o2 sensor prob

My 07 jeep wrangler has been showing a problem with the o2sensor #2 bank two for a year last year I had the dealership replace it for over a$100 bucks and it dident stay fixed is there any permanent fix or way to eliminate it altogether so it can pass NY state inspection.

Post this in the JK Jeep Wrangler section...somebody will know something. Obviously I do not, or I'd save you the trouble.

Welcome to WF.

Welcome to the Forum

Although I drive a TJ, I was having the same problem. CEL would come on and go off randomly always showing one or another of the O2 sensors being the culprit. It could be that they replaced the wrong sensor or as in my case it was a leak in the manifold that was causing the bad O2 sensor codes.
