Exhaust leaks are common and can skew oxygen sensor readings without setting other DTCs. Worn exhaust gaskets and corroded flex pipes are two common issues that are significantly less expensive and more effective than replacing a catalytic converter. Removing and cleaning the catalytic converter is another potential fix. After removing the catalytic converter, use a pressure washer to blast out any contaminants from the matrix. Be sure to flush the unit from both ends.

Another way to clean the catalytic converter is to soak it overnight in a combination of hot water and degreaser or laundry detergent. This process takes longer but is necessary to dissolve the deposits clogging up your catalytic converter.

After washing or soaking, be sure to dry the catalytic converter completely before reinstalling. Sometimes, the catalytic converter absolutely needs to be replaced like if it's broken internally or melted down.

If you have to replace your catalytic converter, make sure it lasts as long as possible with these tips. Actively scan device characteristics for identification. Use precise geolocation data.
