Hi, I'm new to this forum. I'm a huge fan of the 3800 Engine, and owned Bonnevilles most of my driving life. Recently I bought my first Grand Prix(97) (Rebuilt Transmission/Intake Gaskets done, Everything else is pretty much Stock) I haven't had a chance to pick up a repair manual for it yet.
I have a question about a code that popped up after my check engine light came on the other day.
PO141 O2 Sensor heater circut bank 1 sensor 2.
The light was on for a couple days, and I was planning on looking at it this weekend, but this morning when I started the car the engine light was off. I'm looking for help at what I should start looking at. Is this just changing the O2 Sensor? Are there 2 on a Grand Prix? Any help would be great.
Thanks!
