Hi Richard, I'm glad to help. The mechanic is the only one that can check power to the NVLD Pump because it must be actuated with the scan tool to check power. Check for a broken wires or a pin pust out on the NVLD connector. If you don't know what fuses to check then turn the key on and with a test light check all the fuses under the hood. If they are all good then you'll need it checked out further by a certified mechanic. If you do find a fuse blown and it turns out to be the one for the NVLD then replace the pump because its most likely the culprit that blew the fuse. Hope this helps and have an awesome day Richard.

SOURCE: 2003 Dodge Durango - How do I take off door panel

After you have removed the screws (one behind the door handle, you will see a little tab, pull it back to expose the screw) lift the panel and look behind it, there you will see (2) rods going to the door handle and lock. Use a small screw driver to pry the keepers away very gently. Pull the rods away from the keepers. Also, you may want to remove the panels from the arm rest and disconnect the wires from the control panel. I just replaced the window regulator for the second time.

2003 DURANGO NVLD NOT GETTING ANF POWER. COULD THERE BE A SHORT OR SOMETHING ELSE WHAT TO DO NEED HELP.


You need to go back to the shop & have them continue on
& test the evap system & nvld

You do not change parts based on codes or someone
telling you there is no power to a part

You were told there was no power to the part & the shop should have done the necessary testing to restore it

2004 dodge durango 5.7 hemi runs real rough white smoke comes out then blows oil cap off.


Ah oh..white smoke is water in the cylinder and cap blowing off is compressed air in the crank case..sounds like you have a blown head gasket or intake or both...have your radiator and block pressure tested..if gasket is leaking it will fail to hold pressure.. Check your oil for water sometimes a bad intake gasket will let water in the oil.good luck..

P0441 Code. Natural Vacuum Leak Detection (NVLD)?


Look at the following link. It definatly does make sence but possibly not the problem. Personaly I would probably start there after looking at the gas cap & hoses to the charhol canister. http://www.permoveo.ltd.uk/tabid/122/OBD-Error-Code/P0441/Diagnostics/Dodge/Default.aspx

P0440 code


Causes A code P0440 could mean one or more of the following has happened:
  • The gas cap is not installed or working properly
  • The purge solenoid has failed
  • The canister is plugged and not working properly
Possible Solutions With a P0440 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • Remove and reinstall the gas cap, clear the code, and drive for a day and see if the codes come back.
  • Inspect the EVAP system for cuts/holes in tubes/hoses
  • Inspect for damaged or disconnected hoses around the Evap purge solenoid
  • Check and/or replace the sensor
  • Check and/or replace the purge valve
  • Have a professional use a smoke machine to detect leaks

How do i replace the natural vacuum leak detection pump on a 2005 dodge dakota?


Vehicles equipped with NGC engine control modules use an NVLD pump and system. Vehicles equipped with JTEC engine control modules use a leak detection pump. Refer to Leak Detection Pump (LDP) for additional information.
The Natural Vacuum Leak Detection (NVLD) system is the next generation evaporative leak detection system that will first be used on vehicles equipped with the Next Generation Controller (NGC). This new system replaces the leak detection pump as the method of evaporative system leak detection. This is to detect a leak equivalent to a 0.020 (0.5 mm) hole. This system has the capability to detect holes of this size very dependably.


Removal & Installation
  1. Raise and support vehicle.
  2. Remove left-rear tire.
  3. Remove plastic shield (4) in front of left-rear tire. Access to both the EVAP canister (1) and NVLD pump (6) is from the area in front of the removed tire.
  4. Disconnect electrical connector at NVLD pump.
  5. Remove vapor line at NVLD pump. Pry outward on tab (3) and rotate pump (6) clockwise about 70 for removal.
  6. Remove NVLD pump O-ring (5) from EVAP canister (1).
To Install:
  1. Install new NVLD pump O-ring (5) to EVAP canister (1).
  2. Position NVLD pump (6) into EVAP canister (1).
  3. Rotate pump (6) until tab aligns with notch in EVAP canister (1).
  4. Carefully install vapor/vacuum lines to NVLD pump.
    WARNING The vapor/vacuum lines and hoses must be firmly connected. Check the vapor/vacuum lines at the NVLD pump, filter and EVAP canister purge solenoid for damage or leaks. If a leak is present, a Diagnostic Trouble Code (DTC) may be set.
  5. Connect electrical connector to pump.
  6. Install plastic shield in front of left-rear tire.
  7. Install left-rear tire.

Check engine light comes on


"po455 large leak" means that you are not maintaining positive pressure in your fuel system. Have a mechanic do a "smoke test" on the fuel system. Could be as simple as a loose gas cap...
