Mackpro Posted July 28, 2022 Share Posted July 28, 2022 On MP8’s. Looking on the left hand side of engine. Look to the right of the engine ECM . There are two sensors screwed into the block at an angle, one above the other. The top one is the crankcase pressure sensor. Bottom one is oil pressure sensor. The part number has been updated several times due to high failure rate of early ones. This same part numbered sensor is used in several locations on the engine as fuel pressure sensor , piston cooling oil pressure sensor and AHI fuel pressure sensor. MP7 locations are different than the MP8. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70190-oil-pressure-sending-unit/#findComment-504662 Share on other sites More sharing options...
Dirtymilkman Posted July 29, 2022 Share Posted July 29, 2022 There should be a pigtail on the harness end that supposedly prevents oil wicking up the harness from sensor failure. I replace the pigtail too. Quote Link to comment https://www.bigmacktrucks.com/topic/70190-oil-pressure-sending-unit/#findComment-504732 Share on other sites More sharing options...
