on. Simply do a search for a qualified mechanic to ensure that the assembly is truly installed correctly. They know how to do that properly and have the experience to do it for your specific make and model of the car.
