johnrworley Posted November 28, 2014 Share Posted November 28, 2014 Started my truck ran for 15 min. Left home approx. 3/4 mile low oil pressure alarms went off truck shut down I let it sit 10 min restarted oil pressure 10 - 12 lbs shut it off. 5 min repeated same result. I'm wondering if the pressure relief valve that's electronic is a possibility any thoughts?

johnrworley Posted November 28, 2014 Author Share Posted November 28, 2014 10-12 was the idle. I found the problem to be the oil pressure sensor. Thanks for the response.

Mackpro Posted December 1, 2014 Share Posted December 1, 2014 We have replaced 100's of oil pressure sensors sometimes 2 or more times per truck. Hopefully this newest part# will be better.
