350 HP. 8.3 ISC Oil Pressure Sensor

[Damion]

Replaced my old 3408428 maxed out at 80 PSI. With the new 4921511 Threads and plug is all correct. Amazon $19

Yes it is! But I call Cummins they say 4921517 which is for ISX, plus need wire harness and $600-$800 in programing!
All I'm saying is the threads are correct and the plug is correct and it works just fine on my application. Your own choice!

Thanks for posting Damion. Does it show oil pressure on the Silverleaf? I was going to change mine, and was told by Cummins that they changed over to the new version. It’s more like an “idiot light”, showing 0 or 55 psi., and requires a reprogramming of the ecm.

If I had known about this sender, I would have tried this first. One positive note, the ecm was upgraded to the latest flash. The cost for the replacement and reprogramming was $800-.

It shows on dash gauge and on my ScanGauge D and $19 I'm in!

I believe my oil pressure sensor on my '99 ISB 275 is bad. Has this replacement part worked for you? What is your gauge reading after you replaced it? Thanks!

It is still working fine!
80PSI when cold
50-60PSI warm both on gauge and ScanGaugeD
Before installing I hooked it to wiring and connected air line
with regulator, dash gauge and regulator gauge matched perfect!

Has anyone else had success with this part number. My 2001 DSDP still has the original oil pressure center installed and working, but I don’t want to have to get an ECM reprogrammed and be down rated if it goes out. This sounds like the perfect solution

Where on the ISC did you find this sender? And is it for the dash gauge or is it the ECM oil pressure sender?

[Epp]

Passenger side of engine around the secondary fuel filter. I believe the sender sends the signal to the ECM and then ecm sends to the dash gauge.

I was also concerned about the potential to have to switch to an idiot light type sensor and the required reprogramming. Back ~3-4 years ago another Monaco member contacted me off line, he was having trouble with his rig derating. We worked through the obvious stuff and I finally suggested the oil pressure sensor. He was able to limp to a Cummins shop where they installed the idiot light sensor and reprogrammed his ECM for ~$450.



So last year, after hearing more of the same type issues I did a post and had some good feedback and one member said he did find an alternative for the obsolete original sensor, bought and installed and it worked. So i bought one to carry as a spare, but have not tried it. https://www.ebay.com/itm/384198815175




Also, Monaco actually installed their own sensor for the dash gauges, for oil pressure and engine/transmission temp. The Cummins sensor report to the ECM.

I read this thread and thought better have one so I bought it 3 years ago. When my oil pressure sender started to leak oil, I took the new sender out to install, well, it was wrong size, the thread diameter was obviously smaller. I couldn‘t use it. It still sits in my spare parts box.

I am not sure why it worked on OP‘s ISC 350 but not mine...

Where was the sender located you were trying to replace??

Hi Jim, it‘s on the side of the engine mid height on the same side of alternator and lift pump, if my memory serves me well. It‘s been a few years...
