Code P0298 2009 Ford Fusion Description

Indicates the engine oil temperature protection strategy in the Powertrain Control Module (PCM) has been activated. This temporarily prohibits high engine speed operation by disabling injectors, to reduce the risk of engine damage from high engine oil temperature. On engines equipped with an oil temperature sensor, the PCM reads oil temperature to determine if it is excessive. When an oil temperature sensor is not present, the PCM uses an oil algorithm to determine actual temperature. Engine shutdown strategy function is the same on vehicles with and without oil temperature sensors.
