P0420 - WOULOD THIS CAUSE MY CAR TO TURN OFF

Question

WOULD THE P0420 CODE CAUSE MY CAR TO TURN OFF WHILE DRIVING

Answer 1

The P0420 is for the catalytic converter, usually when the catalytic converter starts failing it will trigger the P0420 code, but when the catalytic converter is totally damage, it may start coming apart and it could cause the engine to stall. It's possible, but not likely that the catalytic converter is causing the problem.
