MackGirl352 Posted February 2, 2018 Share Posted February 2, 2018 (edited) 2000 Mack vision cx613 e7 400 gauge reading low oil pressure, no codes, no lights, no shut downs runs fine. Checked oil it's fine...but the gauge reads low oil pressure. Reads low enough where the truck would go into automatic shutdown. Could it be a sensor or a bad gauge?

MackGirl352 Posted February 2, 2018 Author Share Posted February 2, 2018 Where is the oil sensor on the 2000 model? Going to change oil this weekend to see if that helps.

Dirtymilkman Posted February 3, 2018 Share Posted February 3, 2018 Your best thing to do would be to hook up a mechanical gauge to check oil pressure. Any cheap pressure gauge will work. I believe at idle you need very little oil pressure. How well is the Jake brake working? That's a telltale too if you have low pressure.

Timmyb Posted February 3, 2018 Share Posted February 3, 2018 If it’s an electronic gauge it’s most likely the oil pressure sender. Same thing happened to my gauge not so long ago.

880joe Posted February 3, 2018 Share Posted February 3, 2018 The sensor will be on top of the filter housing Quote Link to comment https://www.bigmacktrucks.com/topic/52386-gauge-reading-low-oil-pressure/#findComment-391047 Share on other sites More sharing options...
