2010 jgc limited/ v8 hemi

Hi! I am reaching out for help on a problem we have had for a year or more. We need advice on what to do and where to look for the problem. We have the model stated above in the title. It has been giving us a “check gas cap” message and a check engine light for a year now. We have changed the gas cap and a canister thing (cillinoid) (spelling is probably wrong). Anyway, it won’t go away. Where do we go from here?

We live overseas and most mechanics do not work on American vehicles. We have two options on mechanics. What do I tell them to look for? We are lost. Help!

The system is the EVAP (evaporative) emissions, They are called the gas cap codes. The gas cap is part of the system and always first thing to check. Basically it is a gas fume containment system.

The system runs from engine to vapor canister to gas tank. there ae several valves, solenoids and a considerable amount of tubing.

When an issue like yours the standard trade practice is to get codes as they will narrow the search area, A 'smoke' machine is also used to pressurize the system with a visible 'smoke' a tracer to help technician localize where leak is located.

You should watch attached video to see if you can get code.

The system is common across late model brands.
Your location may not have jeep but maybe something else comparable..
Let us know if you need more info -

PS 'solenoid'

When I see the price of OEM I think aftermarket.
When I see the quality of aftermarket I think OEM.

Please tell me you got a laugh out of my failed attempt to spell that 😂.

Anyway, I will do this in the morning and see what it tells me.

We had a code read done last week for the 40th time. They stopped charging us for them.. because we are frequent flyers 🙄😂. Also, they just wanna figure this out too. They want to look at it and look at the whole thing.. but in my mind that’s frightening in regards to expenses.

The code read came back clear. My husband did a reset and it went away for a day.

We will see what this trick does! I will update soon!

The majority of the evaporative control system is located under the rear fender behind the driver's side rear wheel.

Check all hoses and connections carefully for cracks & leaks around the components.

Also, check the tubing that runs forward to the solenoid valve in the engine compartment. The connection from the solenoid into the intake manifold is easily dislodged. Verify it remains connected or add a hose clamp to keep it there.
