Ok gang I need you guys to double check me on this here...Truck Specs: 2002 Dodge Cummins - 128K miles - 2500 - Stock(No its not my truck!)Error Code list:P0113 - Intake Air Temp Sensor Voltage High Intake air (charge) temperature sensor input above the maximum acceptable voltage.P0118 - ECT Sensor Voltage Too High Engine coolant temperature sensor input above the maximum acceptable voltageP0238 - Map Sensor Voltage Too High MAP sensor voltage input above the maximum acceptable voltage.P0343 - Camshaft Position Sensor Circuit High InputP0563 - Charging System Voltage Too High Supply voltage sensed at ECM too high.P0577 - Cruise Control Related MalfunctionP1286 - Accelerator Position Sensor (APPS) Supply Voltage Too High High voltage detected at APPSP1475 - Aux 5 Volt Supply Voltage High Sensor supply voltage for ECM sensors is too high.I've not had a chance to verify the battery volts while running. But at idle the engine is randomly reving up to nearing 2K on the tach. Gauges are going wild all rising up randomly. Durin the short time I was there the coolant temp gauge pegged out (cold engine).My thought on it is the PCM voltage regulator is fried out... But I want to make sure and double check myself against the group here...

There is a lot you can do... most just sand it down and paint it over... Time to get creative! :D

sorry the 4.89 is the upper limit... From what I'm finding... But your only showing 4.77 Volts... So your with in specs yet from what I'm reading form the FSM...

4.89 Volts is the limt... But your only hitting 4.77 Volts... :confused:

Glad your fixed up... Glad it was a easy fix for ya... :thumbsup

Hmmm... P1763 - Governor Pressure Sensor Volts Too HI Voltage greater than 4.89 volts (4-speed auto. trans. only).So now you need to tap that wire and measure the voltage on the fly. Then you might have to adjust you resistor to reduce the voltage to bring it back in line. But make sure the voltage isn't because its shorted out to 12V by chance throwing the code...

About time you show up...Geez! LOL welcome to my lil' forum...

I found out that there was a report of 2002 that had KDP failure that did damage... :wow The guy was nice enough to post the receipt from the dealer showing the repairs on a 2002 Dodge...

I'm going to point out to everyone there is NO WAY to have just a P1693 code present during error code dumping. Yes the P1693 is a companion code and has no really meaning but... "This code indicates there is more code present in the other computer" So if the P1693 is in the P PCU that means there is more codes present in the P ECU. So if there is a P1693 in the P ECU that means there is more codes present in the P PCU. Then even in rare cases seeing the P1693 code in both computers pointing out that both computers have codes. But there is NO WAY for the P1693 to be the only codes present during error code dump. It's totally impossible! The reason I'm posting this is because it seem like everyone is cancelling out at the first P DONE thinking its done. WRONG! There is TWO computers in the truck. P PCU = Powertrain Controller Unit (Passenger side firewall) P ECU = Engine Controller Unit (Driver side of engine block) You should always see both P PCU and P ECU displayed and 2 P DONE's in the display. If you want to see a video of this and how to properly do it please reffer to my web site and watch the video I produced so you can give us acurrate information on your problems your having with your truck. Here is the page with the video of how its done... http://mopar.mopar1973man.com/cummins/2ndgen24v/obd2-error-codes/obd2-error-codes.htm Now the other thing is alot of people are getting error code from OBD II sites or from manuals with the scanners. I'll point out that any code over P1000 is a manufacture specific code that only applies to the that make and model of vehicle so please refer to a proper Factory service manual and get the proper codes. I've got some books listed on my site provided by PDFTown.com http://pdftown.com/Dodge-Ram-2001-Service-Manual.html As for 2nd Gen 24V error codes I copied the error code listing straight out of the Dodge FSM for our truck and made a short PDF file for viewing... http://mopar.mopar1973man.com/cummins/2ndgen24v/obd2-error-codes/error-codes.pdf This will help us diagnose your problem quickly and properly.

Page fixed... http://mopar.mopar1973man.com/tips/cumm ... _codes.htm

The page happens to be missing... Let me fix that problem...

Hmmm... If you a SO Engine... Nope... Dumb idea though... :confused: As for the key I've got a solution for that... Another member told me... "Super Glue!" LOL

Hmmm... JL... Do you have any new error codes at all?You might try a cam sensor for the tach jump but I don';t think that going to cure the strange idle jump issue... Is there someone you could swap VP44 with? :confused:

Hmmm... Not sure about MAX pressure but you seem to have enough... That's for sure... :thumbsup

Good point... LOL

There was a crazy of that back when I first started with the Cummins Crowd. But then it seen to just fade away... :confused: You rarely here of pre-luber now...

Here head over and download a book on the 2001 Dodge and there is a full guide on how to deal with the chain... http://pdftown.com/Dodge-Ram-2001-Service-Manual.html

Not sure... :confused:

That book happens to be in my pile... :smart

You got a rip in the VP44 diaphram. The pressure is to great at start up so the solution is just like you said you got to disconnect the lift pump form the system during starts now. So for a permanent fix I would wire in a relay to the starter lead so it turns the pump OFF during cranking but as soon as the key is relase the pump comes ON. The other solution is replace the VP44... The whole cause of this problem was from low fuel pressure and a diaphram inside the VP44 ripped during this low pressure moment.

1 MPG could be you lead filled boot causing that... BHAF should ZERO effect on MPG as long as its clean and not pulling the filter minder down. Chips should have ZERO to do with it as long as the throttle doesn't touch the carpet.Try something..."keep you boost below 5 PSI and Pyrometer under 600*F and I bet 20+ MPG will happen"Remember... Pyrometer will rise if you dumping large amounts of fuel to the engine. Boost can only becreated from large amounts of fuel. So if you keep both very low then you not burn much fuel arn't you??? LOL

Getting below 100:1 is to hot of a idea... remember all oils are natural cetane reducers... So if you get it too low it will trouble some to start. If you looking at HFRR number play with the calculator a bit for 2 cycle oil... http://mopar.mopar1973man.com/tips/cumm ... r-calc.htm

Well it jumped here in Idaho... :mad From $2.129 to $2.429 now... I'm heading for $3.00 really soon again... :nono

Well when you get it back it should work like a dream... :thumbsup

I don't see any reason why not... I would give it the 128:1 dose and take a rod and stir it up good in the tank. Then at least prime up the low pressure side with fresh fuel and fire it up...
