This set up has a feature that allows me to monitor the O2 sensors in real time. Hope that helps Justin Justin, thanks for sharing your expertise on this site. Since then I get at random times, can be a couple of days to a couple of weeks before getting the P0420 code up this will reset straight away eveytime It tends to come on when you just cruise along at a steady speed. I checked the code and it was the P0420. Its the single most ignored code, and one the the most challenging to accurately diagnose.
