Map is weak Coolant is not. I THINK oil pressure is also, but I have not checked it, but it reads high pressure also.

ok thanks. So another piece of the puzzle, the map plug shows 1.29v with no sensor connected coming from the ecm, rather than 5v......... I am also getting a p0236 error with no quad plugged in which makes sense if the ecm is putting out 1.29v vs the 5ish it should be.......

I just ran out and tested the grounds on map and coolant and they are good to go so I am ruling out busted ground. Mike, Does the ground on the passenger battery that grounds the pcm and ecm also ground the sensors that are connected to the ECM? IE if I unplug the passenger side ground connection should all my sensors not ground on their pins?

Yep, strange that this all happened at the same time. I need to go out there and test the Ground s165 I really wish I knew which sensor did what between the cam and crank. strangely the crank sensor is on it's own ground..... Also very strange that the truck was running fine but the tach was dead. The tach would come and go, but I suppose that makes sense if the pcm / ecm was telling the cluster hey the cpk is bad.

that is beautiful...... Room next door for me to move in?

Water to air intercooler...... that's cool.

I do....well I did.... it is hacked apart and the USB --> Bluetooth ripped out and bypassed directly to Serial so I can read Canbus data for my turbo controller So I do...but it is too much work to get it working with my phone again. I need to buy another one, but I have been lazy. Yep p0237 with the quad plugged in and no code with the quad unplugged. Only codes present were 336 and 237 so I am guessing that the vp44 is til good ( at least I hope) I now also have a non-starting truck sitting at work.....ugh HOWEVER my oil pressure is now reading 99PSI so I am really thinking I have a ground issue or something similar, I am gonna dive into the wiring diagrams and see if I can't race some wires over lunch. I just can't imagine 3 sensors going bad at once.

Yea I was a little taken back by the 1688 code haha. I am gonna reload the quad again, drive home, borrow a scanner and see what comes up. ( I reloaded the quad last night using a virtual machine with a virtual USB passthrough driver so who knows what effect that had on the flasher program hahahahaha. I am guess, well hoping that the reload will fix the strange readings. I accidentally unplugged the ADR box with the truck on so some of those codes are due to that.

Well on the way home last night I decided to get on the skinny pedal some on the onramp. Truck pulled great egt's nice no issues, let out of it somewhat fast and barked the turbo and BAM lost my RPM gauge, CEL pops on.....ugh, Truck drives fine all the way home so I thought eh who knows. Last night I decided I also wanted to load a new tune onto my ADR to try and clean up some of the low end smoke if I am on it. I have extra fuel thanks to the DFI injectors so I don't really need the aggressive tuning down low. So I load the factory tune back onto the ADR. Jump in the truck this morning and my Quad says my Boost is at 11 PSI just sitting there, and my oil pressure gauge is reading 10-12psi no change with RPM...... RPM gauge on the dash comes and goes, but the quad screen shows RPM fine so I know that the ECM is seeing RPM fine. WTS is working good and I have .01 ac noise so I am good there. Codes are p1756 p743 p336 p336 or 337 cant remember p1688 and p0235 So seeing as all of this happened right as soon as I let off I am all but positive that the issue is a bad ground or something, maybe I melted a wire. Anyways I will dig deeper into it later today, but I figured I would let you guys know the fun I had.

We got 18" of snow 7 days ago...and I can see dry bare ground....sucks. Well sadly nothing new came in the mail today so nothing to report.

Yea when you are in that situation you just gotta take it.

Whats the CND $ at right now? 60-70% USD?

ouch

Well I am %100 sure that's what happened but for the better good we are calling it an accident

Well I have some bad news...... Jen tried to wash the 28 year old blinds and they are no more haha. So she is working on new blinds too. I am gonna miss those 1980's goodness blinds

intake tube from my Wifes truck that had an oiled filter on it.

Show him this.... gotta love that free flowing intake

I would rather have it single digits than anything above 90.

You are right, PCM controls the charging. Thanks for catching that.

I would first test your alternator for AC noise. A LOT of ECM issues are due to failed Diodes in the Alternator

Yea, I know. but there hot weather between the comfortable months.

I am gonna miss winter.

you get to do all the boring work...... Not looking forward to that.

Alright, We got word that we should be seeing the harness's for the Mopar1973Man High Idle Switches by the end of next week.

Alright kill switch came in today, but that's it.... Battery box and wiring is done. So you plug the battery box into the camper, and plug the other end of the harness into the 7 pin plug, turn the big red switch to "on" when you are loaded up and ready to go camping so that you top off the charge on the drive to the site. When you get to the site just turn the kill switch off and you effectively disconnect the camper && camper battery from the truck. no risk of running the truck batteries dead. Well come along!
