24v vp-44 help with fixing circuit board
 

Hi I'm new to this site and am having trouble figuring out how to repair my vp-44 circuit board. I read a forum about it but I was wondering more about it. My truck is a 98.5 and I have dead pedal issues. Please help

You sure it's the vp? I had the same issue but it was my apps. Are you getting any codes?

I bought a new apps at autozone and put on and doing that is actually what made my check engine light come on, before installing my truck would have no power when cold then would warm up and take off.now I get dead pedal throughout driving and several codes at times like p0122,p0123 and others but don't remember at moment. Thank u for responding

I took the sensor out and returned it since it made my truck worse

Did you buy just the sensor? Or the whole bell crank assembly? Did you program the sensor to the truck when you installed it? Hope these questions don't offend you, just making sure to cover the bases.

Do you still have your old one available?

The one from autozone was just the sensor, I installed and did the throttle slowly down then back again? That's all I tryed and I put old one back in but it now acts worse? And I appreciate any help

You have to adjust the voltage on them and then do the throttle thing a few times. I would try a reset on your old one and see if that helps. Instructions on this link:

If this fixes your problem, then its the apps. Or it was for me anyway. I can shoot you a pm on some better places to buy a new apps sensor if it turns out to be that. Sure hope it is, as its obviously the cheaper fix.

In the meantime, maybe some of the more experienced will chime in here. You may want to post the stats on your truck while you wait. Mileage? Mods? Any other noticeable problems from the truck leading up to the dead pedal?

My truck has 243k, tq locker, edge juice w/attitude,fass 95gph,turbo timer,high idle box,home made air intake and intake horn.mbrp 4" turbo back.Truck ran ran great before this problem.

Have you tried disabling the edge, I was also wondering if you see anything abnormal on the gauges? high temps or fp low maybe?

How do u disable it? And does it hurt anything doing that? No abnormal readings that I'm aware of, about 17psi fuel, normal temp and egts

Remove the power from the edge unit it should be trunked off a fused circuit, then the stock PCM and ECM will do the stock tune as always.

Ok thanks I'll try when I get outa work

I'm glad to see someone else is pitching in on this. Did you try a reset on your apps yet?

I Tryed reseting the Tps again and worked for 2 min then back again to problems, I'm not positive but if I stay in the throttle it acts better? But still will do the dead pedal when normal driving

Hmm. Resetting fixed mine when I had the dead pedal. That's how I knew it was time to replace it. Is it still throwing codes? All the codes you posted before were apps related.

I may have to bow out of this one, as I'm still learning my truck too. I can assure you that you are in good hands with Jet though.

I don't know nothing lol you are doing good Girl! all you can do is offer advice and yours is logical. Its hard to troubleshoot over the phone or in a forum but you just give your angle and by process of elimination hopefully its fixed. :rocking:

Awe thanks Jet. I am calling bs on your knowledge level though. You were great in helping me try and figure out my trans problem.:tu:

Craig- Have you had any of the hunt for gears problems leading up to your dead pedal? I also just noticed that you said tps. Do you have a manual in the truck? Sorry if you already stated and I overlooked. To be honest with you, if you can afford to order the apps sensor, I suggest you go ahead and do so to keep as insurance. This part is notorious for being a p.i.t.a. It wouldn't hurt to have on hand for the just in case.

Mines auto, I orderd the apps from dodge yesterday, I get dealer cost from my boss so not bad and they said it's an updated sensor so here's to hopeing!! And I have had some wierd gear searching going on�� . Thanks for all the help it's nice to have other options and experiences

Went to get my special order sensor from dodge today...and it was def not the right part damit another weekend without my truck!!

If you have had the weird gear searching going on, I would lean towards it being the APPS. I sent you a private message in regards to apps suppliers. I feel ya on being without the truck. I have only gotten to use mine less than a dozen times in the last year and a half. Its been killer. Good luck and update when you can.

Thanks for all the help!!

You are welcome!
