2002 Ford Expedition Vehicle Speed Sensor Parts Questions & Experts Answers

• Q: How to service and repair the Vehicle Speed Sensor for the Turbine Shaft and Output Shaft on 2002 Ford Expedition?

  A: The first step in servicing or repairing Turbine Shaft Speed (TSS) sensor and Output Shaft Speed (OSS) sensor consists of removing drive shaft components together with rear transmission mount nuts. Be mindful about keeping the transmission back from reaching an unsafe height that could strike the underbody because this might harm the TSS and OSS sensors. Start by taking out the rear transmission mount along with lifting the transmission off its support at the rear crossmember point before detaching the rear transmission mount through bolt removal. Begin sensor replacement by lowering the transmission. Start by removing the bolt from TSS followed by both sensors. The procedure for the OSS sensor involves first removing its bolt then its sensor component. The first step to installation requires sensor O-ring lubrication before installing the OSS sensor which must then be secured using the bolt. The installation procedure for the TSS sensor requires repeating the sensor lubrication methods. Check that the transmission back remains at a proper height to avoid sensor damage. Reinstall the rear transmission mount by first elevating the transmission then securing bolts before dropping it onto the rear crossmember support and ending with a final installation of rear transmission mount nuts to reinstall the drive shaft.
