• Other Names:

  Sensor Assembly Speed, DY1230

• Description:

  This is the genuine Ford vehicle speed sensor, the magnetic sensor that reads output shaft or driveline rotation and reports vehicle speed to the speedometer and powertrain control so the transmission knows when to shift and the speedometer reads correctly. Cataloged by Ford as a speed sensor assembly, it produces a signal proportional to speed from its magnetized sensing tip. This part serves 99-04 F-250, F-350, F-450 and F-550 Super Duty applications. Owners look for this sensor when the speedometer is erratic or dead, cruise control drops out, the transmission shifts harshly or at the wrong points, or a speed-sensor trouble code is set. Because the sensor sits in the driveline exposed to heat, vibration, and gear oil and relies on a magnetic pickup, its element or wiring can fail over time, which produces a lost or erratic speed signal, a common cause of speedometer and shift complaints on these trucks. A failed speed sensor affects the speedometer, cruise, and transmission behavior. Installing the correct genuine sensor restores an accurate speed signal and proper shift timing. As an original Ford component it matches the mounting, sensing gap, and connector exactly so it reads accurately and plugs into the factory harness. Confirm the transmission and connector against your vehicle before ordering to ensure correct fit, and inspect the sensor mounting bore and O-ring during installation for a clean, leak-free fit.
