Gas Cap warning question by one_roadking
Dec 22, 2007 (3:13 pm)

I have a 2005 Corvette coupe. The warning light saying "check gas cap" just came on and despite resetting it several times it comes back. I can't get a new one until Monday. Any problem with driving it that way? Would it change mileage or anything?
 
Car seems to run fine. Thanks

Its not going to hurt anything, unless, unless you try and get a smog check done with that stupid light on. lol Couldn't resist! The only time you need to worry about a warning light, is when your check engine light starts blinking while driving. When its just on, its telling you to have something checked out. When it starts blinking, the PCM fears serious engine, or smog equipement damage. Don't worry about the gas cap light. Either you have a bad gas cap, or a small leak has fooled the PCM into thinking you left it off.

Replace the cap. The system needs it on there to function correctly. I think the 2005's had more problems than the later models. If the car is still underwarranty it will not cost anything. In any case, it will not be horribly expensive.
 
But, yes, it could be something else in the fuel system rather than the cap. If the system is not air tight because of another leak, this message will be displayed.

Thanks for the info. I stopped today at a dealer and got a new cap. It didn't seem to help. They too said it would be fine to drive until I have time for a smoke test to find a leak.
 
It does seem the gas mileage is running a little behind right now.
 
Appreciate your insight

i think it takes a bunch of engine on/off cycles to clear the gas cap code...
my GTO gas cap failed as many do, and was replaced under warranty. GM later sent a letter saying that the gas cap warranty has been extended to 100k miles for all GTOs.
in my case there was no pressure seal, but also no OBD dashboard warning - i drove it like that for months. mpg seemed lower.

This is about the future economy issue, I like the line about Corvette MPG being
better than smaller sports cars. Gotta love torque and that tall 6th gear.

It's a great combination but the driver has to be sober about the tall gearing. If he lugs even a torquey V8 at an extremely low RPM, the engine wear is going to be considerable. Lugging is one of the worst things you can do to an engine, bar none. This is why some automakers won't even let you GO into overdrive until the engine is warmed up. (automatic transmission cars).
 
What a concept--- a hypermiler in a Corvette!
