engine code 420 and 430 If you find a P0420 code in your Subaru or Honda it s most likely the catalytic converter to blame It can also be caused by an exhaust leak or a bad oxygen sensor Check for vacuum leaks or other fuel mixture related engine codes Check for any exhaust leaks before the catalytic converter
The root cause of the problem is an engine that is emitting excessively high NOx emissions which in turn are caused by excessive combustion chamber temperatures Tailpipe emissions readings low in HC and CO levels with high NOx emissions are typically not caused by a defective converter Check Engine Light Codes P0420 and P0430 Replacing a catalytic converter or cat has become a big expensive drain on a lot of people s budgets these days I want to share some information about what s happening here with emissions testing and some ways to get emissions compliant without shelling out piles of money

Code P0430 indicates that the catalytic converter is not functioning efficiently therefore increasing the output of harmful pollutants by the vehicle P0430 Causes Faulty oxygen sensor Faulty air fuel sensor Worn or internally failing catalytic converter Most Common A leak in the exhaust system Misfire the root cause of The P0420 is the diagnostic code for a defective or underperforming catalytic converter However this code may pop up due to other reasons not directly related to the converter What Is The Catalytic Converter s Function
