So today my 2010 Ford Fusion’s CEL light came on. When I pulled the codes they were P2096 and P2270.

P2096 is Post Catalyst Fuel Trim System Too Lean Bank 1 and P2270 is O2 Sensor Signal Stuck Lean B1S2, so I’m thinking that I just have a bad O2 sensor.


Before I take it to a shop and have them look at it, does this sound like a correct diagnosis and how easy/hard would this be to fix on my own? I’m decently mechanically inclined but don’t have a lot of experience or a good place to work.

Heres a BMW Z8 Alpina for your time:
