I know this light usually doesn't mean much. Maybe a bad oxygen sensor or some other smog item, but since I'm planning on a trip at the end of the week I just wanted to check with you experts to make sure it's no big deal, other than aggravating the hell out of me. I was planning on taking it in early this week for an oil change. Does the dealer charge much for a diagnosis of this light? Thanks to all.

I had a CEL come on a few weeks ago. Took it to the local tire place that mounted my new tires. They checked the CEL for free and reset it. It was an 0420 code which was the right side cat or left...can't remember which. They are 0420 and 0430. Anyway, call around and see if a local shop will tell you what the code is. Many will do it for free in hopes you will let them fix it. I'm not sure they can identify every CEL on the car but you might get lucky. My 08 Z06 needed a new cat and it only had 9000 miles. Thank god the cat warranty is good until 2/17! Good luck.

I was hoping my gas cap was loose but it wasn't. I hope it isn't the Cat. my 08 Z06 has about 45K miles on it, and I would hate to start spending big bucks on it. Thanks for your help!

I'll hit one of these in the morning. I have no idea what the dealer would charge me. Thanks.

Your cats are still under warranty. No worries if it is.

A 2008 with 47K miles is still under warranty on the cats?

You can buy a basic code reader for less than the price of an oil change. It's a good thing to have.

Get the code checked. It could be anything. Usually if it isn't flashing it isn't a huge deal but check it. If it's a front sensor it could make the car difficult to drive and damage your cats.

I see by most of the forum members that I need a code reader. Thanks!

It never did flash. Just came on when I started the car and stayed on. I'll have it checked before I take it on a trip. Thanks.

If you haven't checked the in service date on your vehicle...do it now. I got lucky with mine and the cats were still under warranty until 02/17. I think catalytic converters are 8 years covered from in service date.

Cats are an emissions component that the EPA imposes longer warranty lengths upon car mfgrs to extend to owners. I believe it is 8 years/80,000 miles.

I just got off the phone with my local Chevy dealer. Just to check the code starts at $110. WTH? Autozone, etc does it for free? That seems a little bit outrageous to me!

There is a huge Corvette dealer/repair shop where I live, but I've never used them. Maybe now would be a good time to start.

That's why they call them "Stealerships".

Sorry Rich, I didn't read down that far...
