The oil thermostat is located in the oil filter housing and controls the engine oil temperature by controlling if the oil is sent through the oil cooler or not. The Engine Control Module (ECM) monitors that the thermostat is working as expected by comparing the Engine Oil Pressure (EOP) Sensor value to a calculated oil temperature.
