The role of the Ford Focus Speed Sensor is measuring transmission output shaft rotation and sending vehicle speed information to the onboard computer. A Ford permanent magnet or reed-type device generates an electronic signal whenever the toothed shaft passes the sensing element, allowing accurate road speed calculation. Equipped with throttle, temperature and pressure sensors, the computer combines this information with gearbox data to control hydraulic pressure, determine shift points and engage the torque converter clutch. When the Speed Sensor signal is missing or erratic, the computer may delay upshifts or may produce unusually firm shifts. It may also prevent torque converter lockup. Within the Focus automatic transmission system, therefore, the Speed Sensor is the primary reference for smooth gear change and consistent drivability. Other sensors such as turbine shaft speed and transmission fluid temperature can assist the control strategy but the Speed Sensor uniquely reflects actual vehicle motion. The part is built to original Ford specifications and connects directly to the Ford powertrain control architecture found on Focus vehicles. This results in speed information and stable operation. All in all, the Speed Sensor ensures reliable transmission performance in Focus.

Ford Focus Speed Sensor Parts and Q&A

  • Q: How to service and repair the Speed Sensor on the Output Shaft on Ford Focus?
    A:
    Before servicing the Output Shaft Speed (OSS) Sensor start by raising the vehicle then support it while placing a drain pan below. Remove the OSS sensor by disconnecting the electrical connector followed by unbolted the sensor. The OSS bore must be checked for damaged O-ring seal before installing a new O-ring replacement if damaged. A thin layer of petroleum jelly should be used to treat the O-ring before you install the OSS sensor. Reconnect the electrical connector after the installation and then lower the vehicle down while also verify that the transmission fluid maintains the proper level by adding more automatic transmission fluid when necessary. Use the engine to go through all gear positions with the transaxle range selector lever as a final step to verify proper functionality.
