Output Shaft Speed Sensor

Motorcraft DY1250 Genuine OEM Output Shaft Speed Sensor

Restore crisp, predictable transmission shift points and clear your dashboard check engine warnings with the genuine factory-original Motorcraft DY1250 Output Shaft Speed Sensor. The Output Shaft Speed (OSS) sensor monitors the rotational speed of the transmission’s output shaft and relays this critical data to the powertrain control module (PCM) to calculate gear adjustments and electronic line pressure. Over time, internal magnetic components weaken, and electronic pins corrode from exposure to extreme transmission fluid temperatures, resulting in hard shifts, unexpected downshifts, or a speedometer that stops working. Choosing this genuine OEM part guarantees full system restoration without the compatibility risks of universal components.

Genuine Ford Engineering for Flawless Drivetrain Synchronization

Built under the exact manufacturing guidelines dictated by Ford Motor Company, the Motorcraft DY1250 features premium electromagnetic coils protected by a robust, chemical-resistant polymer housing. This heavy-duty casing completely seals out pressurized transmission fluid, moisture, and road contaminants that typically short-circuit low-quality alternative sensors. Its precisely calibrated internal hardware ensures zero signal lag, allowing your vehicle’s computer to execute smooth, efficient gear changes instantly.

Key Features & Performance Benefits

• Genuine Factory OEM Part: Identical in fitment, form, and electrical resistance to the sensor installed on the assembly line when your vehicle was built.
• Eliminates Transmission Glitches: Resolves common diagnostic trouble codes (DTCs) related to transmission speed anomalies and limp-mode triggers.
• Direct Plug-and-Play Installation: O-ring sealed body and matching factory harness dimensions provide a simple, leak-free bolt-on installation.
• Consistent Data Delivery: Maintained signal integrity across a wide thermal spectrum preserves fuel economy and prevents rough torque converter locking.

Installation and Fitment Note

Before installing your new sensor, check the electrical wire harness connector for any signs of internal fluid weeping or brittle locking tabs, as a cracked connector can degrade electrical conductivity. Always apply a tiny smear of clean transmission fluid to the integrated rubber O-ring to prevent tearing during insertion. Please cross-reference your vehicle’s specific transmission code or VIN to ensure complete part compatibility.
