Eric the Car Guy is here! He's visiting TRQ to explain check engine codes to you! In this video, Eric the Car Guy checks out code P0420, which usually has to do with the catalytic converter. The full description of the code is “Catalyst System Efficiency Below Threshold (Bank 1)” and it generally means that the catalytic converter is not doing its job, usually because it’s clogged. For vehicles with a second bank, like most V configured engines, P0430 means the same thing, but on the other side. Check out the video to learn more!
