Similarly, a degraded pressure relief valve might fail to open and close correctly, often leading to lower-than-normal idle pressure. Never ignore a warning light, as it is a direct communication from the vehicle's safety systems.
Another possibility is insufficient oil volume or a leak in the system, which reduces the overall hydraulic pressure the pump can create. A common cause is a worn oil pump, which struggles to generate sufficient pressure at low RPMs.
