How to Replace a Speed Sensor on a 2002 Ford Explorerby Allen Moore
The Ford Explorer relies on a speed sensor to provide the computer with speed information. The computer uses this information to shift the transmission, and to supply the instrument cluster with the vehicle speed for use with the speedometer and odometer. If the speed sensor fails, the transmission will shift poorly and the speedometer will fail to register correctly, if it registers at all.
Drive the front wheels of the Explorer onto the ramps. Set the parking brake and place the wheel chocks behind the rear wheels.
Climb under the Explorer below the driver’s door. Locate the speed sensor, which mounts on the driver’s side of the transmission. Unbolt it using the 10mm box wrench.
Pull the sensor out of the transmission and disconnect the sensor’s wiring harness from the Explorer’s main wiring harness by hand.
Bolt in the new speed sensor with the 10mm box wrench. Plug the new sensor’s wiring harness into the Explorer’s main wiring harness by hand.
Climb out, move the wheel chocks and drive the Explorer off the ramps carefully.
