drivers info center has check gas cap message on it. I checked gas cap it was tight and heard the 3 clicking sounds. I still am getting message of check gas cap on the driver info center,I purchased a new gas cap . I am still getting message and it tripped the check engine light. OBD TESTER, is giving code of P0449.
check engine light appears after pumping gas. or if riding long distances.
Gas cap could not be tightened and check engine light came on and wont'go off.
will have to go by dealership now. It's always something.
Full tank of gas but registers empty and engine light comes on.
Check engine light stays on due to the gas gauge.
gas cap vibrates loose and makes check engine light come on. Bought new cap and it still does it. Even with a lock gas cap.
Started getting messages to tighten the gas cap. I would check it but it never was loose. After 3-4 weeks the check engine light came on. OBDII said it was a bad gas cap so I replaced it with the first aftermarket cap I could find. Engine light never did go off. Started reading on the internet and found out that the gas cap has to be OEM or it will not work. When I compared my new cap to the original cap, which I had not yet discarded, I saw that they were really different. I took the "new" cap back and got a refund. No OEM cap was available so.....I got some mineral spirits and a microfiber cloth and cleaned the gasket on the original cap. I got a lot, and I mean a lot, of black residue off the gasket. I also cleaned the filler neck where the gasket makes contact. I put the original cap back on the car and within 10 miles the check engine light went off. Voila, problem fixed. I hope this saves y'all a bunch of $$$. And, yes I am from Texas Y'all.
fuel gauge bounces around after 3/4 take ,then my check engine light comes on and stays on.Did go out once but not now
My car just recently started sending a "check gas cap" message long after the gas cap has been opened.
It has not been repaired.
car ran rough after refueling and check engine light came on. took off gas cap and retightened and solved the rough running engine and check engine light went off after a couple of days. happened again and replaced the gas cap and no more problems.
The check engine light came on after replacing the fuel pump they said it was my gas cap. Turned out they didn't reconnect some tube when fuel pump was replaced. I was getting gas fumes inside the car on occasiona also.
at times the engine light will turn on, only to find out the gas cap is not properly placed, after gassing up.
My called me and said the check engine light came on I told her to pull over cut the car off and remove the gas cap and put it back on, that fixed the problem.
After tank is filled, fuel gauge goes to empty and engine light comes on. It does this for a few days and finally clears up. Chevy people say it needs fuel level sensor replaced (1000.00)
Check engine light came on around 50k. Code read that it was over evaporation system malfunction. Didn't even change the cap, just threw some Vaseline on it to create a seal and the light was reset. Didn't come back on for 3k miles. At that time the gas cap was replaced and the check engine light hasn't come back on.
Replaced the cap and the problem was solved.
The Engine light started showing up 2 days after gas fillup. I was just about to take vehicle to dealer however just happen to check on this site and I check the gas cap, which was indeed loose I tighten up the gas cap still light was showing for few miles, then I filled up the gas and then the light went away. Thank you for making us aware and saving $$
Check engine light won't go off. Fuel gauge is broken
I notice after I get gas my light with turn on after as while I would make sure I locked it right and it will turn off but I had to buy a new on eventually.. No more light.
check engine light on. Had a diagnostic done. Almost $ 500 later and it was a pressure/gas cap replacement issue.
