There is 3 catalytic converter in your V6 Accord, one is in the front of the engine and the other one is in the rear of the engine. The DTC P0420 is for the rear catalytic converter and P0430 is for the front catalytic converter. The catalytic converter at under the car will not set a DTC. What DTC did you get? And which cat did your mechanic replaced?
