check engine light comes on about every 10,000 miles, i'm on the 4th gas cap - is there anything else that can be adjusted?
How do I get rid of check engine light for gas cap. I replaced the gas cap and light is still on

Check Engine light comes on ALL the time from the gas cap not sealing properly. The two codes earlier in the thread are the same ones I keep getting. I finally just bought an OBDII code checker for about $30 and I reset the light myself as well as verify no other codes are popping up. Replacing cap doesn't seem to solve the problem for long if at all. Any other suggestions would be greatly appreciated to alleviate what is mostly a nuisance at worst.

check engine light comes on and stays on. Stopped for a while when I replaced a worn gas cap, but now comes on randomly, escpecially after i get gas.

Found the problem to be the gas cap but not until I got the correct one for my truck. They make two gas caps for the 04 Vue depending on the flapper inside the filler neck. If you look and its a plastic one then you need the correct cap for that one if its metal then you need the correct cap for that one. Problem was corrected from then on.

Mechanic at the shop says it is "vapor lock" due to a loose fitting gas cap that trips the sensor. I have to have the stupid light reset every 3,000 miles when I have my oil changed.
Yes, the gas cap will cause the light to come on. Replace it when you get the light to see if that is the problem.

Check engine light comes on and won't shut off. I have taken my car to two places and they cannot find any problems. I have changed the gas cap, but used a "genuine" Saturn approved replacement part. It's driving me CRAZY

Check engine light on; gas cap loose and turning freely, rather than "clicking" to lock.

The engine light is on. Dealer has said it is the converter. Before I spend that kind of money, I want to be sure it is not some other minor problem. Currently car has 97000 miles. Also I have intermittent starting problem.. The battery has been checked and it is less than a year old. What can this problem be? Thanks, Brent

After noticing check engine light refilling tank and putting on new cap resolved the initial problem. Now with newer cap it is starting again. I have been trying to reseat cap after filling tank. Worked until now. Have to buy another cap. 110,000 miles now.

Engine light has come on twice since I bought the car brand new in 04.both times I replaced the gas cap. Light went off. This time I had Auto Zone read my engine light. (They do it for free) and THIS time indicated an emmission problem. I don't believe it's the my car runs fantastically...gas cap is a little l will replace that first. I still have the original muffler/converter system..purrs like a kitten
