I am running into this problem where my oil pressure sensor is working for a bit then it goes up at 100 PSI and doesn’t go down from there. I changed the oil pressure sensor and the oil temp pressure sensor. and still no help. Any help will kindly be appreciated

MX13 has an electronically-controlled, variable oil pressure system. When it fails, you get maximum oil pressure, all the time. Mine is doing the same thing and I don’t yet know what component fails and causes it. I have an appointment, 2/28.

I never made it into the dealer, 2/28. This morning, the oil pressure dropped to normal and the wrench light went off. Afterward, the oil pressure bounced up a couple times, then, stayed normal. I can’t explain it other than to say another PACCAR doing PACCAR things.
