Question about 2005 Dodge Neon SXT
Didn't come on until after 500 miles driven after the installation of the kit, we tried everything and it still comes with the EVAP purge flow code 0441 and I don't understand where it is coming from I have a locking gas cap on the car but the car has had that on for over a year now, can anyone give me any ideas about what it might be?
DTC P0441 - Evap. Emission System Incorrect Purge Flow
Possible causes: poor/loose connection, faulty purge control solenoid valve (PCSV), faulty PCM.
Check for loose electrical connector and for loose or broke vacuum hose to it. If ok, you will need a voltmeter and vacuum gauge to test it. If fails test, replace it, if ok, then likely a faulty pcm. Most of the time it is either a bad vacuum hose to it or faulty PCSV.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.

SOURCE: Dodge Neon code 1494
p1494 isnt for the purge solenoid it is for a mechanical switch failure detected in the leak detection pump. as long as the pump has vacuum going to it the likely cause is the pump itself. it is attached to the vapor canister

fuel cap is just one of the causes. Here are 2 others:

Here is what I could find for your code error as potential causes:
After market parts and accessories nonconforming to the EVAP system specifications.
Damaged, missing or improperly installed fuel filler cap.
Blockage in fuel vapor hoses/tubes (EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube) in EVAP system.
Disconnected or cracked fuel vapor hoses/tubes in EVAP system.
EVAP canister purge valve stuck closed.
Canister vent (CV) solenoid stuck open.
Fuel tank pressure (FTP) sensor malfunction.
EVAP canister leaking.
Fuel vapor control valve tube assembly blocked.
Fuel vapor vent valve assembly blocked.
Obviously the gas cap would be the easiest and cheapest thing to fix. Just make sure it is put on correctly and tight. If it is not that, I would have to suggest to take it to a mechanic because the other problems on that list are not really DIY material. Hopefully it is the gas cap and you can take care of it yourself. Good luck.

The P0441 shouldn't cause a no start it is indicating there is a problem in the evap system related to the EVAP solenoid, EVAP solenoid vacuum supply or the NVLD switch which is a switch that vents the tank at proper times. I would do a fuel pressure check if it starts at times with carb cleaner. there may be a small leak in the evap system that a qualified shop with a smoke machine should be able to check out, but that code shouldn't be the cause of your no start. When first started it needs the proper fuel pressure and will normally run fine once it's started until the pump degrades to a spot that it just won't run correctly any more. the computer on today's cars can compensate for a lot of things to a certain point till they just won't run anymore.
