2nd Generation Dodge 24 Valve Powertrain

I’ve joined the group of dead ecm’s. I had the delayed WTS light for a few years. Other than that no other problems until last week. I went to start the truck and no WTS light, no lift pump, and no start. I sent it off to Auto Computer Specialist in Florida after seeing they were recommended on here. They received it yesterday about this time. I haven’t heard anything from them yet, I figured it might be a couple days before I hear anything. Can someone who has used them give me an idea of the turnaround time? I will post back on here how my experience goes with them.

Ok my 2000 nv5600 just died it has a broke gear and what looks to be broken syncro pieces laying in the bottom, the fluid was full and i was not towing i was in traffic at a light and it locked up, now i have a choice to make do i put $3000 in for i 5600 or convert to a nv4500 if i convert i know ill need the trans and bellhousing,flywheel, clutch and drive shafts. My question is will the 4500 bolt in place and will my tc bolt up and where can i find cheep drive shafts they are hard to find here

First break down, and first post here. I think its awesome that there are resources like this site to help others. This is my first diesel and I love it. I have put about 40k on it the past 2 or 2.5 years. Majority Highway miles. it has about 254,000 on it now and had 213,000 a few years ago when i bought it. I really like wrenching and fixing things, but with this being my first diesel, and something new to me i am a little hesitant and nervous to do some stuff, but only because i dont really know exactly what im looking at. Well today on my way home I was passing a semi and then bam, no power(throttle) what so ever. Turned off radio, tried to restart, nothing. Put haza…

I've got a new one. I have the following codes; 0112 Intake Air Temp Sensor voltage low, 0230 Lift pump circuit out of range (This doesn't surprise me much as I took off the electric pump and have been running the mechanical pump for a few months now. Maybe I should have did something with the wires instead of just unplugging them), 0237 Manifold Air Pressure sensor voltage low, and 1475 Aux 5 volt supply voltage hi. The dead pedal affects the top speed. My acceleration sucks and it tops out about 55/60.Now I have heard 1475 is one of the codes that shows up when the ECM takes a dump but it accompanies codes from all the sensors and the alternator starts putting out crazy…

HELLO EVERYONE, I HAVE A 2001 2500 4x4 SLT WITH A CUMMINS ANYWAY IT STARTED ABOUT 6mnts AGO WHEN THE FACTORY WIRE TIES HOLDING THE HARNESS BROKE. EVERY NOW AND THEN I WOULD GET A CHECK LIGHT FOR APPS OUT OF RANGE.I WOULD UNPLUG AND RESET IT BE OK FOR MAYBE A MONTH AND THEN THE NEXT TIME YOU WOULD START IT BE ON AGAIN. WELL NOW I GET A DEAD PEDAL ONCE IN AWHILE AND MY FUEL MILAGE SEEMS TO HAVE DROPPED. I ORDERERD A TIMPO APPS YESTERDAY I BELIEVE THAT SHOULD HELP IF NOT IT WONT HURT. DO YOU ALL THINK I'M ON THE RIGHT TRACK.THANKS

My truck (2000 2500 automatic w/103K) has a bad case of dead pedal.I went by Autozone and had them read the codes and the only one was overboost.I cleared it and none have returned.It also has a fairly new fass ddrp lift pump on it.Once in a while it wil take off like normal for 2 or 3 presses of the accelerator; then just return to the same old dead pedal.Can the APPS be checked with a digital volt meter?Any other ideas? probably VP44?thanks in advance.joek

About 2 weeks ago I had the apps replace with a timbo sensor (previuosly I had made adjustment to my original apps 4 months ago) because it was showing trouble when shifting betwen 2nd a nd 3rd gear and also prensented the dead pedal symtom while i was driving on the freeway 65mph and when i release the pedal power was back. Any way after i replace the timbo sensor i drive over 1200 w/out any issue at all. suddenly today i was driving on the freeway 65 mhp and felt the loss of power, but my tachometer remain still @1900 rpms, so step on the gas and got power back release it to maintain 65 mph and symptom appear again then went gone. Also I notice trany again is having ha…

On my way home from work the other day, on the freeway, my truck started to hiccup a bit. It got worse by the minute and within about 5 miles, the truck would only respond to the throttle when it wanted to, dead pedal. I thought right away my VP had gone bad. I hobbled home and checked the codes. My OBD2 scan tool showed 0122, The truck showed P ECU, P 1693, P 0500, P 1475, P 0122. I ordered a Blue Chip VP-44 and installed it this morning, no change. I went down to the Dodge dealership and picked up a Bellcrank and installed that, no change. When I push down on the throttle, there is no response. If I push and hold the throttle, at any position, even slight, it eventually…

Just wanted to share a dead pedal experience. One March 19, 2018, during a return trip from Crescent City pulling my travel trailer, I exerienced the dead pedal syndrome about fifteen times in the last 35 miles to home. Each event lasted about 20 seconds (sometimes longer). It was a slow 35 miles, but the truck made it home. At this time the truck had logged a total of 289,000 miles with 202,000 miles on the VP44. The check engine light came on and stayed on and code P0121 ( Accelerator Position Sensor Signal Voltage Too Low) was set. I was hoping that I could replace the APPS and the problem would be resolved. I went on-line to Blue Ch…

Fuel pressure is up around 20 at idle, drops to 15-16 when I get on it. No codes though. I did have a 0216 code from when my lift pump went out over a year ago but it cleared and has never came back. No codes at all? It stopped doing it for awhile but started doing it again. After I shut it off and start it again (sometimes more than once) its fine. Any suggestions on where to start without codes. Ive searched the forum , alot of dead pedal issues but they have codes.

My first post here, hello! I am having a dead pedal issue with my 98.5 24V 4x4 2500 5spd, which I bought new, has 183K miles now.Earlier in the year, the dead pedal was accompanied by the check engine light and codes, and I replaced the MAP sensor to fix the issue. I believe the cause may have been related to a fuel leak from the fuel heater grommet, and saturated the MAP sensor plug after a hauling trip to NM when I was pushing more fuel out. I removed the fuel heater and plugged the grommet hole.About mid year, I "fixed" the 5th gear nut issue, I disconnected my batteries before wire welding the nut to the shaft (laughs or applauses insert here). I have never had to res…

So I need some help. About 5 months ago I got the dead pedal. Got the codes saying it's bad so I replaced it from timbo and worked for a few hours then it happen again. The next day I replaced all battery terminals and fixed it for a few weeks. Once again dead pedal again. Found out one battery was bad and the other going bad. Replaced both and fixed the issue until now. I'm having dead pedal again and have no clue what's going on. I can't find anything and just need help. It is a 2001 ram 2500 24v with 75hp injectors rebuilt trans all new terminals and batteries.

Hi I'm new to the site but have learned so much and hoping you guys can help me out. I've been getting a dead pedal at 53-55lbs of boost, things I've done aside from power mods are auto to nv5600 and 2001 fuel filter with twist off cap. Power mods are on my profile. I've replaced apps, map sensor, made sure the quadzilla is good, have good fuel preassure, and great power till that specific boost. Any ideas would help. Thanks.

When i start my truck it has no throttle response (dead Pedal), I let it idle for about 5 to 10 minutes, turn off truck and restart throttle response returns and it runs great. I have replaced the Throttle position sensor and still has same issue. I have tried to check for AC noise but don't have the right tester, i have removed the 140 alternator fuse and it still has same issue, next stepp is to remove alternator and have it tested. Any other option would be greatly appreciated. Thank you

I have an 01 cummins, the other day while driving 75 with the cruise on, my truck started to hesitate and jerk a bit. The truck then had a dead pedal and engine light came on and threw a bunch of codes. I had it towed back to a shop. The next day I went to see if I could figure any of it out. I changed the APP sensor and calibrated it to between .50v and .60v like the instructions told me. I still get dead pedal while driving and my coolant gauge goes all the way in the red when the dead pedal happens. I switched out the ECM with a spare one out of another truck in the shop and its doing the same exact thing like my old one. Im told I have an electrical problem but…

Well I think my apps finally started acting up on my 2000 CTD. We’re on our way to McCall Idaho for vacation, were a little south of Council and slowing for construction I accelerate just a little, about 25-30 MPH, to get through the construction and the throttle does nothing then picks up and acts normal. Of course the check engine light comes on and stays on. It acts up one more time while slow acceleration going through McCall. Get to the RV park and after the second start up the light goes out so it probably won’t have a code. Will have to get a code reader at NAPA tomorrow. I’ve got a new APPS with me, just hope the RV Park lets me work on it. I’m sure that’s…

Having a dead pedal issue on my 2002 24v auto. codes are p0122 p0236 p1475. problem is very intermittent. New apps sensor after confirming all apps power grounds and signals were good. when i have a pedal map and apps reading are were they should be, when problem is occurring map voltage is maxed out and apps signal is all over the place. Initially thought short between apps wiring and map wiring, could not find such short and did not notice change during wiggle test of harness nor could i measure continuity between apps and map circuit. Starting to think bad ecm, the problem did start after bleeding my low pressure fuel system getting diesel all over driver side of eng…

Ok guys I've posted on Cummins forum but not much help. My vp went bad about 10 months ago I replaced it truck ran good. 2 moths later dead pedal started I bumped my fuel pressure up on airdog165 local shop had it way low. Truck ran good for 6 months. Dead pedal came back also had a low voltage to apps code changed apps with a timbo and adjusted it per instructions. No more codexpensive but I still have the dead pedal. Spoke with local shop and changed ecm. Still have the dead pedal!! For giggles I changed my fairly new filters and added 2 grounds along with changing terminals made it 2 and 1/2 months and dead pedal is back. Spoke with a few people including calling bl…

A few days ago, I experienced a random dead pedal issue on my lunch break at work. I went to go grab some lunch and everything was fine. Got back to the job site and killed the engine to eat. When I went to start it back up, I put it into drive and started to take off through the parking lot. At the moment I started to put my foot on the pedal a little, I realized I had no response. I mashed it and still nothing. Long story short, called a roll off tow truck, when he got there, it worked again. 2 days later (replaced TPS that day), dead pedal again. Reading forums and stuff to find sequences, all fuses are good, CEL went away when I pulled a fuse to test voltage on. Put i…

Help! I am getting a dead pedal every 20 minutes or so during driving on a 2002 Cummins only when the outside temps are above 70 degrees and the truck is really hot. When the outside temp is below 70 degrees the truck runs fine. I've reset the APPS just like I've read on this forum and I've cleaned the sensors. I am not getting in check engine lights at all. Thanks in advance for any help!
