问：检查引擎代码P0014和P054A

两个都代码请参阅可变阀正时机制的问题。该问题可能是机械的（基本时机关闭），液压（VVT依赖于发动机油压）或电气（有电磁阀，接线，端子）。不管问题如何，涉及的组件数量只有数量有限，某些项目，例如螺线管和关联的控制电路，都可以直接诊断。尽管有两个原因必须解决这样的问题：1）故障确实会降低发动机效率；2）如果由于存在故障而不断打开检查引擎灯，则在发动机控制中其他地方发生的任何新故障或其他故障的发生，您将基本上看不见您，因为无论如何检查引擎灯始终处于打开状态。换句话说，您希望关闭检查引擎的灯，以便您可以提醒问题。为了解决VVT问题，check engine light diagnosticis performed during which a certified mechanic from万博体育入口retrieves the codes from the PCM (that is, the specific codes that have caused the light to set) and then methodically tests the appropriate individual vehicle components or sub-systems to pinpoint the underlying fault. Once the faulty part or component is identified, it is explained to your satisfaction and the mechanic will let you know of the cost to repair. If you schedule the recommended diagnostic, the mechanic will resolve this promptly for you and all on a mobile basis right at your location. If you have further questions or concerns, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you get the best possible results.

这些代码适用于排气凸轮轴传感器或凸轮轴对准问题。需要进行长时间的精确测试，以尝试验证传感器，接线或凸轮轴螺线管是否是问题。如果代码被清除并且不返回，请继续驱动驱动，直到灯光再次打开为止。如果这样做，则应进行精确测试以隔离原因。
