Oil Pressure went to 0 at idle
 

Hey guys

Started the 2000 5.9 this morning and all was fine. The oil pressure showed fine so as it warmed up I went back in the house. I came out and the oil pressure showed 0 and the check gauges light was on. I shut it down and checked the oil. It was ok. There was no abnormal noise. I pulled the filled cap and all looks wet up top. Sound like a sending unit? Im reading these are pretty common and looks like Cummins is the place to buy it, Stealership is like 250! ANy help would be appreciated! Thanks!

Id try the sending unit first then go from there.

Do you or anyone know if Cummins part #4921511 will work?

This is a lot cheaper:

'98.5-'02 Dodge Turbo Diesel Oil Pressure Sensor-Geno's Garage


Also, check to see if you have a Cummins dealer in the area. I know I can get genuine Cummins parts cheaper from a truck (semi) dealer than the stealership.

Thanks guys. I went off and left my serial number at home. Ill have to get that off the truck or out of the book and give them a call. They gave me a part # but wanted the serial number to confirm. Sounds like this is a pretty common occurance.

Yep senors are a wear part, so you will have to replace them from time to time.:c:

Thanks , Yeah just sucks when its the one for oil pressure, about gave me a heart attack! :scare2: This is my first diesel which I have had it awhile but still learning. Im checking with my local Cummins guy to see what he can do for one.

mine is stuck on reading 40 psi it never moves

To ease your mind and be sure its the sending unit, go to orielly's and get a cheap manual oil pressure gauge. I picked one up for $18. There is a port on top of the oil filter you can hook it up to.

Mine went out and oil pr. dropped to zero. I don't have the number now but the price was far cheaper at the cummins dealer the dodge people wanted to sell me a different part with some adapter for twice the price. but I think I paid about $65 dollars. the info is on my dead computer.
