I recently got a PO430 code on my actron scanner. Do not trust what the dealer says. The dealer didnt even hook up a scanner they automatically told me that PO430 code is a bad cat. Not true. Try the cheaper fix first. See if you have any exhaust leaks or bad flange gaskets first (will cause back pressure) if you are getting this code gaskets buy 2 air flow ratio sensors and 2 O2 sensors for your cats. I did all the above and have put 400miles on my runner (after code erase) and I have not had any lights thus far. Toyota quoted me $3000.00 to fix both cats and would not listen to my plee to install new sensors (so I did so myself):der:
