I have an 04 3500 5.9ho, and I keep getting an intermittent p0336 code, it'll go away some times and come back. I've replaced the sensor 3 times now, and it still has a problem, my only thoughts are it's the harness, tuner or (hopefully not)ecm, any insight? The symptoms are it just misses every now and then, starts fine and runs alright for the most part just a little rough now and then, almost like a lope.

Really need some truck details to be able to help. Auto/manual, mileage, and any mods to start with.

Fill in a Sig, click on account details on the upper right side of the screen, then click on Account Settings, then scroll down the left side of the screen and click on Signature.

Be sure you have 2 good batteries 12.6V and the terminals are clean and secure.
Return to stock tuning, if running a tuner
List any other symptoms - black smoke, white smoke, hard starts, etc.

Loose connection or chaffed wire.

Manual nv5600, 269k miles, has a tst powermax tuner (installed by previous owner) and a airdog lp, when it's throwing the code it can start a little rough but not terrible, no smoke or anything outside of usual connection at harness should be fine I don't know if the harness is chaffed elsewhere, I haven't returned to stock tuning when the code pops up, could that help?

Also batteries are both pretty new and connections are pretty good. What is a signature, and why do I fill that out? I'm a cummins forum noob.

It puts your truck info at the bottom of your posts, which knowing makes it easier to help with questions. See mine below

Ahh ok, well I made a reply with the info you requested, I've done some research on this tuner and it bridges between the CKP and cmp sensors, as well as the injectors harnesses, seems mega sketch to me, I may be upgrading to an edge soon because of that

To avoid throwing parts at issue should go thru diagnostics ;)

That's pretty in depth lol, honestly to skip that I'd just replace the harness, it's pretty rough and I've found multiple wires that were expossed so it'd probably be worth my time and money just to replace the whole thing, the problem is I just can't fine an engine harness anywhere online, if you guys know where I could get one I'd greatly appreciate it for for sure, but honestly I've been doing research on the tuner the previous owner put on the truck, and it's the type that plugs in to the injector harness, ckp harness, and cmp harness, it's a common type but it's probably 15 years old and it changes tunes on its own occasionally and with the intermittent nature of the code it may just be causing a communication error, but either way if that don't fix it I need to find a harness, I appreciate your help

Most everything electrical on these trucks is in-depth. Amazes me as to how so many different systems can seem to, cross-contaminate, and cause symptoms in other things.

I would try disconnect/remove tuner to rule out. Get simpler modern tuner that uses just reliable datalink, ie Smarty/ HP tuner.

As far as harness, not sure where you are going to find a OEM harness(es) , get lucky find NOS, or good one in junk yard, Otherwise Painless Wiring is possible option they make some for swaps.

Yeah there's says it's not suitable for oem replacement though, so not sure how that would work, it's way to difficult to get something that goes out so often on any vehicle

So I recently had a no start situation with it, map code, i ripped the tuner off and haven’t had an issue since

The TST Powermax was never that good nor popular for common rails when it came out in 2004.
It is an extremely intrusive and complicated interceptor type module that connected to a ton of engine sensors.

IMO, no one should be using a TST Powermax these days, nor any type of interceptor module.

so what tuner would you recommend for a replacement? I was looking at the edge cts2 possibly.

I would need way more info on your truck, what you use your truck for and what your goals are before I can make a recommendation.

This tuner's website has some good info and options for the 2004.5 model year.

I am not associated with him nor do I have any of his products.

its bone stock with an airdog lift pump, just for some fun, not a race truck or anything, just something simple plug and play, not interested in efi live or any custom tunes
