Engine/Transmission (1998.5 - 2002) Oil Pressure Gauge Problem

[Spurge]

I have a 2001 6 spd CTD and my oil pressure gauge isn't working. I can turn the key on and wait a little while and it'll go to 70psi without the engine running.

Is it the sending unit?

Has anyone else had this problem?

And How hard is it to fix?

Do Not Let The Dealer Reflash The PCM.



They will tell you you need an ECM/PCM update that will render your gauge worthless. Do a search on this and you will have lots of reading. I had the reflash done to my first 01.



Buy the sender from Cummins, ~$55 if I remember right. After they reflashed mine you could hang a sender in mid air and get 40 PSI on the dash.

Sounds like the sending unit. I had the same problem a few months ago. Do a search for the correct part number and get it from Cummins. One part number requires a PCM reflash one doesn't. Get the one that doesn't need a reflash.
