I've been reading all the threads and posts about the common and hated p0420 check engine code. I currently have that code on my 99 4runner auto v6. I just need to triple confirm that I have a cali emissions vehicle before I purchase the rear oxygen sensor (from what I have read this seams the most likely cause). I DO HAVE 2 SMALL CATS... so is this 100% that I have a cali emissions vehicle?
THanks in advance
