felicello122 Posted October 7, 2016 Share Posted October 7, 2016 I just purchased a 2010 titan tractor with 605 mp10, bought it from a kw dealer, truck was defined to 585 by previous owner, I bought it and took it to a local Mack dealer and some issues fixed paid by kw, had them bump up back to 605 and address some electrical issues. Got truck back and can't complete one week without a shutdown from the oil pressure sensor, took it back to Mack they replaced the oil pressure sensor checked the gauge oil pressure is good, hit the road same problem, truck shuts off and starts again will run few more miles and repeat it again. Mack can't find anything, I'm thinking about another garage, and possibly a harness swap, anyone with a titan having issues like this? Need to start making money to much downtime, truck has just under 400,000 miles. They also replaced some relief valve associated with the oil pressure.

Timmyb Posted October 11, 2016 Share Posted October 11, 2016 Can u bridge the wires to fool the computer into thinking it's ok? I did that on my coolant sensor. It would be a temporary fix. Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted October 11, 2016 Share Posted October 11, 2016 Are you sure there isn't something floating around in the oil gallery behind the pressure sensor and getting pushed up on the gallery and reducing flow? Maybe try an old style mechanical pressure gauge a few zip ties up in to the cab and see if you are loosing oil pressure when it happens.
