问：电磁阀故障或带有P0011检查引擎代码的凸轮轴？

我有一个2006 hyndai伊兰特。机械师告诉我，P0011的错误代码正在打开检查引擎灯。他说，必须更换或清洁螺线管。他说，一半时间，如果螺线管被清洁，将固定检查引擎的灯。他说，在更换之前先尝试一下。我在线阅读该错误代码P0011与凸轮轴时机的关闭有关。我很困惑。首先，该错误代码中的螺线管是否与点火系统的一部分不同？另外，他可以说是正确的，螺线管有问题吗？凸轮轴怎么样？ I don't want to replace the solenoid only to find out that the camshaft is the one that needs replacing. I see that this error code has to do with the engine oil, but I usually change the engine oil every 3 or 4 months and the oil level is never low or too high. What should I do? any help would be appreciated. Thanks.
