P0298 Infiniti Engine Oil Over Temperature Condition
Possible causes
– Low or dirty motor oil condition
– Faulty Oil Pressure Switch
– Faulty Engine Oil Temperature (EOT) sensor
– Engine overheating condition
– Very high engine RPM for an extended period of time
– Faulty Oil Pressure Switch
– Faulty Engine Oil Temperature (EOT) sensor
– Engine overheating condition
– Very high engine RPM for an extended period of time
Tech description
On engines which are equipped with an oil temperature sensor, the Engine Control Module (ECM) reads oil temperature to determine if it is excessive. When an oil temperature sensor is not present, the ECM uses an oil algorithm to infer actual temperature. Engine shutdown strategy function is the same on vehicles with and without oil temperature sensors.
What about the obd code?
P0298 Infiniti is set when the vehicle has been running below 1,000 rpm and less than 20 mg/stroke MFDES with EOT sensor signal reading above 110 C (230 F). The time to set the fault is dependent on EOT and Intake Air Temperature (IAT) temperatures, and can vary between approx. 15 to 45 minutes
Symptoms
– Engine Light ON (or Service Engine Soon Warning Light)
P0298 Infiniti Description
Indicates the Engine Oil Temperature Protection (EOT) strategy in the Engine Control Module (ECM) has been activated. This temporarily prohibits high engine speed operation by disabling injectors, reducing the risk of engine damage from high engine oil temperature.
