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.
