Q: What are the two speed sensors in the Ford Edge and where are they located?
A: Two speed sensors exist in a vehicle: the Turbine Shaft Speed (TSS) and Output Shaft Speed (OSS) sensors. The TSS is on the transaxle top, while the OSS is in the transaxle valve body. OSS sensor repair should be done by professionals. To remove it, lift the vehicle, remove the engine undercover, disconnect the sensor's electrical connector, and remove the mounting bolt. Replace the old O-ring with a new one during installation. The installation is the reverse of removal.
