Oxygen sensor issues on my 2011
About 6 months ago I was getting a CEL for P0148. I replaced the driver's side upstream (Bank 2 Sensor 1) oxygen sensor (and what a pain in the *** that was... Ended up taking it to a local exhaust shop who said the threads were all screwed up because of the heat and they had to replace the pipe that goes from the manifold to the catalytic converter). Everything was fine after that.
Yesterday I get another CEL for P0135 and P0030. It looks like the P0135 is for Bank 1 Sensor 1 (Passenger Side Up Stream?)... So now another oxygen sensor is bad?
Is it common for both to go out so close to each other and at only 50k miles? And I'm assuming the P0030 is just because of the P0135 code?
