O2 Sensor

[jrivera1041]

My 2011 Raptor popped a check engine light today. The code is P2270, and it points to the O2 sensor. Specifically the bank 1 sensor 2. Does anyone know which O2 sensor this is, and where to find it? A picture would be appreciated if anyone has one.

check wiring to the o2 sensor as this is a stuck lean code.

So your thinking its not the sensor but the wiring itself?

p2270 code

I took my raptor through some deep snow (12-14") and afterward got an engine code p2270, followed by p2096 - fuel trim system too lean, as well as a p219a- air fuel ration imbalance. It ran fine. Looked underneath and could see no obvious loose wire or other problem with O2 sensors. I was ready to take to the dealer, and was giving it a thorough wash and pressure washed the underside of the truck. Codes are now gone. I don't have a great explanation, but it saved me a few hundred dollars. Good luck

Was the snow powdery? That sounds like you packed the air box full of snow.
