2007 Mazda Mazda6 Q&A
2007 Mazda Mazda6 Question: Does a 07 mazda 6 have 2 catalyst convertors?
What are the codes? - Chevy Power
If it is 'California' emissions then it has two .It sounds like it would be worth at least having it diagnosed at the dealer , then possibly ask friends etc. for references to a trustworthy shop in your area to do the repairs. Beware...if you have emissions inspections in your region , some aftermarket converters will not perform efficiently enough to pass inspection , depending on how they do the testing. On a lot of newer vehicles software problems can mis-interpret sensor inputs and cause 'false codes' or errors leading to (unintentional)mis-diagnosis. NOT that this is the case , but at $1200.00 , might be worth a check-in at the dealer. Good luck. ZOOM ZOOM? - ziptie12
Did you ever have your issue resolved. I'm having the same code with my 04 mazda and I passed smog emissions in CA but failed visual and functional due to the check engine light being on. I want to fix the right problem and not spend too much on replacing the CATS at this point. - rforrey
