Question about Jeep Grand Cherokee
If there is no tapping from the engine, likely the problem is a bad pressure sending switch. If there is a noise it may be from lifters or bearings and you will need to put a mechanical gauge on it to read actual oil pressure (your gauge is electro-mechanical and not as accurate) Low pressure can be from obstructed oil pump screen or bearing problems. Replacing pump is usually a waste of time unless you correct the real problem.

the sensor is on the side of the engine block. there's two thing that monitors oil. a pressure switch turns you oil light on and you oil pressure sensor the operates your gauge, start with your sensor. that is near you oil filter that is where it gets it pressure reading from

Same part...make sure you get one for gauge, not idiot light though. If the engine has any knocking or ticking when pressure drops do not drive it and have a mechanical gauge installed to check actual pressure. Parts often have different names for same item...your driveshaft is actually called a propeller shaft!!!
