What do i need to do?

Question

My recently purchased 2011 Ford Fusion threw the code P2196. The car never illuminated the check engine light, I have a vehicle monitoring system plugged into the OBD II port. I have noticed lower fuel economy this round compared to last fuel fill. If something were to need to be replaced, what would it be?

HI there

This code indicates an issue with the front O2 sensor. It basically means the sensor it's switching, but if the light wasn't on it's possible it's an old stored code. Here is some information on the possible causes for this code.
