Could it be the 02 sensor
Ok the car has 90,000 miles, Is this code for the drivers side or passenger side cat?
I replaced the Cat on the drivers side at 80,000 miles with an aftermarket one. I know that this was not the ideal option but that said, no cat should go so quickly. Could this be the 02 sensor. How would I best test this before I spend a bunch of cash on parts? Any advise would be appreciated.
