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 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 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.
Same issue. Also have problems filling tank with gas; backs up like it's full when it's not.
Check engine light has been on due to emission system. Unable to find solution
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.
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
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 on. gas cap tightened.
Check engine light on; gas cap loose and turning freely, rather than "clicking" to lock.
My check engine light would come on also because of the gas cap, but by replace the cap it stopped.
I have 2002 Saturn sl 1.5 whenever I put gas in,my service engine light comes on
Replaced gas cap
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.
SOLVED. I have had check engine light on for some time repair shop said nothing wrong is just gas cap. We bought locking gas cap from Amazon.com for Saturn. Had it on for a few days. Engine light finally went off.
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!
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.
emission light came on checked Manuel only to say to have it taken in to be serviced. found out it is a gas cap problem. don't you think when I explained my problem to the GM service center they should have suggested I check the gas cap first, before taking the car in.
