Question

How can I fix the code P2631 on my 2003 Honda Accord EX V6? Light comes on and off when I put gas

Answer 1

Hi there,

This code is for the bank 2 front O2 sensor. Typically this is a failed sensor that isn't reading the exhaust properly and in most cases replacing it will resolve the problem.

This is the first O2 sensor on the side of the engine closest to the radiator.

Answer 2
