"Service engine light soon" came on a couple days ago. Dropped by advance auto. Turns out it was a gas cap code. I hadn't touched that thing for about two weeks. Anyway good to know. Got new wipers in the process.
Just put a new $10 gas cap on it and clear the code. If it comes back on then take it to a repair shop for diagnostics.

there is probably a pressure sensor in the furl tank .......
It's sensing low fuel pressure at the injectors.
Always make sure you hear several clicks when you tighten your gas cap
I had same issue several weeks back and replaced gas cap TWICE to find out a emission hose had been displaced during gasket replacement . Repair shop was HONEST & said their error, so no charge on diagnosis testing both times
Nope, it's looking at vacuum in the tank, it uses it to draw vapors through the charcoal canister. In a Dodge it's called the NVLD.

Ok, my hose goes up and stops just short of top of the filler tube. It seems to have a cap or valve on the end. No way the hose is dry rotted, no cracks and flexes ok. I'll try a new cap next.

I had this light come on about 2 years ago when one of the kids left the cap off after a fill up. It didn't clear for several days after I put the cap back on. I bought a new cap, but the error finally decided to clear before I got it on. Hasn't been a problem since. I still have the new plug somewhere....:shrug:
What kind of truck do you have? I can't remember anything but your bike.
When you located the cap end of the tube did you trace it all the way back to its origin?
I just noticed it was your b-day, desertrat.
A quick note on evap codes. Like a lot of codes, they do have a natural reset process. Meaning that if you fix the condition, the system will see that, but wont erase the code right away, it will require a certain number of "drive cycles", which means a full warn up to operating temp, a shut down period of a certain amount of hours to let the car go full cold, rinse and repeat.
On the Neon, I think it was 8-10 cycles before it would reset.
Thanks. I have not driven much since I tightened cap and disconnected battery.
