Q: Car stalled and couldn't go over 25 mph, also the steering wheel locked and couldn't move the car until I shut it off and start it

P0013sets if there is an open or short in the circuit to (and from) the exhaust camshaft oil control valve. That valve is an actuator or solenoid controlled electro-mechanical device. The underlying fault that caused the code to set could be in the circuit, that is the wiring, to the valve and not necessarily the valve itself. Diagnostic tests have to be carried out to pinpoint the exact fault (the code itself is not a diagnostic and thus the code cannot pinpoint the actual fault).P0014还指排气凸轮轴上可变阀时正时机制的问题。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。为了解决VVT问题，检查引擎灯诊断is performed during which a certified mechanic from万博体育入口retrieves the codes from the PCM (that is, confirms 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.
