1996 Toyota Camry 4 cyl Front Wheel Drive Automatic 160000 miles
I had my car checked at a place to see why my check engine light came on. It said P0420, catalyst system efficiency below threshold-bank 1, and gave the possiblities of air leak in exhaust before rear HO2S (bank 1), AF sensor error, fuel system fault, and faulty catalytic converter. What does bank 1 mean? What might fixing the fuel system fault problem entail? If bank 1 means most likely cause, what would fixing the HO2S entail?
have the same problem?
