1. Visual inspection of catalytic converter - Physical damage? - Is extreme discoloration present on the converter? (gentle reddish-blue hue is normal, especially after high-speed highway operation). 2. Leak check embracing entire exhaust system Seal leaks and conduct road test 3. Remove O2 sensors and visually inspect for particles, extreme discoloration, catalytic converter residue visual inspection through sensor holes in catalyst matrix as indicated. 4. If O2 sensor malfunction is suspected: Consider replacing O2 sensor (Did any known sensor faults or malfunctions occur prior to the catalyst fault entry being registered?) 5. Replace catalytic converter for the affected bank |
