I have the exact same thing. Did you figure it out yet?2008 Jeep GC 3.0L Diesel
Engine light came on and the code reader said P2245, P2238, P0130. All reference the O2 sensor Bank 1 sensor 1. It was a little difficult but not bad. Cleared the code with my OBD reader. two days later they all came back. I have read some references that this vehicle has two O2 sensors, but I can only find one, just below the turbo and before the Diesel particulate canister. I cleaned the electrical plug and made sure it was sealed and connected. Any one else have this issue. Is it possible to get a tuner to eliminated the O2 function. Obviously this is only used for emissions as its a diesel.
