My co-worker's 2001 Jeep Grand Cherokee Limited with the 4.7L V-8 has a problem with the oil pressure reading on the guage. Often at idle, the guage would read 0 psi, but as soon as he came off idle, the pressure guage jumped up. Now, the guage is reading 0 psi almost constantly. The oil looks fine and the engine is not making abnormal sounds, so I suspect a faulty sending unit/sensor.

My OTC Genisys scan tool claims the sending unit is on the upper portion of the engine near the distributor. However, his engine has CoP ignition, no distributor, and after a quick look, I didn't see anything on the top half the engine that I thought was the sending unit.

Would anyone be so kind as to tell me where the sending unit can be found on the 2001 4.7L?

most of your oil sending unit is not far from your oil filter..good luck....

That was my thought, so I was surprised when the scan tool mentioned near the distributor.

I only glanced under the hood in the work parking lot, haven't climbed under it yet.
