CM870 Crank Position Sensor Part Number - pwhittle - 12-20-2024

My CM870 was showing a code, and Insite showed 284 Engine Speed/position Sensor (Crankshaft) Supply Voltage Circuit Voltage ??? Normal, or shorted to low source.

First of all, I am impressed the Cummins would run without that input. I would expect a no start condition on most engines.

Secondly, I am disappointed in QuickServe. It would not take my password and when I try to reset my password, it showed a server error. I also +reated another account with a different email and never received the welcome email.

Would someone be able to confirm the part number for me? ESN is 79079781.

I suspect it is 4921599, but want to make sure.

Thanks!

Quickserve never worked for me not once, always says error

Use (parts.cummins.com)instead

I looked at parts.cummins.com, entered my ESN, and could not locate the crankshaft position sensor.

Perhaps my search skills are weak.

That site doesn't work very well. Maybe it's only certain engines?? I've never had much luck looking up parts there. I've put in part numbers for parts I know for a fact are for the engine and it will say the part isn't for this ESN.
