1991 Trooper Oil Pressure Sensor?
 

I have a 1991 Trooper with a 4 cylinder engine. I have a Haynes manual and nowhere in it does it show where the oil pressure sensor is located. Anyone have any clue as to where it is? :confused:

hey how it goin,i have a chilton's manual my book says located on the side of the engine/do you know what it looks like,it looks like a small cup with two this wires on it , hope this helps...trooper76

On the 4 cylinder, the oil pressure sending unit (for the oil pressure gauge) is located on the oil filter adapter. On the passenger side of motor, look down at the oil filter. In proximity to the filter, you should see a large metallic, brass colored object, roundish to bell shaped. It should have a single wire connector which slides over the contact of the sending unit.
