Looking for 3 engine codes

p0441
p0455
p1448
I failed the IL state emission test and I have to get these 3 codes fixed. Nothing comes up anywhere. I called a couple local shops and they told me to bring it in.

All are EVAP stuff:

441 - can't find this one but all the 4nn 's are EVAP
455 - Evap control system gross leak
1448 - Evap Emissions Canister

I checked all the lines coming out of the canister and nothing seems broke Is there a way to check it to see if its bad?

Check the FSM for your year.

P0441 is Evap Purge Flow Monitor

Looks like you've got a canister that's come apart. Check at the purge valve in the engine compartment, on the driver's fenderwell. If you pull the line off and charcoal comes out of it, you need to replace the canister and try to clean all the valves out by hotwiring them and blowing through them. Simple batter voltage will activate the purge valve. The blow it out as best as possible. May take a couple of tries. Otherwise you'll have to buy new valves (purge volume control valve and vent control valve on the canister).

You may have to get a new vent control valve anyway if it doesn't seal when you activate it.

Fuel cap tight? If it don't build pressure in the fuel tank the vapors never make it to the canister.

Loose gas cap won't throw a purge flow monitor code. That will throw either a gross or leak detected code.
