Check engine light has been on for a while now, throwing codes P0442 (Evaporative Emission Control System Leak Detected (small leak) and P0455 (Evaporative Emission Control System Leak Detected (gross leak).

From what I've gathered from the forum, these problems can be extremely difficult to trace and have virtually no impact on drive-ability and/or gas mileage - but PLEASE correct me if my assumptions are incorrect. So, my question is: What would you do? Take it to the shop? Let it go? Something else?

Thoughts and/or tips greatly appreciated.

Thanks!

I'd have to fix it. I can't stand looking at the cel. Find a shop that can smoke test it. They should be able to find the leak. Last vehicle that we sold (Chrysler Town & Country) had a problem like that and it was the gas cap that was bad.

I'm on gas cap number two, so I would guess that it's not the culprit.

I would get another gas cap just to rule out that your 2nd gas cap is not the culprit. It's a cheap fix. Better yet, if you have another fellow buddy tha owns a durango, borrow his to see if your CEL goes away to confirm your problem.

What do the vacuum hoses look like, what/where are they connected to, and how do I check them?

Thanks again.

they are the small hoses that have the little capped thing on it that says something about 1 psi, on my dads truck one of those hoses(they also go into the intake hat) was cracked and we just cut off the cracked part and put it back together

it would help to know which motor & year you have, I'd get a manual and start looking at all of the vaccum lines related to the evap canister, & the line(s) going back to the tank. you probably have one that has cracked causing your CEL to go on.
