Sounds to me like your oil pressure "Sender", went south! If you have oil flowing through the by-pass, you definately have oil pressure.

just got in out of sunny california SNOW and put a pressure gauge on and it is about 70psi. Have a friend that works at parts at cummins and will give her a call now. thanks ED

It is on the drivers side below the bottom of the fuel filter canister, right around the back side of the ecm.

If I'm not mistaken, I think you'll find it on the driver side of the engine, just to the rear of the Injector pump about 5-6 inches. Someone correct me if I'm wrong.

one more question if you don't mind, how many terminal on the pressure switch. Just too bitter out side for a spoiled sunny california guy to go out in. thanks ED

3 wires on the oil sensor . We are having a heat wave tonight, 16 degrees right now, but they are calling for single digits starting Monday night.

See below from my thread with almost the same title as yours - from July of this year. bottom line get part number 4088390nx it'll give you the correct function you want, or you could always get a aftermarket gage and then figure out how to deal with the constant "check gages light" on the dash.





From my 7/08 thread/



JR2 - Thanks for the info. Before I saw your reply I picked up the Cummins part #4076930 "Switch, Pressure" and the part # 3164755 "Cable Electrical". After looking at it I thought this is a switch! And, after reading the installation instructions where it reads "A re-calibration of the ECM is required with this procedure, Bla, Bla". And in a Note below it states "If a re-calibration is not performed, a persistent Fault Code 141 will exist. "



I decided to check the part mentioned in the link you provided to see if it's still good. Bingo! Part 4088390nx checked to be good, I asked if it was superseded by another part and was told yes that's 4921511 - Bingo again. It's on it's way to me for $83. 46 + UPS +/- $10. 00.



Although the part I got (Switch & Cable) was $25. 49 + whatever the dealer charge to re-flash my ECM I feel better with a gage that's a "gage" than a gage that's an "Idiot" light. And, My ECM is fine, I've heard the horror stories others have had when taking their truck in for what should be a simple re-flash. "We don't need no stinking dingbats screwing around in the ECM".



Thanks,



The TDR - "I love this place!"
