article applies to Nissan, Toyota, Chevrolet, Ford, Honda, GMC, etc. The catalytic converter is p0420 nissan altima 2001 a part of the exhaust system that looks kind of like a muffler, although it's job is very different from that nissan maxima code p0420 of a muffler.

Repair as required. Use a scope to diagnose the oxygen sen
