hi, this code came up today when the mechanic scanned it. I haven't spoken with him yet & wonder if this is a small or large problem with the car?

Answer 2

Hi there,

This code is really a O2 sensor code. Typically the issue is with the sensor itself and replacement will resolve the issue. It is not a major problem and on average about a $250 repair.
