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 about every 10,000 miles, i'm on the 4th gas cap - is there anything else that can be adjusted?
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.
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
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.
My check engine light would come on also because of the gas cap, but by replace the cap it stopped.
I have tried multiple gas caps and all seem to set of the light within months. I have tried clicking the cap a certain number of times; my repair shop has used graphite thinking it was maybe dings in the inside of the cap area; and nothing seems to work. any help would be much appreciated! It is soooooo frustrating.
2 emissions codes. Repaired. Light came. Sick on 2 weeks later. Put new gas cap on. Light off for 2 weeks. Now light back on
we had this issue with a previous Saturn Vue. We found that if we replaced the gas cap with a GENUINE part from GM the problem went away. Given that they seem to eat gas caps and they no longer make this car we are going to buy several!
