P Codes after M1 Install HELP

701 Views 7 Replies 4 Participants Last post by  BlackDragon
Today I installed the M1 intake on my 2000 Durango R/T. I thought everything went well, until I ran it. I added coolant and let the enging idle to warm it up. But the temp guage remained below scale... even after I realized it was overheating! :shock: The P codes I got from the PCM are P0505 - Idle control system malfunction. And P0118 Engine coolant temperature circuit high input.
Now I think I might know why I got the temperature code. I replaced the cooling temp sensor and I think I screwed up the connector. I'm gonna get a new one tomorrow and see if that does it.
My main question is the P0505 code. Is this normal after an M1 install? What exactly does it mean and how do I fix it?

It is not normal... did you get an EGR one or NON-EGR ?

Turtle ?

If you got an EGR one for a NON-EGR truck.. did you plug the holes correctly at the back ?

Something is wrong that is for sure.

I got the non- EGR version. Part no. 5007852 with no turtle. The truck did idle a little high but I figured it just needed to let the PCM adjust for the new air carachteristics.
Guess not. I'll have to try and figure it out.
Try doing a search. I have a seen a list of the fault codes somewhere on here. You should be able to find out what it is. Also what you may want to do is just unhook the battery and try reseting the computer and see if that makes it go away.
I found out what the P code is. But it's pretty vague. No idea where to start.
P0505 - Idle Control System Malfunction

That gives me no clue where to start.
I had a similar problem when I installed mine. You have to extend the wires that connect to the manifold air temp sensor, and I reversed the wires when I extended them. Once I fixed the wiring, and reset the code I had no more issues.
Well, I solved one problem... I forgot to reconnect the Idle speed air control motor on the TB. DUH!!! :roll:
I checked the voltage coming from the coolent temperature sensor and got no voltage with the engine running at operating temp. What should the voltage be?

I'm still trying to find a replacement connector for that wiring since mine fell apart. Nowhere in town has one. So I'm off to Houston soon.
Well, I finally found a connector.I had to drive to Silsbee to get one. That's about an hour and a half from my house. Seems that none of the salvage yards in Houston have Dodge trucks in them. Thankfully, this place deals only in trucks and vans. He had at least 100 late model Rams. So, if you live in Houston or Beaumont and need parts off a salvaged Ram go to Armour J Salvage.

I installed the new connector and the Durango is running great! I didn't notice much change in power for taking off from a stand still. But it sure seems to have more when I go to pass someone. I think I'll keep it. Also, I've noticed an increase in gas milage. Up from 10.5 to 12mpg. Not much, but every little bit helps.

Thanks for all the suggestions and advise guys.
