Just before I went for my PA state inspection, my CEL came on.
I pulled three codes from it: PO133, P0420 and P1442.
The car's a 2002 Outback Sport with 141,000 miles on it. I had the cat replaced under warranty in the 85,000 mile range. From reading other posts, I know that the 133 and 420 indicate the front and rear 02 sensor failure. I am suprised they'd go bad at once though. Anything else it could be?
I have NO idea where the 1442 fits into this whole thing.
I have a terribly low budget at this point so any help I could get before throwing parts at this situation would be helpful.
