Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is off.
Tools required:
- OBD-II scanner
- Multimeter
- Socket set
- Torque wrench
Safety warnings: Disconnect the battery before beginning repairs.

2. Remove the Speed Sensor

Locate the vehicle speed sensor, usually found on the transmission casing.
Disconnect the electrical connector from the speed sensor.
Remove the retaining bolt(s) securing the speed sensor using a socket set.
Gently pull out the speed sensor from its mounting hole.

3. Inspect and Replace

Examine the old speed sensor for signs of wear or damage.
If the sensor is faulty, replace it with a new one. Ensure the new sensor matches the specifications for the vehicle.
Apply a small amount of dielectric grease to the O-ring of the new sensor to ensure a good seal.
Insert the new sensor into the mounting hole, aligning it properly.

4. Reinstall and Connect

Secure the speed sensor with the retaining bolt(s) and tighten to the manufacturer's torque specifications.
Reconnect the electrical connector to the speed sensor.
Reconnect the vehicle's battery.

5. Clear Codes and Test

Use the OBD-II scanner to clear the P0500 code from the ECU.
Start the vehicle and conduct a test drive to ensure the speedometer functions correctly and the check engine light does not reappear.
