So there’s no oil pressure sender on a Cummins?
Odd that the gauges in the off road pages show the temp ring, but not instrument panel…
The isn't an oil pressure sensor or oil temperature sensor. There is an oil psi switch, so as long as you have 6 psi of pressure (10 psi is the minimum at idle per Cummins) our gauge will read "normal".
Do you know if anyone has tested the oil temp, and oil pressure to see how close the calculated display is to the real temp and pressure?
I ran real oil psi and oil temp gauges in my 05. The oil pressure is rarely correct, the real oil pressure swings much more rapidly and sits lower at idle-1500 rpms.
Oil temp is decent, close enough that I thought I was a real reading when my dad bought his 2017 and I still had my 2005. It's a little funky when cold, like it will drop from 190 to 160 on an off ramp, which isn't realistic. It also doesn't get quite as warm on a long hard pull, but it's generally closer than oil pressure.
But that's all just for fun, neither one, especially oil temp, will ever let you know if there is an issue.
