Ford YF1Z-7H103-AA
Speed Sensor

Repair and servicing procedures for the Output Shaft Speed (OSS) Sensor begin with removing both the catalytic converter and the heat shield. Start by removing the OSS sensor connector and proceeding to take off the OSS cover by disconnecting the connector and bolt followed by removal of the cover itself. Start with sensor OSS replacement unless the OSS cover and sensor are the only required components of the installation. Fasten the cover with the provided bolt by tightening it to 11 Nm (8 ft. lbs.) and then reattach the OSS connector. Reinstall both the heat shield followed by the catalytic converter.

The procedure to work on Output Shaft Speed (OSS) sensors starts with the removal of the OSS sensor connector and the battery ground cable. First use counterclockwise rotation of the belt tensioner to take off the drive belt before you elevate and securely position the vehicle. A proper service and repair of the Output Shaft Speed (OSS) sensor requires removing the right-hand front wheel and the right-hand front inner fender splash shield after extracting their screws and pin-type retainers. The next step involves the installation of the flywheel holding tool then torque converter inspection cover removal. When undoing the crankshaft pulley it needs to be done with a reverse thread operation. Start by disconnecting both the stator and voltage regulator connectors and remove the generator after disconnecting its mounting bolts. By reaching the sensor through the passenger side one can disconnect the connector and remove the bolt before removing the sensor cover. The last step involves removing the OSS sensor before proceeding to reassemble it in the reverse order of the removal process.

You must start service or repair of the Output Shaft Speed (OSS) Sensor by removing both the catalytic converter and heat shield from the system. Start by disconnecting the OSS sensor connector and proceed to remove the OSS cover through the removal of its connector and bolt. You should remove the OSS sensor after you have taken out its cover and connector. Install the OSS sensor first and then install the OSS cover along with the cover's bolt which should be tightened to 11 Nm (8 ft. lbs.). According to the procedure you should first attach the OSS connector and reinstall the heat shield before mounting the catalytic converter.

Professional service of the Turbine Shaft Speed (TSS) Sensor begins with elevating the vehicle to a hoist. The left-hand front wheel together with its tire needs removal. Proceed with disconnecting the TSS sensor connector before you remove the TSS sensor. The installation process concludes by performing the opposite actions which were used for removal.

Remove the necessary parts in the order indicated by the accompanying illustration and table.
