DTC P0298: Engine Oil Over Temperature Condition

WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2005 Mercury Sable, 2005 Mercury Mountaineer, 2005 Mercury Monterey, 2005 Mercury Montego, and 2005 Mercury Mariner. However, it is still accessible from the selected car via links, so may be relevant.
P0298 - ENGINE OIL OVER TEMPERATURE CONDITION

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, reducing the risk of engine damage from high engine oil temperature. Note: On engines which are 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 infer actual temperature. Engine shutdown strategy function is the same on vehicles with and without oil temperature sensors.
Possible Causes: 
  • Very high engine RPM for an extended period of time
  • Overheating condition
  • Malfunctioning engine oil temperature (EOT) sensor or circuit (vehicles with an EOT sensor)
  • Base engine concerns
Diagnostic Aids:  The engine is operating in high RPM range due to improper gear selection. This may cause a lack/loss of power or surge customer concern.
