02 Volvo daycab with pre-EGR Cummins ISX.. oil pressure data erratic or incorrect ??

Hello

I get PID 100 FM2 - oil pressure sensor circuit data erratic, intermittent or incorrect

My truck is 2002 Volvo daycab with non egr Cummins ISX engine ( data plate on engine says its from 2010 )

Where is oil pressure sensor on this engine?? - behind fuel filter under IFSM there is one sensor with 4 wires going in to it - is it the one?

And does it have some places on the cab where cables can get fray or cut since error was intermittent and now is constant?

Please any info will be greatly appreciated

 

nobody ??

 

turned out to be just a oil pressure and temperautre sensor - two in one - $240 at my dealer, found for $165 on the internet
