Ford Motorcraft Engine Oil Pressure (EOP) Sensor Ford (1999-10) 7.3L & 6.0L Power Stroke

The Ford Motorcraft F81Z-9278-AA Engine Oil Pressure (EOP) Sensor is a genuine OE replacement for select 1999–2010 Ford 7.3L and 6.0L Power Stroke diesel applications. The sensor monitors engine oil pressure and supplies the signal used by the vehicle’s oil-pressure gauge and warning system.

An oil-pressure sender that has failed, developed an internal electrical fault, leaked at the sensor body, or become intermittent can cause inaccurate gauge readings or oil-pressure warning concerns. Replacing a confirmed faulty sensor can restore dependable pressure indication, but the sensor should not be used as a substitute for properly diagnosing an actual engine-oil-pressure problem.

Motorcraft part number F81Z-9278-AA, also referenced as SW-5267, is built for OE-style fit, connector compatibility, and calibration on supported Power Stroke trucks. It is a dependable service replacement for stock trucks, work vehicles, tow rigs, and restoration-focused diesel builds that need a factory-quality oil-pressure sender.

Before replacing the sensor, inspect the electrical connector and wiring for oil contamination, corrosion, looseness, or damage. If the truck shows a low-oil-pressure warning, unusual engine noise, or other lubrication-related symptoms, verify actual mechanical oil pressure and oil condition before operating the engine or assuming the sensor is the only issue.
