Check Engine Light
 

Well I just made an appointment to have my car looked at on Friday. I was wondering if anyone might have some suggestions of what might have caused it. It came on on my way home from work. The car is running fine, no sputtering or bad acceleration. I got gas a day ago I checked to see if possibly the gas cap is loose. It wasn't. I checked oil and coolant, which are fine. Is there anything else I should check before I take it in?

Take it to Autozone or Advance Auto and have the code read, they do it for free. Then you'll know where to start.

I've thrown a gascap CEL by only clicking the cap a couple times, vs. my now habitual half dozen. Just have Autozone reset it for you and then go from there.

I'm going to run it up to Advance Auto. I'm hoping its possibly the gas cap. Does anyone know the code, if it is the gas cap?

dont know the number, but its called like "fuel line evap leak" or somehting along those lines

Code was p0456

yeah don't quite remember the number but it will be "evap leak very small" or "evap leak small" .....if the cap was completely missing/off it wold say "evap leak large" or very large but it should not say that

Sorry forgot to add evap very small leak. So I'm guessing it's a bad gas cap. I had the code cleared. I'll be purchasing a new gas cap. Thanks for the help. I appreciate it.

I have an RX-8 and I bought it one and a half year ago, it has 47000 km and I have problem with my check engine light, it stays on all the time. I also found some white foam to the bottom of the engine oil, and when I switch on my car a white smoke comes out from the exhaust, can anybody help and explain to me what is happening??

Go to Autozone or similar and have the CEL code read. There are too many possibilities to 'net-guess.

There's a TSB for foam in oil. http://www.finishlineperformance.com...50-06-1664.pdf

White-bluish smoke is generally indicative of excessive burning oil.

So it came on when you started the car, not while you were on the road, right?

That's one of the "gas cap" codes. P0455 is also common. The cap does not have to be obviously loose, and may not have any visible defects.

Oh no!! My cel just came on this morning!

Yep - they'll do that. See above. ;)

buy a new gas cap, like what, 15-20 bux from Mazda, seals better and will solve ur CEL.

If the gas cap was loose it take a few miles before the cell will go away.

Mine just came on Sat. morning. Time to go to Autozone and pull the code.

cel as well
 

where do u see this code at, or will their machine just let u know whats wrong with the vehicle.

Their scanner will show the code on it and they can tell you what it means.

awesome , ill go there after work.
