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

Mechanic said I had no leaks after smoke test. he checked the current to the nvld and said there was none. I just changed the nvld purchased at Auto Zone a week ago.do i need to trace the wires to look for a short that seem pretty well wrapped up so a broken wire doesn't seem to me to be the problem. does the nvld have a fuse attached to it?

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

Bad ground is only solution !

SOURCE: blower motor will not work

Do further tests at the relay to ascertain whether the fault lies before or after the relay.
Check power availability at the supply side of the relay contacts - should have 12v from a supply fuse on one side of the normally open contact (note -this supply may only be available when Ign or Acc sw is on).
If power supply is ok at the relay contact, check control input to relay operate coil.

If a ground (or 12v) operates the relay, operate the relay with a local ground (or 12v) and check blower motor runs.

If all above OK, check control signal from fan switch is arriving at the relay control coil.- if not trace wiring back to the switch.

SOURCE: doesn,t start

If you notice that your gauges do not move (i.e. gas gauage) when you turn the key to the on posistion... it is cracks on the back of the dashboard instrument panel. My vehicle would ocaissionally not start (super frustrating!!!) and I'd wait an hour or a day and it was fine. Best way to check is to smack the glass in front of the instrument panel. That was my litmus test. 10 months later and an hour taking the dash apart i found the cracked solder spots, i resolered them put it bak together and no proble for the past two months!!! This is a huge problem with Dodge...

SOURCE: 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

I have have a 2003 dodge durango and I have had a smoke test done with no leaks the mechanic said it has no power to the NVLD how do I check this


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.

How much will it cost to fix codes po551, po442, and po455. I am having these problems in my 2001 dodge durango


two of the codes are EVAP codes. The cost of the repair could be $20 or it could be up to $1200 dollars or more. It just depends on what they find. It could be as simple as a cracked hose or it could be something a little more sever like a NVLD pump or a charcoal canister.

The P0551 is a power steering switch code, i think.

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...

2003 durango brake lights stopped working


Something is being missed,start with checking the fuse for the brake lights. Then check the brake light switch for power in and out(when depressed).Your ground is intact so no power. If still nothing, remove the lamp in question and test the contacts. good luck. Don't forget to depress brake pedal while probing contacts.
