这P0362 code means that the PCM has registered a fault in either the primary or the secondary circuit of one or more ignition coils; this fault specifically pertains to the electrical circuitry that allows the individual coils to communicate with and be controlled by the PCM.
这ignition system in a vehicle uses ignition coils in each cylinder. The ECM controls the ignition coils, causing them to work with the spark plug to create a spark for ignition. If the ignition coils do not respond to an on or off command, the ECM alerts the PCM to store the P0362 code.
Most often, the P0362 code is caused by a faulty点火线圈。However, there may be other causes, including:
Some of the symptoms of the P0362 code may include引擎失火，发动机加速，发动机性能降低。这Check Engine Lightwill be on, and there may be other codes stored in the PCM related to the injector circuit or the cylinder where the malfunctioning coil is located. It’s possible that thefuel injector可能在受影响的圆柱体中完全禁用。
After an OBD-II scanner verifies the P0362 code, a technician should inspect of all the wiring, connectors, and otherelectrical components，寻找损坏，腐蚀，连接松动或其他故障。任何损坏的元素均应被更换，重新连接或修复。然后，机械师应清除代码并重新测试系统。如果代码返回，则机械师将继续进行其他可能的维修。
在许多情况下，P0362代码导致技术人员认为车辆需要简单的调整，并且不对问题进行彻底诊断。调整只能解决症状，并且可能不会阻止问题返回。
If an OBD-II scanner has detected the P0362 code, it indicates a serious problem that should be addressed right away. If left unrepaired, this code could indicate a malfunction that will eventually lead to engine failure.
为了解决导致P0362代码的问题，机械师可能会经过一组标准的维修。他们包括：
在执行每次维修后，从PCM中清除P0362代码并重新测试系统很重要。如果代码不返回，则机械师很可能已解决了引起问题的问题。通过在每次维修后进行此测试，机械师将确切知道问题是什么，并且如果将来是一个问题，将能够更好地诊断和修复问题。
In many cases, damaged circuits in the ignition coil circuit are caused by wildlife crawling into the top of the engine to seek warmth or shelter from bad weather. It’s a good idea to keep a vehicle in a garage, or covered, to prevent this from happening.
