My gauge is acting up. I know of the problems with the oil pressure sending units in our trucks, which is why I have ordered a mechanical gauge. The problem is, I can't stand the red "CHECK GAGES" light staying on.
I hate to spend $70 just to turn off that light. Below is a list of imformation to assist in solving this problem.

1: '01, 2500, 24 valve
2: The wire color codes in the harness are as follows:
Orange
Grey w/black
Blue w/black
If anymore information is needed feel free to e-mail or PM me. Thanks

 

GO TO Cummins and get the preasure sender and let know one reflash you with the updated crap period .!

 

I don't believe the "flash" for "oil psi drops off" applies to 01 trucks. A sending unit is in order.

 

Firestorm, ORANGE- 5v supply
Black/Blue- 12v pos.
Gray/Black- Engine oil pressure sensor signal

Don't have the time right now to trace the circuit, I'll check it out later

if you put in the new sender it will shut your lite off
