  Q: How to Service and Repair the Speed Sensor on the Output Shaft on Mercury Villager?

  A:

  Service and repair operations on the Output Shaft Speed (OSS) Sensor must begin with disconnecting the battery ground cable. The service and repair of the output shaft speed sensor begins with disconnecting the electrical connector and removing the air cleaner assembly first. Begin by elevating the vehicle and afterward disconnect the LH wheel as well as its tire from the vehicle. Begin the procedure by removing both the splash shield bolt and splash shield which is located on the LH side of the vehicle. Reset the output shaft speed sensor by extracting both its bolt and sensor itself. You should start by positioning the output shaft sensor before fixing it securely with the bolt for installation. Place the splash shield in position and reinstall its bolts as well as the splash shield bolt. After putting back the LH wheel assembly with tire you should lower the vehicle while reconnecting the electrical connector for output shaft speed sensor. The last step includes putting back the air cleaner assembly. Once the battery disconnect and reconnect process is complete the vehicle needs to drive at least 16 km (10 miles) because the adaptive strategy relearning will show abnormal drive symptoms during this period. Complete the procedure by connecting the battery ground cable.
