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...

SOURCE: check engine light code PO456

most likely the pressure sensor in the fuel tank for the evap system is defective.

SOURCE: 2008 jeep patriot engine light is on

I would have it scanned by an auto parts store, to see what the code says, then get a service manual, cheap ones are at promanuals.net

SOURCE: 2006 Jeep Liberty sporatice warning signals

I had the same problem with my 2006 Jeep Liberty Renegade. I shared with the Jeep service tech what I found on the internet regarding this problem. I was having the gas cap sensor to display and soon after other sensors were lighting and dinging and some times dinging without any indicator and vice versa. the service tech said he was not aware of any such complaints and recommended a diagnostic which found no trouble codes and recommended to change to the gas cap. I did so and no sooner than paying almost $100 for the service and returning home the same thing started happening again. I returned my vehicle and they called the Chrysler/Jeep service tech who obviously was aware of these complaints [Service Bulletin #14-001-06] and recommended the following: A complete system reboot. Disconnect the battery cables and short together for 15 seconds. If message returns then the problem may be with cluster. I have not had any dinging or gas-cap sensor display since this was done.

SOURCE: check engine light, vapor canister, have any idea

I would start with the gas cap replacement and see if the issue resolves itself. If you do have a problem with the EVAP (canister) system, it may require tools the average person does not have to help diagnose and correct/repair.

If the cap is good and the venting system is working properly the code should re-set itself in about twenty miles of driving.

Check all vacuum hoses at the fuel tank for damage or dry rot and make sure your gas cap is tight.

2009 jeep patriot. the check engine light cam on took it to auto zone and they said it was a gas cap. they fiddled with it and shut the code off. i drove it less then 10 miles and it is back on.


Did you replace the gas cap? A gas cap that does not seal properly will allow air to be drawn into the evap system and will give you a corresponding check engine light and code. Caps are relatively inexpensive, so buy one and replace your old one.

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 indicator keeps coming on after replacing the gascap - now the engine light is on. I had codes reset but situation continues.


this will keep happening until the problem is fixxed, theres an evap system leak, the cap light comes on because most of the time its a cap ,but not yours, the system needs checking you may have a bad valve or broken vacuum line for the evap system, this system has lines running from gas tank to engine with valves and soleniods and it everything is not working or the system cant hold vacuum it will turn on the light, a smoke machine is need to test the system and find the leak, hope this is helpful.

Gascap light comes on everytime i start up the car


I had this similar problem but gascap and engine light on. I changed out the gas cap cleared codes and both were back o. Went to the dealer he insisted it was the after market gascap changed in and cleared the codes. Before I even left the lot they were both back on. Finally they found the problem they had to change out some kind of pump and canister and it fixed the problem.
