Question

Van has a miss fire code  what do I need to change

Answer 1

HI there,

This code is for the bank 1 O2 sensor, sensor #1. This is the O2 sensor on the back of the engine BEFORE the catalytic converter. This code may be the result of the engine running poorly so if you actually also have a code for a misfire, repair that first.
