About two years ago I had a new cat. Put on my 2004 nissan sentra, then about six months ago the check engine light came on the code was related to the cat. I replaced the sensor by the cat. And it did alright untill afew weeks ago the check engine light came back on reading the same code. Could it be I need another cat./
have the same problem?
