WarrantyNOTE: There is an oxygen sensor fault code, someone will replace the oxygen sensor, but a few days later the fault code again, is the oxygen sensor quality problem is broken? In fact, in many cases, although there is an oxygen sensor fault code, but the real problem is not necessarily the oxygen sensor, may be other aspects of the problem, for a few days after the failure light is on, indicating that the root cause of the failure has not been found. For example, the fuel quality is not good and too much carbon leads to bad combustion, which can damage the oxygen sensor and cause failure codes, of which the fuel problem accounts for the majority. If it is caused by the gasoline problem, do not change the gasoline only oxygen sensor, after changing, it will not be long before there will be a fault code. Oxygen sensor fault code needs in-depth analysis, find the root of the fault, do not replace at the beginning.
