The major of the EGR related problem are carbon build up and leaky rubber hose.

====

There are carbon built up INSIDE the small tube between the exhaust manifold and the EGR valve.

Soak the tube with WD-40 or PB Blaster overnight. Use a 22 gun cleaning kit to remove carbon from this tube.

Install new EGR base gasket to ensure there is no exhaust leak.

====

Checking EGR plastic tube/hose leak will take some time.

Professional use a smoke machine to locate leak(s) quickly.

Carefully move the hoses around and look for small cracks.

Tighten all hoses.

====

Reset the code and test drive the van.

Gas Cap light doesn't always mean that was the problem

Check engine light 2007 dodge grand caravan


Most common problem is a loose or defective gas cap. If it is not tightened properly it can set a code.
Once you tighten or replace the cap, the light should go out after about 100 miles of driving.
You can check engine codes using a free loaner scanner at Autozone parts store, etc.

Good luck, Gary

Check Engine Light won't go off


If you have an Advance Auto Parts store where ever you are, they will read the code and tell you exactly what to code is and what it means. Any mechanic who "guesses" isn't a mechanic at all - he's a thief. Emissions leak can be any number of things, but not the gas cap!
