    Truck is a 90 T600 with a 8TC PEEC engine that has been converted to mechanical.

    Oil temperature gauge does not work. Need to know where the oil temperature sensor should be then hopefully I can verify the wiring and repair what needs to be fixed.

    Oil pressure fluctuates from 30 to 60. No real rhyme or reason for fluctuation.. it does not respond to rpm. Thinking a bad sending unit or bad connection. What is the location of the pressure sensor?

    Thanks in advance

    Generally the sending unit for the gauge is somewhere on the oil pan. The sending unit to the ecm, may be near the oil temp thermostat by the oil cooler, or oil filter head assembly(depending on the engine).

    Thanks. I found a sensor in the oil pan that isn't hooked up and no wires near it. I'll figure it out when the snow melts lol
