If the gas cap light is on and the cap is tight / was replaced, you probably have a leak somewhere else on the "EVAP" system. In short this is the system that monitors whether your fuel system is leaking fumes or not (environmental concern). The usual cause for "leaking fumes" is a gas cap that does not seal properly, but your leak may be elsewhere. Piping for this system runs from your gas tank, to your filler neck, all the way to the engine compartment of the car (to a purge tank and solenoid). This system also has piping that lets your engine burn these fumes at regular intervals. Most automobile service garages have equipment to check for leaks in this system.

Hi I have a Mazda Tribute 2004 all of a sudden the emission light is on and won’t go off all the oils are good ,only had her 4 weeks has had a service when I got it please help

If when you pull the gas cap, you don't hear that quick suction loss/hiss, the gas cap needs replaced and will cause the light to come on and stay on till you replace the cap. These are sealed fuel systems.

Pump shuts of while refueling

a bad gas cap can cause this or if the vehicle is running while refueling
the evap system can also be malfunctioning causing it to not take fuel, i had the same problem with a 01 cavalier, i found out what the code was for the check engine light and the parts house sold me a gas cap and never had anymore problems. yours may not show check engine light for this problem look at the rubber oring seal on the cap if it is dryrotted then replace it.

What's your problem? check gas cap light is on and i already replaced the cap

Take the vehicle to a qualified repair shop an have the EVAP system smoke tested , this will find the leak . Too many thing's that could cause your problem . You don't want to keep replacing parts do you ? Could be a stuck open purge solenoid , a leak in one of the vapor lines , the part the gas cap screws into, vent valve stuck open . Service engine light on ? have checked for DTC'S - diagnostic trouble codes . You'll probably fine a evap code for a large leak.

$500.00 is a pretty steep price for an oil change!

If this is a gas cap issue, be aware that simply removing and replacing the cap will not immediately fix it. Most of the loose cap errors will only reset after the vehicle is driven for a period of time, not right as soon as you replace the cap. Speaking of replacing the cap, if the original has a bad seal, you aren't fixing anything doing what you've done.

Get a new gas cap first, then give it a while driving to see if it clears the error.

Check gas cap message

Do you make sure to turn the cap till it clicks about three times? Have checked the cap to make sure it is not bad and has a leak?

Gas Cap Error with Check Engine light

By "Replace the gas cap", do you mean put it back on, or buy another one? If you fuel these trucks with the engine running, or don't tighten the gas cap, the light will come on. It will also come on when the seal in your gas cap goes bad. I have had to replace the gas cap on my jeep and dodge already. It fixed the problem both times.

you have to understand that there is a leak in the system other than the gas cap for the evaporative system. The system needs to be professionally closed, and smoke introduced into to find the leak, and a through component check, eg.. purge valve vapor canister vent solenoid all functioning correctly
