Cadillac ATS P2272:  B2S2 O2 Sensor – Stuck Lean

P2272 in the Cadillac ATS is a general diagnostic trouble code.  It means that the “bank 2” downstream oxygen sensor (behind the catalytic converter) is continuously sending voltage that indicates a lean air/fuel mixture.   This does not necessarily mean that the vehicle is running lean (although it can, but usually doesn’t).  P2272 is typically … Read more
