Replacement REPF321601 Accelerator Pedal Position Sensor 8-Cyl 7.3L Powerstroke

The Replacement REPF321601 is a direct-fit Accelerator Pedal Position (APP) Sensor engineered for Ford F-Series Super Duty pickups equipped with the 7.3L Power Stroke diesel V8 engine. This sensor monitors the position of the accelerator pedal and transmits the corresponding electronic signal to the engine control module (ECM), enabling precise throttle response and smooth acceleration. A failed APP sensor can result in poor acceleration, erratic throttle response, reduced engine power, or an illuminated check engine light — making timely replacement essential for safe and reliable operation.

This aftermarket replacement is designed to match the fit and function of the original equipment sensor, restoring proper throttle control without the need for special tools or programming. The plug-and-play design makes installation straightforward for DIY mechanics and professionals alike.

Key Features:

• Direct OEM replacement — matches original fit and function
• Plug-and-play installation — no special tools or programming required
• Restores proper throttle response and drivability
• Built to meet or exceed original equipment specifications
• Application-specific design for 8-cylinder 7.3L Power Stroke engines
