Hello everyone

I am Chris. I call my baby CRV-Rex and it is already my third CR-V. It was built in Swindon UK in 2001. I use it everyday for about 60km and love it very much for the reliability and it is also the nicest looking CR-V model ever But since a few month I am desperately fighting with a nasty p0420 OBD-code which pops up all the time. I read already through many of the forum articles and did already changed the O2 plugs and the Cat, but after a few weeks the p0420 came back again. Now the CEL is again coming again every time I reset it. I'll open a thread in the CRV forum and describe in detail what I've done so far and hope to find the root cause of the issue with your help

Cheers and have nice ride!
Chris

 

Welcome! I'm sure you already know that it's a catalytic converter code. Giving what you've already done, have you checked for exhaust manifold leaks? Or your HO2S censor?
