the vent in your fuel tank is not working properly
Gas Cap is not on tight, or the seal leaks and you need to replace the cap.
Check your gas cap. Lots of times its not on tight and causes your light to come on. After you check your cap remove your negative battery cable for a minute to clear the computer and then see what happens
first be sure it's the check engine light not the oil light big difference between the two. if it is the check engine light and the car was ran with the gas cap off it detected a evaporative emissions leak from the gas recirculation circut if you put the gas cap on and drive for approx one week the light may reset it self
your gas cap may not be installed correctly
Check your gas cap. I had a 2402 on my S40 and the gas cap was bad, easy fix...
It means that the EVAP system senses a leak in the gas cap, or filler neck. The most common problems that cause this, are a loose gas cap, or a defective gas cap.
Check your gas cap. Make sure the seal is still good. This will cause the check engine light to stay on and is an easy fix.
If the Suburban is E85 ready, but the gas cap says to avoid it, then avoid it until a check with a mechanic can be made. The gas cap might be a replacement gas cap if the vehicle was purchased used.
Check your gas cap to see if it is on right. I had that once and it was my gas cap not being on right.
Check your gas cap. My light would come on whenever the cap wasn't tightly on. Turn it until it clicks three times. You may also need a new cap if the seal around the cap is bad.
You have a problem with the EVAP system. Could be as simple as a loose or bad gas cap.
No, a loose gas cap can cause the check engine light to come on but not the low fuel light.
