I pulled an error code PO0125 from my wifes truck last night and don't quite understand it's meaning. There were two possible reasons for the code. the first is an over temp of exhaust gases I guess and the other was a coolant issue.I'm leaning toward a possible 02 sensor because I'm certain it's not the coolant. I figured I'd ask the pros here what you all thought before I went out and purchased a $180 sensor <img src="/forums/images/graemlins/confused.gif" alt="" />
