2nd Generation Dodge 24 Valve Powertrain

My son has a 2002 Dodge 2500 Diesel has codes P0522 and P0336. The oil pressure switch, which is a single wire switch, has been replaced with a Cummins part and the PO336 code is troubling because there is no crank shaft sensor on a 2002. When you start the truck the instrument cluster shows no oil pressure and the tach is erratic for 8 seconds then drops off and the truck runs at a normal RPM but is in limp mode. ANY help would be appreciated.

I have a code just set for the first time yesterday sure yesterday it was PO238 map sensor voltage high, I cleared this yesterday to see what would happen today Turned ignition on today and PO237 map sensor voltage low set, no PO238 Done the diagnostics for the 237 code and everything checks out except map voltage is 0.5v ignition on not running or running, it does increase to around 1v to 1.6v if stalled in gear I got 5.2v on orange which tells me the 5v supply is good, no other sensor codes set no short to earth on the other 2 wires or each other I haven't disconnected the ecm plugs and checked continuity of these two Fitted a quad a…

My trans stuck in 2nd after rebuild changed gov an tranducer. And has no codes was thinkin maybe kickdown cable Should i adjust slack screw should that lever be touching valva body pin

Ok guys got my vacuum pump resealed, no more oil being pushed out the CCV, and got my vacuum lines replace so my heater works on all positions. Fixed the banjo bolt leak on the back of the head, and T fitting leak on the return line. But I still have a bad problem until the truck is fully warm it has no power still, and if the outside temp is below 40 it loses power bad. And still have a hard starting issue has to crank for around 20 seconds and then until it sets for about 3 hours itll stat back instantly. New batteries, cranks fast, new fuel filters, fass DRRP lift pump. 15psi fuel pressure idle, 9 WOT. Any ideas would help I'm thinking my VP44 is shitting the bed it's …

Ok. So long story short, I tried to swap the old 150 injectors into my truck after I went through and set all the pop off pressures with shims(diesel class project). They're pretty much junk, considering they do nothing but just smoke out everything behind the truck. I ended up going back to the stocker set I got from a good guy from here (name escapes me atm, but thank you again amigo). Had hell getting the truck started again, which I think was because I backed the truck into my spot at home, and it was leaning back slightly (the road has a crown). I got a friend and he helped me get her going again, but as it was idling, it started pouring fuel out of the bottow. We tr…

Came home from work today to find my new Dynamic valve body sitting on the table. Forgot to pick up a new filter so I'll have to wait until tomorrow to put it in.

Damn was getting ready to do the WT ground mod and noticed the upper mount tab is broken on my Alternator. It's a bosch. Are the bosch and denso alternators interchangeable? I've been shopping around for a replacement but seems to be some confusion about the correct alternator, depending on the eighth digit of the vin. ( in my case it's "C") Advance auto has the actual bosch alternator (based on the alternator part#) but the listing says it's for trucks with a vin: 7 https://shop.advanceautoparts.com/p/bosch-premium-100-remanufactured-alternator-al6400x/20851271-P?navigationPath=L1*14920|L2*14999|L3*15587 Rock auto has an alternator …

Hi Guys.. new here, but have been reading as a guest for a while. I’m always amazed at how knowledgable a lot of you guys are and all the helpful information available. Here’s my situation, and I’ll try to remember a much detail as I can and in the proper sequence. Last year my truck was sitting for about 7-8 months without use. I was helping one of my parents out of town and wasn’t able to do much else. So when I got home, my truck batteries were totally dead. These were new batteries, maybe 4 months old prior to leaving. I couldn’t get them to take a charge. Took them in, load tested, replaced. Then the truck’s EVS II system wouldn’t disarm and I think the d…

I haven't been on a forum in many years but you kinda need to go back to them when you have a real question that needs to be answered. I have an 01 Dodge Ram 2500, auto, Quadzilla, 75 injectors, 62/68/12 and a Airdog I run the Quad on the stock tune on the fuel saving tune and bump it up one when towing I just installed my 3 piece manifold so I have my Quadzilla and Edge CTS probes installed and have really noticed my EGTs. They seem to be around 800 in flat ground and up to 1100 on small hills. I was told maybe it has a boost leak which I have checked. My truck can hit 25 lbs quick but kinda seems to max out but my wastegate should open at 35. May…

As my first post, thanks for all you do for the rest of us...I appreciate you all more than you know. I’m going through the step by step for this code and have run into a snag at step 5. Looking for confirmation with someone else before I start cutting wires. By these results I’m guessing a problem with both my white and black wires between the FPCM and the ECM and I should replace both. (Ironically both these wires have a weird little twist coming out of the FPCM) FYI. Just finished the W-T ground mod. Waiting on a circuit breaker to do the positive side. If anyone could confirm my suspicions, i would greatly appreciate it. 5. …

Howdy there everyone, hope everyone is well and healthy! So during this “pandemic” slow days at work has given me more free time to mess with the 24v so I have some 7x.12 nozzles that I’ve had laying around but I know they’re way too much for my he351 because as of right now I still get tons of turbo shutter, looking at new turbo options, on Power Driven Diesel my preferred place to get parts, they have upgraded he351’s 62,64,67mm anyone have any luck with these? Or I’m looking at an sxe 362 or 364.5 if I was to go this route would I go a .70 or .80 t3 housing? I’m looking to be around 550-600hp on a single yes I know compounds the way to go on these 24v’s but man droppin…

Looking to identify where this plug is supposed to go the wire colors are Yellow/Blue, Yellow/Green, Black/White. It's located next to the ECM on the right side of the motor as you face the truck. just above the engine mounted fuel pump. I unplugged it from a pigtail system which is in the attached photos. There are zero markings as to what this box is/does, the small tag on the wire loom is not legible the only thing I can pick out on it is "4-02tdw". Any help would be appreciated, I reconnected the cannot plug to the left of the one in question as well that's depicted in the first photo. This was also connected to the system in box in question. …

Sorry guys, I posted the other day with a P1689 Code, which is now gone and hasn’t come back. Starts and idles great. Sounds perfect, just won’t rev over 2000rpm. I assume just waiting to pop back up. While watching live stream I noticed these voltage readings. Any ideas as to why, or what’s up? Grid heaters are unhooked by the way. IMG_3223.MOV

So Ive had the Gould pump reseal kit for awhile and decided since I got all this downtime I would go and rebuild it this morning. Everything was goin great until I started to drive the seal retainer out of the housing. I cannot get the damn thing to budge. Using a big dead blow and the provided driver tool, even used a 2x4 and a 3lb sledge and that sucker wont budge. Anyone had this issue or any tips/tricks?

Hey folks need advice on how effective adding a aux trans cooler will be to keeping my trans temps in check, I bought my 2001 with 300k from my uncle in law. He was the original owner and always serviced it at my father in law's shop. I only using for hunting, camping and occasional trailer hauling trips. I'm a park ranger in Nevada and love backcountry hunting, climbing, mountain biking etc... My favorite spot involves a 45+ minute climb in 4LO to get up a series of switchbacks from 5500' to 8000'. The transmission, and eventually the motor gets hot. Trans 225+ motor 210. Juice will read the temp sensor I installed in the transmission on passenger…

I had my truck parked for 7 days under the covered shelter. Haven't started or drove it in a week. Been Raining for a week and off work. I just noticed a little wet spot stain on the concrete inside the driver front wheel this morning. Turns out the power steering pump leaked a little out the cap like it was over filled but it hasnt been. Started the truck and backed straight back and then noticed no power steering and no power brakes. Stopped got out , checked the reservoir and had oil in it and as the truck idled for a few minutes I could see the oil inside the pump start flowing and pump working. Got back in the truck and the power…

I just received my high idle switch kit. I'm trying to figure out how to install. I have an ejwa currently installed. How do I need to connect the high idle harness to the jwa? Thanks for any help! Jason 1999 24v

Over the last week I've noticed some strange behaviors from my truck and want you all's opinion on whether I'm being paranoid, I just need some maintenance, I'm about to have a serious truck breakdown to deal with, or something else altogether. Background: I'm in Minnesota, and my fuel tank is full of local "Premium" diesel. Temps are ranging from the 20s to even a few days in the 60s. Fuel from the same station I've used a lot in the past, newer station, sells lots of diesel. Other guys I work with fuel here, too, no problems. I'm running my Quad on Level 2 for MPG, as I have for a few thousand miles. Fuel pressure is unchanged. Can hardly tell about M…

Evening first time poster! I've been lurking this forum for a bit now with the anticipation of purchasing a new to me 2001 with 160,xxx, new to the 5.9 but have owned two 6.7's in the past. Today while looking under the rig it appears to be coolant behind the harmonic balancer. I went for the water pump and thermostat housing first but no joy on any coolant leakage. Besides the radiator hoses where else should I look for a possible leak OR what could fluid being in that spot indicate? Also of note after a short drive I crawled under and saw some drops on the steering linkage and some drips on the concrete. The seller recently worked on the oil pan gasket and n…

Hi guys, my 2002 5.9 24 valve has some issues and I want to verify I am doing the correct things before proceeding. It runs poorly and surges, the temp gauge is going near full almost immediately, and the check engine light is on. There are several high voltage codes including (P0563 charging system, P1475 Aux 5 volt output, P1286 APPS supply voltage, P0113 Intake air temp sensor, P0118 ECT voltage, P0238 MAP sensor) all stating voltage too high. Now I also have the P0606 ECM/PCM Processor code. I did an alternator A/C noise test and it failed (otherwise the charging system seems normal). I am able to scan codes but can not communicate to get any data whatsoever. My plan …
