Oil Pressure Sensor on Cummins 340hp ISB

[EdCarp]

Can anyone tell me where the sensor is located? I have a 2015 Newmar Ventana LE 3850. Engine access is through a hatch on the bedroom floor. Before embarking on hatch removal - I'd like to have an idea of where to look.
Thanks in advance.

There is a lot of good information on the Cummins Quickserve site which is free. You have to create an account and then register your engine SN. You can then do a parts search.

At some point I found a document that has a picture of all the sensor locations on my engine.

Lots of other good information there once you figure out how to navigate through all of it. Parts, maintenance, troubleshooting.


My oil pressure sensor is above the starter, but I have an 8.3 ISC!

Hon that engine it is located on the drivers side of the engine right above the oil pan. It can be reached by going under the coach. Gonna be tight fit. I will have 2 wires attached to it. Had mine quit working and Cummins covered it at about 5 years.

On my ISC (which may well be totally different from your engine!) the OPS is on the intake side of the engine, mid way back, mid way up. Mine has two wires, and nut terminals.
