P2276: O2 Sensor (Bank 2, Sensor 3) – Signal Stuck Lean

P2276 is a general diagnostic trouble code.  It means that the third “bank 2” downstream oxygen sensor (behind the catalytic converter) is continuously sending voltage that indicates a lean air/fuel mixture.   Having this code does not necessarily mean that the vehicle is running lean (although it can, but usually doesn’t).  P2276 is typically caused … Read more
