ok sorry about that this time i unhooked the comp completely the only code i got was p0122 as soon as the truck started, when pressing the pedal the truck would try to rev but just kinda drop off or let go but if i kinda feathered the pedal it would catch it again and rev like normal. and I just wanna say thank you for all the help you have been giving me, I appreciate your time

 

No problem at all.

Unfortunately, I think you looking at an APPS. Any warranty left on the one you put in?

 

hey im glad to hear apps and not vp44, I sent timbo an email to see what we can do, everyone has said he is a stand up guy so I hope we can work it out best for both of us, I dont know how long it'll take but i'll update this i soon as i replace the apps thank you again

 

Got the new apps, it didn't fix it, same code p0122. I just wanna say Timbo is the man, sent me a new apps free of charge no questions asked. I would recommend his apps to anyone in need of one. I'm going to send the first one back tomorrow and try something I found on Moparman1973.com. Here's the link APPS Sensor Error Codes If anybody knows something else to try I still appreciate all the help I can get. Thanks Casper

 

Have you tried replacing the map sensor??? i had the 236 code in mine and it was a bad sensor. It would work for a while then throw that code and de-fuel the engine so I couldn't make any boost!!!! sucks when your towing!!!!

 

is there a way to test the map sensor?

 

I lost power for over a month then one day the vp computer just Mia'd on me just like that and gave me the same symptoms as you described... But I threw start up fuel solenoid failure and Tdc code

Bit I did accidently leave my map sensor unplugged before and it did that so I would be leaning more towards the map sensor than anything in my opinion

 

You could try to unplug the plugs on the main harness on the firewall and plug them back in as well that might fix it for ya

 

after reading alot online and testing everything I could with a multimeter I was sure it was either the pcm or the vp44, so to be sure which one exactly I took it to the dodge stealership to have them look at it and tell me for sure what it was, now I didn't tell them any more than I have a dtc and I've replaced the apps that way they look over everything not just what I thought it was. the next day they called me and said, well it's either the pcm or the vp44, we would replace the vp44 and lift pump first and if that didnt work replace the pcm ecu and wiring harness. grand total for them to do the work $6,500. to keep from being banned from this forum I wont tell you my thoughts when they told me this. so in the end I paid $90 to be told what I already knew
