3Gen sensors are failing and need to be replaced with high quality sensors. My experience with cam and crank sensors, buy Mopar and replace BOTH. The ECU looks at both cam and crank sensors to be sure it's sync.

They way I read your post, you did not replace your injector harness/gasket. When we do our injectors the old harness/gasket will be replaced along with new tubes and sticks.

If it were my truck I would replace the injector harness/gasket and then look for an independent shop you can trust.

Normally folks list any mods to their trucks in their signature so they get more specific advice.

Long time reader first time poster! I bought this truck new in 2005. No mods, all stock. This truck does not have the injector wiring integrated in the gasket. I did install new tubes with the injectors. I called a cummins dealer when this first happened. They said they could not diagnose because of dodge proprietary software. He said all they could do is drop in new injectors, and they couldn't even sell me those. That's why I'm leaning towards a dealer. I'm thinking they have the right diagnostic software to find the problem.
Thanks for the info on the sensors.

Thanks for correcting me. I know the 06 fairly well but not the other years. It shows!

I'm not sure how you traced the wiring to trouble shoot #4. Did you ohm it out to the pin at the ECU?

I was lucky to find a tech who left Dodge and started his own shop. He knows Gen 1,2 and 3s Cummins. Dealerships is a hit and miss if they know anything about a Gen3. I'd think more miss....

Get the real Cummins C&C sensors, much less than the repackaged Mopar dealer parts counter. And NO eVomit online garbage unless you know who you are dealing with.
Genos Garage is the best online but much of the electrical parts are B/O'd

Have you ohm tested #4 yet? May hyave cracked brass stud or damaged the wire/connector
You may have Bosch official Bosch plant rebuilds, they are not as reliable as NEW MANUFACTURE Bosch.
What numbers on the injectors? Body or top of solenoids?

Injector wiring failures can be anywhere from the injector to the inputs into the ECU. Have to test all, common for these to get crushed damaged and interior corroded. Can also be damaged/corroded connectors at the ECU.
Remember Mopar has the worse wiring quality in the industry, that pickup is 16+ years old.

These are lots of hours to troubleshoot and repair because of the low quality of much of the Mopar junke on them, wiring ad naseum
If you can't take the strain, take it to a private diesel pickup shop in your area that specializes in Cummins Dodge.
Your state forum guys will recommend the best one in your area.
DO NOT TAKE IT TO a Dodge dealer shop, unless you have too much cash in the bank

 

I have spent hours tracing all injection wiring for open/grounded/shorted conditions from the ecm to the connectors. No issues. I have ohm'd all new injectors at 0.6. I have not checked numbers on the new injectors to verify they are truly new, I would like to think that injectors direct would not false advertise.(see attached) My next step is to replace cam/crank sensor. I am curious why there has been a design change on the cam sensor. Anyway, these are cheep parts to throw at it. If this doesn't fix the problem, ecm is next I guess. Thanks again for everyone's help.

 

If sure wires are good ie proper resistance testing , then ECM driver is shorted

 

@RodJ

The last link in my sig at the bottom of my post will take you to the page where you can make a sig with all the truck's info, which in turn makes it easier for other members to help you.

 

With that cam code I would be looking very closely ie testing F855 circuit, runs thru out truck, but most common issue with it found by AC compressor .

 

Injector direct is using term like Brand NEW, does not equal Virgins, There Remans are no more than house molest harvest pieces in most cases.

 

Short of me calling to verify, I would like to think they are being truthful. (See attachment

 

Nothing in that marketing ad claims they are Virgin Injectors, that last 3 digit indicates they are unused Bosch (238) Did you find 238 located anywhere on the Injectors? Bosch Genuine Remans last 3 digit for 2004.5 (505)RX... When companies offer Brand new many times its the 505 Injector. Now comes the ugly part Many companies are selling reman Injector that are NOT Bosch rebuild. This past week I dealt with problem twice, The Buyers are members of this site and may chime, Both purchased Bosch Reman Genuine, after multi times of removal Both purchase Genuine New form Us, I allowed both customers to Come here and install the injectors from Us.. both issues (different between both) somehow instantly solved, in both cases 2/3 Nozzle were cake up the rest were good.

We sold both 505/238 - 503/255 2009 to 2012 Both Injectors had the same morality rate 1 injector per 2723-2800 Sold. We offer the 238/255 etc only at buyers discretion, Companies that offer alternatives are likely to use the alternative.

I'm curious to know. Of the information I provided, what part indicates the injectors are not new? (Un used). Attached is a photo of the injectors I received.

What was the internet company that was coming on this forum selling NEW Bosch injectors for HPCR 5.9 Cummins. Turned out they were low spec injectors for low power tractor motors.🤣

How do you know she's a virgin, son?
She told me she is, Dad.

 

I hate that @RodJ spent good money, hours of labor and his truck is down from a miss leasing ad. I hope can get a refund.

I've, about, learned if the price is too good to be true, it probably isnt. I still compare the legitimatement companies to Fleebay. Then order the quality parts...

These engine parts have attracted so many shysters. I buy from folks I know and or trust.

 

I used ID when I replaced my injectors 50,000 miles ago. Truck is still running strong. It does seem strange that you have different issues after the install.

 

They look legit to me, can check numbers by going thru this thread

Regarding jkidd/DAP & BOSCH.....

Ok, I have been in contact with 2 people from Bosch. A lot of you arent going to like this, but this isnt my opinion anymore, this is fact, as shown by the emails from BOSCH, and jkidds/DAP's own words and actions. I have attached 3 screen shots of 3 emails involving 2 different representatives...

Reason most Cummins dealer shops won't touch these Italian/Frenchy Kissing MoFart Cummins diesels is that they have been boy toyed to death. No money in it for them on a less than $20K rig and they have to invest in the MoFart test equipment since MoFart holds the patent and copyright on the ECU firmware. They work on real trucks.

What was the compression results all 6 holes just before injector installs?

Check how it runs after you get new Bosch/Cummins only crank and cam P. sensors in it.

Stock fuel dirt filtration n water separator 2005?
Guaranteed dirty/rusty fuel system from stock OEM fuel filter housing on.
Installed injectors and tubes NOW stuffed full of rust n dirt.
CP3 likely rusted ate out garbage.
Rail and HP fuel lines rusty garbage
RPRV and RP sensor likely rusted plugged toasty critters.

Oh, Neither Bosch NOR Cummins will warranty these 5.9 HPCR injectors with stock OEM POS Italiano/Frenchy MoFarts filtration water separation. S.O.O.L.

 

Update: Replaced cam sensor with no improvement. Bit the bullet and sent the ECM to GoEcm. At first they said there were some bad transistors, and were in the process of repairing. Called them today to check status and they said it was not repairable and they were sending it back. Any ideas?

Sorry to read that your ECU is bad.

We changed crank and cam positions sensors in pairs because the ECU looks for both to synch. The Crank sensor is the easy one to change, too.

Why fried ECM? to hopefully avoid damaging replacement, go back to your codes, first step for P0341 cam code is find fix any fuel injectors codes, P0204 in your case, I would triple check wiring harnesses.

 

I have checked all high side and low side drivers for each injector numerous times. No open, grounded, or shorts to each of the other wires. Both cam and crank wiring check ok. The only thing I have not checked is all other wires in that connector for shorts to any other wire in that connector. Wondering if a componet (high side driver) in the ecm simply failed?

 

If sure wiring is good then possibly ECM could of just fried, just not very common.
Usually other electrical issues ie bad power/wiring/connectors cause damage.
Did ECM shop have any info other then "some bad transistors"?

 

She rattled off some information but I didn't quite hear what she was talking about. I'm supposed to get the ecm back today. Maybe there will be some information in the package. If not, I may call and see if they can give me some info. I contacted ACS, he said send it in. He was confident he may be able to repair.

 

Update: Put in a matching new crank sensor, and sent the ECM to auto computer specialist. Installed and fired up. Same thing! Only difference is I cleared the codes, and the only one that returned was the P2149. ABS and Brake light is on now. I, AGAIN went through the entire trouble shooting procedure in the service manual ending at ECM. I did find test 10 perplexing. I showed continuity, which made sense to me. (See attached) I'm about ready to haul to a shop!

 

The test is to check for a short or partial short in injector harness, between the 3 low side driver circuits.
need to properly measure resistance, ie meter zeroed between test, no power to circuit.
What is ohm value?
If less then 100K ohms Replace the injector harness.

 

What makes me question test #10 is the fact it instructs that the harness be connected at the rocker box. That being the case, the small amount of voltage to check resistance flows down the low side wire, thru the injector, into the high side wire, thru the next injector, and up the other low side wire. (See schematic). I verified the same test on bank one, with same results.

 

IDK, very basic schematic, really not showing all what's really in the ECM as far as components that control and fire injectors.
If sure your resistance is above 100k then you passed.

 

Thats the problem I find with this test. Both banks show 0.5 ohms between each low side driver.

 

Did you replace the injector wiring harness/valve cover gasket when you installed new injectors?
