High oil system pressure shows up when system pressure goes beyond the upper limit parameters in the system. High system pressure may be caused by the following conditions: Pressure relief valve sticking closed. This valve is located in the engine oil pump or close to it. The valve limits the maximum oil pressure allowed in the system and opens when the maximum allowed pressure is reached, usually between 40 and 60 psi, depending on the model. Otherwise, the pressure will rise.
