I have a 1998 Larame SLE with a 12 valve cummins and a standard
trans................. A week after I drove the truck off the lot when it
was brand new, the oil pressure alarm started coming on. I took it to the
Dodge boys and a new sensor was installed on warranty. Now 100 thousand
kilometers later (aprox 60 thousand miles), I have the oil pressure alarm
come on as pull into the driveway, usually after taking a long trip on the
highway....
Is there a way to test the sensor? I really don't beleive that the truck
is actually losing oil pressure. The engine runs great.

Does the cummins have sensor problems ?.... I have been googling this
topic and find I'm not the only one... Thanks...Jim

I assume you've checked the oil level on the dipstick, and made sure it's
full?

Easiest way is to hook up a mechanical pressure gauge. There should be some
1/8"NPT fittings on the oil filter housing.
