I don't have a manual for your car and have never even looked under the hood of an ION, so I'm not sure. They're usually stuffed up under a fender or near a fender towards the front of the car. Surely someone else here that works on them can either point you to it or post a picture?

P0446 EVAP Vent Solenoid Valve Control System
Has to do with capturing gas vapors when you fill your tank from directly entering the atmosphere. There are several solenoids (switches) that the control when and where the vapors go.
The problem could be a defective solenoid (there are several in the system) or I have read that people have had a bad fuel pressure sensor throw this code.
Others get this code, then clear it, then it doesn't come back for months.
If you are not having problems filling your tank (pump shutting off), just get the code cleared and see if it comes back.
Even if it comes back, if there are no driveability or gas pumping issues I'd let this one slide for a while.
As for location of solenoids -- no clue on an Ion. Maybe Rj knows. Prob near the gas tank.
So just get the code erased at autozone and see if it comes back

My car has no issue which is what is annoying the fuc* out of me. My gas mileage hasnt changed, my car drives normally, my car fills up with gas no problem. Guess I'll just try clearing the code. I dont have $$ to be replacing stuff for no reason lol
The car places around here wont clear codes because there was a big thing of people getting the codes cleared and selling the cars. I'll see if a friend has a code reader who will do it for me.

Here are a couple of pictures of the evap canister and solenoid-the canister is at the rear of the car behind the fuel tank. I've highlighted it on one picture. The solenoid is located at the driver's side of the engine-I've highlighted it in the other picture.Attachment 660

Hope this helps- I do have a whole diagnostic procedure available if you need it.
Good luck!

I'm kind of with derf and Charlie on this one- I'd kind of slide on it if you can. According to my Alldata, the code will go away if the car starts three consecutive times with no issue. That's the cheap way to do it! I'm kind of suspicious of that cap too, since that could affect the pressure of the tank vapors...

What do you mean 3 consecutive times? Like turn it on let it run a second turn it off and then back on? Or like 3 trips?
I was having an issue with my cap a few months ago...i for some reason couldn't get it to lock on right and I'd be driving and I would get a message on my dash saying check gas cap...but I haven't had that happen in quite some time. IDK...maybe my cap is the problem....I'll call the dealer and see how much one costs.
