Okay, So my CEL light just came on for no reason the other day. Car is running perfectly fine. I couldnt figure it out but when I went to gas up, I noticed my gas cap was not even screwed on. Then I tried to put it back on but its stripped. So I will have to go buy a new gas cap. Question is, once I get a new gas cap, will the CEL go away on its own? Or does a tech have to turn it off?

it will go off on its own after a few drive cycles

is it still under warranty, they may give you a new cap.

I had to pull the Room(?) fuse, wait at least 60 seconds, then put it back in.

Oh I just bought one at Kragen for 6 bucks. It works fine. I will see if the CEL turns off in a couple days.

You might consider resetting it ASAP, just to make sure you're not running the car while something different is wrong.

I had my cap replaced under warranty. It is running better than it was - it had a slight knock, I replaced the plugs, knock still there. After they replaced the cap , no more knock. I put a new battery in it while I was at it.

just remove the battery cable for a few minutes that will reset it.....or go to autozone and have them erase it....CEL usually bugs me so i try to get it off there asap....

I vote for going to Autozone and having them read the code. Always good to know what it was, even though gas cap off is really good evidence it was one of the gas cap codes.

I'm curious - how did your cap manage to get stripped? The cap may be plastic, but those threads are pretty big.

Mazda has some sh!ty gas caps. I've had to replace mine a few times under factory warranty. My friend has a CX-7 and she had the same problem.

It ended up being just the gas cap. Bought a new one and the CEL turned off the following day.
