Illustration for article titled P(ersistant)0156

When I bought the GS back in December, the CEL was on for code P0156, the rear O2 sensor. It’s not THAT difficult of a fix, but it requires peeling back part of the passenger’s side footwell carpet because the plug is under the center console. Changed it out yesterday, took it out for a test drive, CEL came back on. Same code. What else would cause that? Exhaust leak, maybe?
