Celica Forums General Discussion General Check engine light

Ok i have seen the pdf file on the check engine light in the tech info section, but it talks about engine problems with the fuel injectors and misfires...my check engine light comes on pretty much on every new tank of gas i put in the car. Dealer says that it is a gas cap pressure problem, they run it thru a 2 hour test and it comes back clean = engine light out until i refill the tank. Then it is good for a week and it comes back on.

its not me i have screwed the cap on as tight as it will go.

anyone with a 2000 GTS have a problem like this please offer any information or advice

thanks.

Yeah, I have a suggestion for you:

If they can't fix that problem within three attempts, that's a lemon. Erego, new car for you

I've got a GTS and havn't had that problem. Did they replace your gas cap with a new one? Try that if they havn't.

its an evaporation problem, check your intake hoses, this happens frequently when you install an intake system, if you dont have a RAI or CAI then ignore this and i dont know what to say
