My first SES code: Guessing it's the catalytic convertor.
My first SES code: Guessing it's the catalytic convertor. So my SES light came on today. The car runs and drives as normal as ever. I am guessing it's the cat only because my one cat went bad about 7 months ago and was replaced under GM's warranty.
Now my only question is will GM still replace the cat for me? Since then I got a new cat back and a new y pipe. The Y-pipe is the SLP one for stock manifolds so it fits right on up to the cats.

Go to an auto zone/ advance store and get them to read the code for you for free. It may be something else and knowledge is best when going into a dealership, if you chose that route. It could be a 02 sensor since the cat went bad.
Well I checked my gas cap and it seemed to be loose. I clicked it n a few notches then 10-15 miles later the light went away. Could that code have been thrown since the cap was loose? Air in the fuel line?
