Lincoln CC3Z-7H103-A Output Shaft Speed Sensor

It is used only for models with an automatic transaxle. To carry out this, start by removing the cable which connects it to the negative post of the battery. Subsequently, lift the front-side of the car and place it on supports using jackstands. Lower left splash shield: unbolt first. Find the OSS sensor mounted on the left hand side of the transaxle and snap off the electrical connection on it. OSS sensor retaining bolt is to be unbolted and OSS sensor is to be extracted. Make sure to take out the prior O-ring of the OSS sensor and then properly dispose its usage and in its place, use a new O-ring while fixing. The process of installation is the opposite of that for removal, with emphasis to the correct torque applied to the retaining bolt. Upon connecting the battery again, the PCM is forced to learn the best way on how to return back to its normal idle and fuel trim for driveability and performance to function properly.

There are two speed sensors in the vehicle.

No, you cannot replace the speed sensors in the 6-speed automatic transaxle at home. The speed sensors are integral components of the transaxle assembly and cannot be separately replaced. If replacement is necessary, the entire transaxle assembly must be replaced, and it requires professional expertise and equipment.

To repair the OSS sensor, you should take it to your local dealer or other qualified repair shop.

Attach a length of wire to the sensor's electrical connector and guide it through the transaxle case. Pull the sensor's wiring harness through the case and plug the electrical connector into its terminal on the valve body.
