Hi Scotty. I have a 2012 Honda CRV with 187,000 miles and check engine light comes on. It’s a PO420 code then a day later the light will turn off. This will happens about every two or three weeks, the light comes on and then turn off the same day or the next day. What do you think the issue is. I hope it’s nots the catalytic converter. Thank you for your help. Paul

Have you looked up the possible causes of that code and diagnostic procedures?
