Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello, I'm Brandon - mazda tech.
Yes replacement cataytic converter will fixed the 3 codes. I agreed. Typically P0420 means the cataytic is bad and the only solution is to replace it.
You could get the same factory converter for cheaper price. http://www.ebay.com/itm/Genuine-Mazda-RX8-Catalytic-Converter-OE-OEM-N3Y3-20-55XA-/281482821753?hash=item4189af0079:g:d7QAAOSwajVUUmau&vxp=mtr
Check out the link I sent you.
Since you are doing the converter you should also replace the oxygen sensor at the same time. It is all related to each other.
The oxygen sensor is only $253 online. http://www.jimellismazdaparts.com/products/SENSOR/1901070/N3H3188G1A.html
I do not agree on replacing the wireless control module.
They should only charge you 2.5 hour labor time.
Please rate me positive for the prompt service, thank you!
