Code P0298 1998 Ford F150 Description

The P0298 engine code for a 1998 Ford F150 indicates an Engine Oil Over Temperature Condition. This means that the engine oil in the vehicle is reaching higher temperatures than normal, which can have detrimental effects on the engine's performance and longevity. When engine oil overheats, it can lose its lubricating properties, causing increased friction and wear on engine components. This can lead to engine damage, decreased fuel efficiency, and potential engine failure if not addressed promptly.

Tech Notes for P0298 1998 Ford F150

Indicates the Engine Oil Temperature Protection strategy in the PCM has been activated. This will temporarily prohibit high engine speed operation by disabling injectors, therefore 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.

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
