catalytic converter

[mmerrittjr]

hey, i'm new on here and my check engine light came on, i did a diagnosis and it said the catalytic converter, i'm wondering if it might be the o2 sensors or possibly another problem any insight would be helpful

What is the code?

If it is for the rear catalyst then your just looking at a new rear o2 sensor

what year and how miles are on your car?

Sweet... bring it to a dealer. Cat is warranteed for at least 80K unlimited years. Or is it 120K? Either way..

 

[JarenSTi]

^i thought it was only the 01 to 02 under 120k?

I dunno the mileage or years anymore. Key is ..I said dealer that thing. :th_thumbsup-wink:

i bought it used from carmax though, does that matter? when we checked with carmax they said they dont do cats in their garage. i also was told that pontiac dealerships have closed or been bought out or something.

No..it doesn't matter. Car manufacturers had problems with emissions equipment in the beginning and the public was outraged by the cost of a catalytic converter. So the EPA mandated that all car manufacturers had to warranty the cats to at least 80K miles.

My truck got all 4 new cats for free at about 75K miles. And ...then I er uh bought a new o2 sensor..lol
