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. Engine shutdown strategy function is the same on vehicles with and without EOT sensors.
Possible Causes: 
  • Very high engine RPM for an extended period of time
  • Overheating condition
  • Damaged EOT sensor or circuit (vehicles with an EOT sensor)
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 concern.
