When replacing the oxygen sensor, you should first ensure personal safety to avoid burns. Operation should be carried out after the engine is cooled, gently feel the thread of the oxygen sensor loose, and forcibly unscrew it at one time. If you need to replace the oxygen sensor, choose the pre - or post-oxygen replacement according to the damage. Unless both oxygen sensors are damaged at the same time, you do not need to replace the two oxygen sensors at the same time. Considering that the replacement of the oxygen sensor requires professional tools and knowledge, as well as troubleshooting the cause of the failure, it is recommended that the owner do not replace it by himself, but go to a professional maintenance point for repair
