Check engine light coming on with the catalytic converter already replaced


Recommended Posts

We have a 2013 Honda Accord that a few years back had the check engine light come on and the dealership replaced the catalytic converter with a Honda part that was covered. Now two years later the light is coming on again and they are saying it's an emissions code (Code P0420) and we need to replace the exhaust pipe and muffler at a cost of $3300. Is that possible? I have never heard of the exhaust causing a check engine light. Does that make sense and also could it be something else?
