Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle's battery to avoid electrical shorts.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench.

2. Check and Replace Speed Sensor

Locate the speed sensor, typically found near the transmission or differential.
Remove any covers or shields obstructing access to the speed sensor.
Disconnect the electrical connector from the speed sensor.
Remove the speed sensor using the appropriate socket.
Inspect the old speed sensor for damage; if faulty, install a new speed sensor.
- Torque the new sensor to manufacturer's specifications.
Reconnect the electrical connector and any covers removed.

3. Inspect and Repair Wiring

Use a multimeter to check for continuity in the wiring harness connected to the speed sensor.
Look for frayed wires, corrosion, or loose connections. Repair or replace as needed.
Ensure that all connectors are fully seated and locked.

4. Reconnect Battery and Test

Reconnect the vehicle's battery.
Clear any stored error codes using the OBD-II scanner.
Start the vehicle and check if the speedometer is functioning correctly.
