    You will have to have the system scanned,then diagnose/repair the problem. Too many reasons for the check engine light to come on, nobody can tell without a system scan. Let us know what the DTC is. DTC = Diagnostic Trouble Code

Take the vehicle to an autoparts store and have them use a scan tool to retrieve any fault codes that are stored in the computer. Most parts stores will do the scan for free. Getting the codes will show what faults in what systems the computer has identified. Hope this helped and best wishes.

Check engine light stays on


The 'check engine' light comes on when almost anything goes wrong, from a loose gas cap to computer systems; low fluid levels to a bad catalytic converter. A common problem is the gas cap not screwed on correctly. This has an easy remedy. Screw the cap off and then carefully seat it and screw it back on until you hear it click. Then drive the car for at least 100 miles. If the light goes out that was the problem.
If the light stays on then you must take it in to be checked by special equipment because that is the only way to isolate the problem.
In my own experience of the light coming on 3 times, there were 3 different reasons: 1) loose gas cap, 2) bad catalytic converter needed replacing [the most expensive unless under warranty] and 3) a bad gas cap that needed replacing. After all 3 instances, the light went out.
I hope it's only a gas cap issue for you. Good luck.

My check engine light came on code P0446; dashboard says "check gas cap" i took it off retightened it and check engine light still on. I noticed that the metal flap for the gas nozzle is...


The metal flap should not trigger the sensor. Once you tighten the gas cap you should clear the code and see if it comes back. Otherwise it will take a while to go away.
If it does come back even though the gas cap is tight it could be the rubber seal around the gas cap replacing that can sometimes fix this issue also.

Engine check light comes on and stays on for awhile then goes off. Dometimes when I fill the gas tank the check engine light comes on. is something to do with the gas cap or the instrument lights.


IF IT COME ON EVERY TIME YOU GET GAS.GAS CAP HAS BAD SEAL IT MORE LIKELY YOUR PROBLEM BUT LET AUTO ZONE SCAN IT FREE TO SEE WHAT TROUBLE CODE YOU ARE GETTING.

Check engine light


Sorry your going to have to change the gas cap. You can try  spraying WD-40 to the rubber seal on the gas cap to get you some more months out of it, the seals get hard and don't seal any more. Good luck

Check engine light/gas cap will not stay tight.


Yes, the gas cap will cause the Check Engine Light to come on. Will set code P0441 if I remember correctly. It should be okay to drive it. If you would like to confirm the code, take the truck to an auto parts store like Autozone and have them hook up their scan tool and read the code. If its P0441 it will probably be something like EVAP or Evaporative system leak.

Its an easy enough fix while your there too, just pick up a new gas cap or you could pick up an OEM one from the dealership.

Make sure the gas cap is there and is fully tightened (it will click), a loss or missing cap will turn the check eng light on.
