Hello, Yes you can set a code in your computer if the gas cap is loose. Plus do not fill with gas with the engine running or key on as this will set an evaporative emissions code. Thank you

Some body stolen the fuel gas cap frome my car,i drive 2 day w/out cap.when i see that im buy new gas cap,but tha chek engine come in on,what can i do to solve this problem?thanks


One of the problems that trigger a check engine light is either a faulty gas cap, gas cap not on all the way or no gas cap. Once you replace the gas cap you should be able to reset your check engine light or it may automatically adjust itself.

I'm getting gascap error and check engine light. What's causing the issue?


If you allready checked the gas cap and its on right.
Try replacing the gas cap with a new one.
You should here air wen you open the gas cap after driving
This is part of the emision controls and if it dosn't seal it will cause the check engine light to come on .

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.

Engine check light is on what i can i do


Most of the time Check engine light will come due to Gas and gas cap issues. If you ran out of gas and gas lost pressure it will bring the light on. Make sure to fill take with premium (91 octane) gas and make sure gas cap is closed completely. loose gas cap will cause the engine light to come on. If after doing this you still get the engine light warning, take to authorized mercedez deal for code check.

Gas Cap Error with Check Engine light


By "Replace the gas cap", do you mean put it back on, or buy another one? If you fuel these trucks with the engine running, or don't tighten the gas cap, the light will come on. It will also come on when the seal in your gas cap goes bad. I have had to replace the gas cap on my jeep and dodge already. It fixed the problem both times.

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.
