Of the real problem is the catalytic converter, should the O2 sensor be replaced or not?

Customer: 2006 GMC Sierra 2500HD. Im getting two codes for the same sensor. P0137 and P2A01. Ive replaced the oxygen sensor with a new one brand name but still comes back. Could it be a fuse?

Had to replace oxygen sensor closest to engine. now I still have light on. Code says p2a01 oxygen sensor circuit range.

2007年5月3日 · Welcome. There are 2 possible reasons for this. First is the oxygen sensor. I would swap it to the other side and see if the misfire follows. The other possible cause is plugged catalytic converter for the left bank. If the oxygen sensor does not work, remove the left one and see if the misfire goes away.CHEVY ERROR CODES P2A01 & P2A04: Q&A for P2A01, P2
