Hi, I'm new to the forum and have a question in regards to my 02 sentra GXE.
The check engine light has been on for the past few months, I've had it checked by a dealer as well as an outside mechanic. They all came up with the same reading, the oxygen sensor. I've replaced three sensors within the past few months and still the light is on.
Does any one have any idea whats going on? Could it be the ECM comp.? And if so, how much in the whole can I expect to get in?
Thank You

sounds like its an exhaust leak if the light keeps coming on after replacing all the sensors.
