1999 ISB 275 Oil Pressure Sensor Part

Hi All,

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.

Thank you!

Scott

Before buying a new oil pressure sensor, they are easy to test. Remove the sensor from the engine block. Using a 12v test light, connect the base to negative of a battery and the test light to the positive post on the sensor. Using an air hose or a can of compressed air, blow in the opening in the base. If the light goes out, you know it works and the problem is somewhere else in the wiring system. If the sensor is bad, take it to an auto parts store and get a replacement.

It is still working fine!
80PSI when cold
50-60PSI warm both on gauge and ScanGaugeD
Before installing I hooked it to wiring and connected air line
with regulator, dash gauge and regulator gauge matched perfect!

Are you working on scott534 (the OP) engine? I'm a bit confused.

I believe Damion was the one who purchased and used the part I found on Amazon. Thank you for the test instructions, that will help in a big way!
