    Hi there everybody, I was wondering if someone could help me out with a couple of codes my car has started to throw. I took it to auto zone and they read codes p0161 and p0132.

    This past week, my check engine light has decided to come on, so i took it to my mechanic to see what the problem was. He told me that it had something to do with the cats. However, the exhaust system that i have said that it might require o2 sensors. could this be the problem?
