Hello All,
I am fairly new to this site but I have received a lot of help from other members. I have a 2001 Ram 2500 with the 24v Cummings. I have had the dead pedal issue twice with this truck. The first round, I ended up going through and removing, cleaning and greasing all of the ground wires I could find under the hood. One of them was bad and this fixed the issue. This last go-round with the dead pedal, the problem was very intermittent. I was getting numerous codes including 1690, 1693, 0122. I adjusted the voltage at the APPS. It was low when I started. That took care of the 0122 code. I also spoke with a tech at out local dodge dealer. He gave me a factory wiring fix that by-passed the ECM. You add a wire at the PCM, and wire it directly to the APPS and you also add another ground directly to the battery. This repair was for the erratic shift issue. I can post the diagram if need be. While having the dead pedal issue the transmission was shifting all of the time, In and out of overdrive. Unfortunately this did not fix the dead pedal issue or the shifting issue. The truck would idle fine most of the time, but every so often it would "hiccup" if you will. During one of the "hiccups" I noticed a little puff of smoke coming from the solenoid on the side of the fuel filter. As it turns out, the culprit of all of my issues was the solenoid for the fuel heater in the fuel filter. There were some bare wires and it was fried. I replaced the solenoid as well as the actual fuel heater in the filter and the truck ran fine. Cost was around $240. I know the headaches of the dead pedal issue and I hope this helps.
