View Full Version : Check Engine Light P0430

03-18-09, 07:50 PM
I started getting a P0430 code about 2months ago, I reset the computer the first time to see if it would come back....and it did. So I did some research and it is telling me Bank 2 Sensor 2 error, the more I researched I came to the conclusion that my catalytic converter is most likely bad but..... I decided to replace the O2 sensors on bank 2 first and reset the computer...the light came back so I've come to the conclusion that I need a new cat.

Has anyone else experienced this issue??? My Escalade only has 75K and I can't believe my cat is bad already.
What would you replace it with???? Magnaflow Hi-Flow Cat, stock cat, no cat & O2 emulator, etc....

Any help is appreciated, Thanks

Not sure where you live at but No cat + 02 emulator= Failed emissions. As long as you dont live somewhere like CA I would probably go with the hi-flow over stock because it will be way cheaper and you will get a little added performance.

I may be wrong, but isn't the cat covered under GM warranty till 100K?
May be worth investigating. I know one of my other cars I bought new had a 100K warranty.
Take a peak at the warranty. I will try to find it in the owners manual.:hmm:
