It might take 2 or 3 gas fill-ups before the light goes off. Don't worry.

SOURCE: how to shut off gascap light chrsler aspen

You may have a faulty gas cap. If you are tightening the cap down securely the light will go off after the car is driven about 40 miles. I suggest installing a new gas cap which should cost about $15 at your local auto parts store. *** Please rate me on this answer.***

What are the causes to look for once the engine check light comes on

something as simple as "Not Securely Fastening the GasCap" can turn on the check engine light. You have a fair amount of mileage on the vehicle (don't know what year make and model it is). Some vehicles may turn on the check engine or maintenance required light after a certain amount of mileage just to insure the systems are checked.
Your best bet is to have someone scan the fault code to determine what to do next - there are numerous issues that can turn on the Check Engine Light. A local Auto Parts Store will probably scan the codes for Free.

Gas cap light came in jeep patriot 2008

Start by rebooting the as explained regkyl.
If issue returns then get a new gascap and reboot again. The seal on your cap is maybe worn out.
If issue still return then you'll have no choice to go and have the sensor checked and hope the problem is not with the cluster...

Check engine light on

Try tightening the gascap. Go to an Autozone, Advance, or Oreilys parts store. They will give a free scan and it probably will show that there is an Evaporative emissions system leak. A leaky gascap can generate this Code.

Engine light on & gascap

The gascap light means you may not have the gas cap on tight, or it may be faulty. The check engine light means the computer has found a problem that will affect performance and-or emissions.
Such as a leaking gas cap.
If the gas cap is ok, you may need to get the computer scanned for trouble codes to proceed with testing.

Check engine with error codes P1111 and P0455

The Code 455 is showing the large leak in the Evaporative system (gascap) and the Code 1111 shows there are no defects.

You can get these codes wiped off with a scanner free at Autozone, Oreilys, or Advance. They may clear by themselves after 35 startups.

It would just appear to be a latent record of the old condition before and after you tightened the gascap.

My service engine soon light came on checked the code it said something about the evap system ?

There are a couple of different issues on this.

First off, the actual cel (check engine light) code would be extremely helpful it will be Pxxxx

Other than that, a general troubleshooting guide would be to check your gascap.
Remove the gascap, check for cracks in the rubber seal
Check for dents etc on the gas filler neck which would prevent a good seal
Reinstall the gascap ensuring it clicks a minimum of 3 clicks
If this is your problem, your code should go away in a few days. If you find problems with the gascap or filler neck, etc. then go ahead and repair them. This is the most common cause of evap issues.

The other issue i have seen with the evap system on a '01 blazer is the pressure sensor on the fuel pump going bad. Good news is that this part is roughly $40 dollars. Bad news is you may have to drop the fuel tank to get to it since it's mounted on the fuel pump most of the time, and the fuel pump is on the top middle(ish) of the fuel tank. I don't recommend dropping the fuel tank full. It'll weigh a lot. (28 gal x 6.1 lbs) + tank ~75 lbs.

I took my Aspen07 to the shop and they replaced the gascap with a factory gascap, cleared the codes and the gascap message is still on as well as the check engine light. Any suggestions?

the check engine light is most likely evap system large leak which is what causes the gas cap light it probably needs a nvld pump or it has a leaking evap tube under th vehicle.

Gascap light comes on every time I start the car.

You will need to get the code befoe anyone can begin to diagnose this, There are about 5 parts that can cause this problems. The gas cap is one of them. If anyone has been uner the hood just pryor to this happening its possible they left a vacuum hose off or maybe broke one.

If this car is really an 07 then this being an emission issue you are covered under warrenty. Take it to the dealer.
