what is P2197 in 2006 ford explorer?

Question

My 2006 ford explorer generated error code P2197, what does it mean and what is the repair?

Answer 1

Hi there

This code is for the O2 sensor stuck lean on bank 2 sensor 1. Basically it means the O2 sensor isn't switching like it should. This could be because of a lean fuel mixture on bank 2. Caused by a problem with an intake leak or something. Most of the time however, the actual code is the result of a bad O2 sensor.
