Q: Need to replace O2 sensor

asked by on

My Engine light is on. I think it might need an O2 sensor replaced.

When a Check Engine Light is illuminated it can be scanned by a tool. The code that gets read by the computer signifies what needs to be changed/replaced. An O2 sensor code quite possibly may be the case, but a mechanic can be certain by proper diagnosis of the Check Engine Light codes. After diagnosis, they will be able to pinpoint exactly what needs to be repaired.
