maybe i missed it, but what code does it keep throwing?? if we had that im sure it would help

otherwise i suggest that you check the wireharness for shorts/loose/bad grounds/frayed wires/corrosion and the likes

 

Yes I meant the Idle Air Control (IAC) valve.


If you keep getting the code then I would suggest that it is bad or the harness is corroded. Also clean the PCM harness that plugs in and reset the PCM:

Also we would like to see any and all codes that are present?

 

shrpshtr325 the only code it is throwing is "p0505" and that is the only code it is coming up with on my fiance's scanner. It will not stay running and wont run without applyting gas. and it cuts out.

hydrashocker- what harness would you suggest to check? and we have cleaned the plugs to the pcm but have not done the reset yet the way you listed. I will have him try that today.

someone also told me that when they replaced the pcm he had to replace cam position sensor, crank sensor, and MAP sensor. *it was on a jeep* after he replaced his pcm. could that also be the case?

 

i would check the wiring, follow the plug from the IAC motor to the PCM check for corrosion, loose connection, frayed wires and shorts

 

Check the main harness that plugs into the PCM on the passenger cab firewall under the hood. Also check the harness on the IAC itself to ensure a good connection.

As for replacing parts because you replaced the PCM, well there's nothing in the rule book about that one. I would assume that the person that did this to his truck (your friend) replaced parts until he finally found the bad part....LOL

 

OKay so i have yet to check wiring connections because i am having the same problem now as with the last pcm. It will not start. I will be checking the wiring connections today and let you know what i come up with.

Also, was wondering under my dash is a big clump of wires with fuses and they dont look stock. Any ideas on what they might be?

 

A picture might help?

Do you have an aftermarket security system?

 

it is a stock security system. I do not know how to upload pictures but i did take one.

 

SO my fiance is replacing the crankshaft sensor as i am typing this. hopefully this will finally solve my pain in my a** durango. I will let you know the outcome.

let me know how to post the picture of the wiring nest under the dash.

Thanks Guys
