P0298 - Engine Oil OVERTEMPERATURE Condition

WARNING: This page is about a different car, the 2008 Ford Pickup, 2008 Ford F550 Super Duty, 2008 Ford F450 Super Duty, and 2008 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
P0298 - ENGINE OIL OVERTEMPERATURE 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. On engines which are equipped with an engine oil temperature (EOT) sensor, the PCM reads the oil temperature to determine if it is excessive. When an EOT sensor is not present, the PCM uses an oil algorithm to infer actual temperature.
Possible Causes: 
  • Very high engine RPM for an extended period of time
  • Overheating condition
  • Damaged EOT sensor or circuit
  • Thermostat
  • Cooling system
Diagnostic Aids:  The engine is operating in high RPM range due to incorrect gear selection. This may cause a lack/loss of power or surge concern.
