Get this. I start inspecting the hoses of the evap system and trace them up into the engine bay. They all look fine. no cracks, and still pliable.
Hmmm I notice there's a grommet in the drivers side valve cover with nothing in it. There's also a hose coming from the intake to that general area. Looks like something is missing.
God up to dealer and find the PCV valve is supposed to be there! buy one and pop it in.
Dealer says that a missing PCV valve wouldn't kick up that code. Huh? They wouldn't clear the code either, unless I payed $85 to hook up their scanner.
No thanks. Called the other Chrysler dealer up the road where we bought it, and they said bring it in. We'll look at it.
Wife stopped by Sears where she gets her oil changed and they cleared the code no charge. We also put her original gas cap back on in case the aftermarket locking cap was causing problems.
Still going to take it to the dealer. While under the Durango, I noticed way more oil on the underside of the oil and tranny pans than I'd like to see on a 60k mile vehicle. It is leaving small drips in the driveway.
I thought they were from the rare occasion I park my 17 year old bronco in her spot.
I'm going to see if they'll replace the gaskets that are leaking under warranty.
wish me luck.

 

On my 99 that driver side grommet is for an elbow that has a hose from the valve cover to the airhat on the throttle body..the intake line is plugged off on the driverside and the pcv valve is on the passenger side and runs to the intake port on the passenger side.I'm not sure if that's the same for the 03...

 

Try Autzone or Advanced auto parts =they can reset the light and scan it for you too=free...Make sure you go to a reputable shop for that oil leak so they don't snooker you into a rear main seal when it could be an oil pan gasket..So that pcv enhancer=a Mr.gasket clear view gas line filter=to keep oil from get sucked in a smoggin the o2's?

 

Dragonofmadness. Is yours the 5.9liter? The PCV valve I got fits perfectly, and there was no sign that this hose was ever plugged. I'd think they'd have put a cap on the lin on the manifold or something. there was another elbow for something with a hose going to something on the passenger side that seemed intact. It didn't look like a PCV valve. just a plastic elbow.
On the same note, the dealers pictures in his computer sucked royally.

 

if you don't have a obd2, I think the only thing you can try is pulling the neg cable and turn your key to on for 30 seconds. if it doesn't clear, you still have repairs to do.. good luck

 

I can speak for A/Z not resetting. They started not doing that..... Is that proper terminology.... well you get the idea, last year. They will read, print, advise of codes and even sell parts or offer construcive suggestions on replacement but will not clear codes. Advance has followed suit. I moved to Northern VA recently, and they have even gone so far as to not even help. They will loan the obd scanner, if you leave a license and work in the visual range of the parking lot, but I guess what they dont know wont hurt right?

 

just do the battery removale if no one helps.

 

I believe the 5.9 is the sister to the 5.2 ...My pcv is on the passenger side and there's a hose on the driver side that goes to the airhat from the vavlecover

 

It might be a little soon for a long term report, but I had a P0456, EVAP VERY SMALL LEAK DETECTED. I checked code, cleared and this might be something to try. I put a extra o-ring on my cap. I put it on the cap, just above the threads, wider than the filler neck, but below the stem of the cap. Basically another seal between the filler neck and the cap. Again might be a little soon and I hope I am not jinxing myself but so far so good. Light cleared, computer reset and hopefully this will be a fix. Total cost about $2-3 dollars for o-ring.

IF you need further pm me or e-mail me at maineiac88@yahoo.com and I will send photos.

 

Here is instructions on how to reset your computer manually without a scaner.

Engine Code Index (Check Engine Light?)

2000 and newer Durangos have a built-in system that can display check engine light (CEL) codes without the use of a scanner. 1999 and earlier Durangos must be read with a OBD-ll scanner. Your local auto parts store will usually do this for free.

2000 and newer directions:
Turn the key to ON (not start), OFF, ON, OFF, ON and leave it there. If you look in the odometer window the codes will flash any code(s) with a small delay between each result. Each code should be in a P#### format, and will say PDONE when completed - turn your key to OFF and remove. Use the OBD code list to determine what problem the computer detected.

To reset your engine codes:
Remove the negative terminal of your battery (10mm wrench).
Turn your ignition key to START and hold it there for about 15 seconds.
Turn your ignition key to OFF and remove it.
Connect the negative terminal of your battery.
Start but do not hit the throttle. Idle for about 10/15 seconds then turn off.
Restart the truck and drive as usual. It will take at least 12 starts and 48 miles to fully retune the computer. Hard Codes leave a shaddow for 40 full cold starts.
