2nd Generation Dodge 24 Valve Powertrain

This is a discussion forum of the 1998.5 to 2002 2nd Generation Dodge Ram Trucks with 5.9L Cummins 24 Valve Turbo Diesel power train and drive line system. This includes all sub-system including wiring, fuel, oil, exhaust, air, transmission, computers and sensors.

  1. Hi I recently purchased a 2001 3500 - 4x4 - 6 speed manual - quad cab. It has just under 98k miles on it. It has an edge tuner, banks 4" exhaust, Banks exhaust brake, pyrometer gauge and turbo boost gauge. It had a quite a bit of differed maintenance and a few needed repairs so I'm getting that all caught up first. The check engine light came on 2 weeks ago and I pulled P1693 + P1690. The truck was running but seemed a but sluggish at the time. I changed the fuel filter, which was really grungy. I cleared the codes and measured the fuel pressure which came in at just under 15 psi. I also changed the air filter. I drove…

    Hello guys, I've been working on a 2000 5 speed truck for a friend that's got me scratching my head. Truck has just over 300k on it and was cutting out randomly and would shudder and he said it was worse when it was cold. Truck had no error codes, new fuel filter, both batteries and alternator are new. I drove it my Snap on scanner on it watching live data on a graph. I could see the APPS signal going whack when truck would act up. Had another VP truck at the house so "borrowed" good working TPS quick to verify that was the issue. Truck ran great with that factory style TPS with no issues. So I ordered the "commercial grade" APPS sensor from DieselAutoPower.com since they…

    My alternator output is less when warm out than when cold. Now it’s putting out 14.3 on average. When it’s hot it’s more like 13.7. Is this an indication of trouble ahead?

    I have an 01 Ram 2500 5.9 that the clutch was just replaced after sitting a few months, picked it up and drove 30 plus miles no problem, next day drove 20 miles and it just quit, no sputtering or anything, just shut down. Had it towed and have checked and replaced fuel filter, bleed system, getting fuel to injectors 134. Codes, (key method)P1693 and P0122. Have electronic apps, have reset, but that should not keep from starting. Cranks strong, just will not start. maybe, fuse/relay or wire loose? any suggestions. Thanks

    Is there a 200 degree thermostat that I can put in my 2001 24 Valve? Can you post the link to one, or a part number? The region I'm in sees temps averaging between -15 to 0 degrees Fahrenheit. Opinions are always welcome!

    I have a fairly good idea of how the lockup switch works. I am curious though, if you install a switch but don't have the switch on, will the converter lock/unlock like normal? Do you have to control it 100% of the time if you install the switch? I'm not really sure I need or want to do it, these are just questions I keep asking myself every time I see a post related to it.

    Today making a drive to drop off some deer meat to be packaged, my trucks alternator voltage jumped to 18v for a couple of minutes, then went back to normal. First thing I am going to check is my grounds. If they check out to be clean and good should I put in a external voltage regulator like on the 12 valves?

    Ok gang... I'm going to share a few tidbit of information for advance OBDII tinkering. If you happen to have a OBDLink or ELM327 tool you should be able to tag along here. I will have to give a bit of thanks to @Me78569 for getting me started with the Bluetooth terminal on Android. Once I had that I could directly communicate with the OBDLink and pass commands to it. So starting out I passed the command... ATSP0 This basically tells the tool to communication with the detected protocol of the vehicle ours happens to be ISO 9141-2 protocol. After that I passed the command... 0100 Which happens to be PID Mode 01 with the PID 00 which tells th…

    Ok I love the sound of my truck, it’s straight piped to a large tip and has an open air box with great turbo sound. But I have to say it, it’s too loud. So simple question, can I make it quieter without sacrificing flow? Looking maybe at muffler or dual mufflers or maybe some sort of attenuator. I daily drive and use this for normal stuff like going through a drive through or stopping to talk for a second with friends or other parents at my kids school. But I also use it like a work truck, towing and hauling campers, equipment, firewood, etc. Can anyone help with this dilemma?

  17. Too good to be true, the truck was running good, not overheating. Last night, I saw a puddle, maybe an oil leak. I checked and after running, it is leaking a mixture of oil and antifreeze by the front case, above the oil pan. It's lost a quart, it runs fine, but the killer dowel pin is a possibility. 2001 shouldn't have a killer dowel pin? Has anyone heard of this, and is the likely source the water pump? The engine runs, so the engine seems okay. Thoughts? And thanks for the help.

    Hey guys, This is my first post over here. Id like to thank Mopar1973Man for having this forum and for all the information he contributes. The trouble code walkthoughs are an amazing resource. I am trying to resolve P1689 and P0215 DTCs. Truck: 01 QCLB CTD Auto 4wd. Pertinent upgrades: FASS system 95gph, smartry and original quadzilla adrenaline. There are lots of other upgrades, but none that should relate to my question. Backround: Truck was sitting for the better part of two years. When I stopped driving it, it was running well. When I came back to start it again, I had a no crank issue that ended up being a bad ignition switch.…
