拥有平稳的跑车绝非偶然。许多不同的零件必须相互结合使用，才能使发动机顺利运行。The variable valve timing (VVT) system has a lot to do with how your car idles and runs. This system has both a solenoid and switch that help to regulate the amount of pressure that the system takes in. The oil pressure in a car is very important, which is why there are so many different components that are built to regulate it. The VVT switch records the amount of oil sent to the variable valve timing system and then sends this information back to the engine computer.

就像其他传感器和开关在您的汽车上一样，VVT开关的设计为终身部分。发动机的热量通常会导致汽车这一部分的维修问题。损坏此开关的另一个常见原因是没有定期换油。充满厚厚的污泥的油可以使这种开关粘住，并且几乎不可能完成其预期的工作。确保更换汽车中的油对于保持发动机的运行也很重要。

您通常在此开关变坏时通常会有的第一个迹象是检查引擎灯的照明。一旦亮起，您将需要带车辆才能进行诊断检查。机械师将万博亚洲客户端具有从OBD系统中提取故障代码所需的机械。这将帮助您缩小问题的范围，并进行适当的维修。

The following are some of the warning signs that your VVT switch is going bad:

• The engine is running very rough
• 燃油经济开始下降
• The car will not idle without cutting off

Without this switch to help regulate the flow of oil to the VVT system, it will be nearly impossible to get the performance you have come to expect from your engine. Have a certified mechanicreplace the failing variable valve timing switch消除车辆的进一步问题。
