Tech Notes for P0298 Mazda

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.

When is the Code Detected?

P0298 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
