What causes high oil pressure in a Jeep?
Dirty or contaminated oil filter: The oil filter is there to filter out impurities from the engine oil. Over time, particles from dust, soot, rust, and gum get deposited in the filter and begin clogging the system. This leads to more resistance and higher oil pressure.
What should the oil pressure be on a Jeep Cherokee?
should be in the range of 15-50 psi under normal operating conditions. My 99′ with 153K when warm will idle at about 20PSI and when driving goes up to 40PSI. This is with synthetic oil. A good rule of thumb would be 10PSI per 1k RPM of the engine.
What to do about oil pressure in Jeep Grand Cherokee?

How does the oil sending unit work on a Jeep Cherokee?
The oil sending unit measures oil pressure and sends a signal to a sensor which engages the “Check Oil” or other gauge inside the Jeep. When oil loses it thickness and causes pressure disruptions the problem often results in a clogged galley, which runs to the oil sending unit.
What are the symptoms of high oil pressure?
