This is the “fine” description of the trouble code and for example, P0420 means there is an issue at Bank 1, while the code P0421 means the issue is at bank 2. While the engine codes are quite logical, it’s very difficult to remember all of these OBD codes. I’ve created a ...
If catalyst efficiency has dropped below a certain threshold, this monitor will set a converter fault code (P0420 and/or P0430) and turn on the Check Engine light. As a rule, if converter conversion efficiency drops below 80 percent for any pollutant (carbon monoxide, hydrocarbons or oxides ...
