The check gas cap light was in response to complaints of the check engine light being on for loose/missing gas caps. So now when the PCM sees a large EVAP leak the first thing it does is illuminate the check gas cap light (on models equipped with the light). Since it doesn't know if the gas cap is on or not it can have other issues like a vent solenoid stuck open which the PCM would be unable to distinguish between that and the gas cap left off.

There will still be a trouble code in the PCM for the EVAP system.

An easy fix, if the check engine light is on find an Auto Advance, they can clear the code for you. Any auto parts store may be able to as well, Auto Zone is another one that may be able to help.

SOURCE: Check engine light/gas cap will not stay tight.

yes the gas cap could cause this,also check evap. purge solenoid and hoses for cracks or kinks,the solenoid is on the inner fender and has 2 hoses, one to the intake and one to the canister, the most common cause of this code is a defective purge solenoid.

yes the light is because of the gas cap being gone (sets code in evaporative emissions system), replace the gas cap, disconnect the battery for five minutes and that will turn of/reset the light, make sure u have the radio code before u do this, if u don't u will have no radio after the battery is disconnected..

Take the car back to your Mechanic and have the mechanic reset your system. Some may advise you to disconnect the battery, and that will reset your computer. This may cause significant problems with your car's computer,radio, alarm. Take the car to the mechanic.

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 have a 2000 dodge dakota quad cab (4.7L / V*). My check engine light kept coming on after tightening the loose gas cap. I purchases a new gas cap specifically for my truck and the light came on again...


Check that there are no other leaks in the gas filler neck or gas tank itself that would cause the gas cap error to cause the check engine light to go on.

A lack of pressure in the tank can cause the check engine light to go on, erroneously signalling that the gas cap is loose or missing.

Good luck on this repair.

If you allready checked the gas cap and its on right.
Try replacing the gas cap with a new one.

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 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.

Check engine light comes on if gas cap is loose (according to the dealer) - not really wanting to go back to the dealer repeatedly for a quick fix to turn off the light, but not wanting to ignore the check...


replace the gas cap .. clean the gas filler pipe where it seals against the gas cap .. .. even a small crack in the rubber seal will trigger the check engine light ..

Fuel/gas cap


have you replaced the gas cap? most of the time when a check engine light is on for the gas cap, its because the cap isnt venting the fumes properly or the cap isnt on tight enough.

Check engine light on


I had the same problem. I went to the kia dealer and they checked the code that caused the light to be on and found I had a leak in the gas cap. They replaced the gas cap and the problem went away. You night need to find out what made the check engine light go on in the first place.
