P0414代码表明该汽车的计算机已在车辆的次要空气喷射系统中检测到问题。该系统通过将环境空气泵入排气管来减少排放。
If your vehicle’s computer has stored the P0414 code, it means that there is an issue with the secondary air system. This system is used to pump air into the car’s exhaust in order to reduce emissions by accelerating catalyst operations. If there is a variation of more than 10% from the manufacturer’s specifications, the car’s PCM will note this and usually store the code. It is also possible that the Check Engine Light will turn on, although this is not the case in all instances, as some vehicles require more than one erroneous operation to set the code.
There are a number of potential causes for the P0414 code, although it should be noted that this is code is seen more often in cold weather than in warm weather. Possible causes include the following:
您会发现P0414代码的症状很少。它们包括以下内容：
The first step in diagnosing the P0414 code is to connect an OBD II scanner to the car’s port (usually found under the dash on the driver’s side). The stored code or codes will be read, and then cleared. The technician will then test drive the vehicle to see if the code resets, as well as to duplicate any symptoms the driver mentioned.
下一步是检查空气注射软管或线条的状况（有些汽车使用钢管道，而另一些则使用橡胶软管）。接下来，技术人员将检查泵上的单向检查阀。如果空气两种方式移动，则阀门不好，必须更换。在某些情况下，这就是所需的一切。但是，如果有足够的水分进入泵，也可能需要更换泵。
如果检查阀测试良好，则机械师将需要检查线束是否有损坏的迹象以及腐蚀的连接。
这里犯的最常见的错误之一是假设泵已经失效并更换了泵，而无需检查损坏或腐蚀连接的线束。由于其位置，线束可能会被热的废气燃烧。
The P0414 code is very serious, as it will affect the drivability of your car, as well as your safety while on the road. One of the symptoms of this code is the possibility of the engine stalling while idling, which can leave you stuck in traffic. Have it diagnosed and repaired immediately.
所需的维修将取决于P0414代码的实际原因。但是，可能的维修包括以下内容：
It is crucial for mechanics to verify the condition of the one-way check valves before the pump, as replacing the pump but not the check valves in the lines will result in the new pump failing prematurely.
