I have a 2001 Monaco Dynasty with a 2000 Cummins ISL 370 and 2000 Allison 3000 transmission.

I am replacing some gauges with require that I replace the Engine Temp Sensor, Engine Oil Pressure Sensor, and the Allision 3000 Temp Sensor.

Has anyone replaced their gauges before, requiring different Sensors?

I have two thoughts I need help with:

1. Where the heck are these sensors located?
2. Do I need to worry about the ECM inputs with the different sensors?

Thanks in Advance,
Bill

ECM sensors are separate from the ones Monaco installed for the gauges.

On my 350 hp ISC the water temp gauge is located behind the alternator. The transmission temp sensor is mounted in an aluminum block on the output hose of the transmission going to the cooler. Can't remember where the oil pressure.
Here are the ones used on my rig.

Thanks for the info Jim J.
Glad to hear Monaco uses different sensors than the Cummins ECM sensors.
How will I know which one to replace, I don't want to remove the ECM sensors by mistake.

Interesting, your ENG Temp Sensor uses 2 wires, my new one only has one.

Thanks for taking the time to help me.

Do you have a Cummins Quickserve account. https://quickserve.cummins.com/info/index.html

I use this website for lots of different information on my engine.

You should be able to find the info on the sensors used for the ECM. I downloaded a file that describes the engine and the sensors.

I have a quick serve account and have been looking. I found several diagrams of the engines but I don’t think I found the right one.. Perhaps you could share with me the one that you found and I’ll then know what I’m looking for when I see it?

Here are a couple that may help

Thanks Jim.
Would these be the sensors for the ECM, vice the sensors for the Gauges?

Yes, I believe these are the sensors for the ECM.

Guess I don’t wanna replace them if they are for the ECM.

If you have a Cummins Quickserve account there is an electrical diagram showing what sensors provide information to the ECM
Here's a screen shot, blurry but kinda shows you the detail
