Since Greg already did a "what does this code mean?" thread, I thought I would ask too. I have an 03 on the little box and I've never heard of an 03... Unless someone can come up with something, I think I'll just clear it and see if it comes back. I know I've got a 45 stored in there but I'm pretty sure I know what that one is all about. The exhaust was dropped to swap out the transfer case and I think the right side O2 sensor didn't get plugged back in all the way. I'll check it when I get some free time, but in the mean time, what does a code 03 mean?!?
