I have researched most threads on this issue, but can't seem to find a solid answer. I am 99% sure my oil pressure sensor is bad, as my gauge is reading "0" and the dipstick shows full with no drips/leaks.
I read there was a replacement sensor that Cummings was using that also required a new harness, but it was quite expensive.
Does anyone know or have you ever changed out your oil sensor using a replacement part? Do you know the part number?
On another thread, a member used this part, but I would like to confirm with someone who actually knows about it.
