Question

I have a 2012 ford edge with 65k on it. I have engine code p2196 and p2198 showing up. Codes say oxygen sensor. Could they both be bad at this point, or is it more likely something else?

Answer 1

Hi there

Since both codes are pointing to a rich fuel mix, it's likely not the O2 sensors at all. I would look for a dirty air filter or bad mass air flow sensor to be the cause of the codes.
