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

Put a K&N Performance Cold Air intake into my 2005 Dodge Neon SXT, 0441 code comes up?


Hi there:
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.

Engine light on diagnosed PO44O dodge said probably the purge control solonoid. where is this located on a 2004 dodge neon?


Try checking the gas cap first off. 95% of the time, an EVAP code, (purge solenoids, or any EVAP code) could be caused by a lose gas cap, or a defective gas cap.

And I know on SOME neons, the evap canister purge solenoid is located on a bracket attached to the air cleaner. Hope this helped.

Dodge neon code p0456


What does that mean? The Powertrain Control Module (PCM) at different times performs various tests on the EVAP system. OBD II Enhanced EVAP systems are in place to keep fuel tank vapors from venting into the atmosphere, and instead purges them into the engine to be burned. Regular pressure tests are conducted by the PCM to monitor the sealed system for leaks. The PCM monitors the EVAP system pressure by watching the fuel tank pressure (FTP) sensor. When the sensor indicates a small leak in the EVAP system, this code is set.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook Potential Symptoms There will likely be no noticeable symptoms other than the Malfunction Indicator Lamp (MIL). This is because the EVAP system is a closed system and only controls fuel tank vapors, not engine management.
Causes Usually this P0456 code is caused by an incorrect or faulty gas cap. Filling the fuel tank2_bing.gif with the engine running could conceivable cause this code as well or if the cap wasn't properly tightened. Any of the following could also be the cause:
  • A small leak in any of the EVAP hoses or fuel2_bing.gif tank hoses
  • A small leak in the purge valve or vent valve
  • The EVAP Canister may be leaking
Possible Solutions First, using a scan tool activate the vent solenoid, sealing the system. Then monitor the fuel tank pressure (FTP) sensor. If the system is sealing properly, the number will stay consistent. If is isn't, the pressure sensor will show that as well. If the system slowly leaks, use a smoke machine and watch for smoke exiting the system at any EVAP component. Any where there is smoke exiting the system, that is the faulty component. Do not pressurize the EVAP system with air pressure. Doing so can damage the purge and vent solenoids in the system.

MY 2002 NEON HAS 2 CODES P0442 AND P0455 I HAVE CHANGED THE FUEL CAP BUT STILL KEEP COMING BACK


both those codes point towards evap system leak, p0442 being a small leak and p0455 being no purge or large leak, check the charcoal canister and linds attached to it for holes.

Im getting a P0441 EVAP emission control system purge flow fault code on my 2002 dodge neon


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.

What is code 1494 mean for 2001 dodge neon


P1494 Leak Detection Pump Switch or Mechanical Fault
Part of the early evaporative emission system. (Fuel tank fumes)

It’s there to allow the computer to run an integrity test of the fuel tank, lines and carbon canister’s ability to contain all of the fumes coming from the tank and all line associated with the system.
The code could be set for a number of reasons such as a faulty gas cap, cracked vacuum lines, solenoids & vent valves stuck to the pump itself.
It can be a very difficult fault to cure being it doesn’t take a very big leak anywhere in the system to set the code and that’s if it’s a leak and not an electrical or mechanical fault.
