5 codes and 16psi max boost?
 

P1693
P0382
P0236
P0230
P0112
New fass 150 map sensor iat sensor intercooler boots
Still no boost any ideas?

To find what the codes mean on the top menu bar (black bar just below the DB header) go to tools. When the drop menu drops down, select the OBD II Look-up. List the description for each code on the thread then we can start to help you out. By doing this you are helping us to help you.:tu:

P1693 companion engine control module has shown fault
Generic fault indicating a fault in the bus or pcm/ecm interface
P0382 intake air heater #2 control circuit
P0236 boost pressure sensor rationality
P0230 transfer pump circuit out of range (which I knew cause I had to wire my fass to a acc hot)
P0112 iat sensor circuit low voltage

Take the edge comp off the truck and clear the codes. See if they are still there.

Do you have a good lift pump (FASS or AIRDOG)?

I have tried with edge off won't clear fass 150 here's the thing the vp ran with no lift pump for who knows how long before I got it and fixed it . I want to believe its not the vp but most likely is right?

Update getting codes read and computer flashed and updated this friday will know diagnosis then hopefully

Turns out the dodge dealership here is full of booger eating idiots had it flashed andcodes read they got four codes I get five and still check engine light, no boost, no information on th:scare2:e 1693 companion code but at least they got their 105$. Any ideas out there or should I just replace the vp pump? :scare2:

VP is not the issue. Sounds to me like you've got something electrical, open wire, bad ground or something. Dodge was sure the ECM is good? I thought they tell everybody their ECM is bad :D :D

Start cleaning grounds, check all wires for frays or wear from rubbing. Start at the batteries and chase them wires.

Take it to an independent shop that knows what they're doing. You can't diagnose issues like this over the forums. Most dodge places have one good diesel tech that's staying current with each newer truck. Not to mention, they have swap parts in stock. They really never do true diagnoses anymore lol j/k dodge techs

Any wires inparticular or just all wire. I was going to take it to a shop here in town I just hate someone else figuring it out before I do. Stinking electronics anyway. Not sure if I said it or not but it fuels hard till about 16psi then falls off if done right I can get 20psi. Thanks for any help ideas or otherwise

Re: 5 codes and 16psi max boost?
 

Could be an internal ecm fault, could be an internal pump fault, could be a wiring fault. Without data logging the truck and multiple reset/run cycles with the codes it will be difficult to pinpoint the problem. It could be wiring but wiring is typically a intermittent problem. A biased sensor that is ranging out to early could also cause it. I would check map in voltages, map sensor signal voltage and verify voltage climb until the problem occurs to verify the sensor isn't causing default. The rationality code is rarely a low boost issue but a sensor issue.

I think im going to get with my local shop (addicted diesel) and see about data logging. I just put a new map sensor in not that long ago and when i flash the computer the codes never erase? Ecm is what me and a couple guys are thinking who you get a replacement from if it is bad

Re: 5 codes and 16psi max boost?
 

The ecm could com from cummins or any auto computer supply shop.
I'm voting that your not able to clear hard or ecm codes with your tool. If you are its a constant fault. Once the data is viewed and or logged for the map sensor (which can be done by any reputable auto shop, not just performance shops) you can make a determination of the issue. Often issues like this are caused by boxes that utilize the map sensor via jumper harnesses. But again, until the data is available, its impossible to diagnose this problem. Don't just go throwing a ecm because it might be it.
Heck, go to any shop and give them 1 hour of shop labor, ask what voltage are for the map sensor according to their scan tool. Then verify the voltages at the sensor

I have the edge comp on 5x5 what should the voltage be at the map

Re: 5 codes and 16psi max boost?
 

Unhook the edge from the map sensor, or completely disconnect the edge (don't worry about the tap wire) and see if the codes will clear. The sensor supply voltage should be 5v and the signal should indicate 0psi of boost and follow with the increase of boost. Can't remember exact voltages but try the edge first and I'll look the voltages up if you need them. The voltages are more important as in the sensor indicates psi of boost. In other words if 3.78 volts = 20 psi to the computer, yet the sensor shows 4.89 volts at 20 psi the truck will defuel because the computer sees a higher boost number than is actually present.
Hope that makes sense

I have unplugged the box mlre than one once to clear it and it won't clear even without the box

1693 is a comman code dnt worry about it

I have also heard that it can be hiding fatal vp codes :argh:

Re: 5 codes and 16psi max boost?
 

It's a companion code which indicates that a mil request set from ecm. That's the reason you need a decent scan tool.

nope iv heard tht too im almost finshed up wit diesel tec school and don been threw the codes its nothin at all

Re: 5 codes and 16psi max boost?
 

Ps that companion code set because of the map sensor out of range. You will need to do further diagnoses of the map circuit if removing the edge doesn't change the out come. I recommend before jumping head over in this diagnoses that your up to it. With what you have described you either have an internal ecm fault or your wiring is faulted between the map sensor and ecm. If you need help just shoot me a pm

Thank you guys for your help. How come when I took it to the dealer to erase codes did it not erase edge was off new map new ait sensor did it either not erase or threw em right away with no edge and my fass running off the lift pump curcuit but still had code saying it wasnt working :s:

Re: 5 codes and 16psi max boost?
 

May very well be a failed ecm, bad ground but it could also be a daily that's continually out of range. You really need a scan tool that will read data to go any further

I may just get a donor and p-pump it and spend good money and not after bad o

Re: 5 codes and 16psi max boost?
 

I would just take it to a good shop and fix the problem. No reason to spend 8k if you don't need to. It's actually a very simple repair with the data and tools required. If you were closer I would tell you to bring it in.

It will be p pumped eventually. I think I may have to drive three hours to get it fixed anyway. Im just trying to avlid the drive

Got it fixed was a combination of things. Fueling hard to 32psi just need big single and studs :c:
