Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Gather necessary tools and parts.

2. Inspect and Replace Vehicle Speed Sensor

Tools Required: Socket set, multimeter, OBD-II scanner
Locate the vehicle speed sensor, typically found on the transmission.
Remove the mounting bolt(s) securing the sensor using a socket wrench.
Carefully disconnect the sensor's electrical connector.
Remove the old sensor from its mount.

3. Install New Vehicle Speed Sensor

Apply a light coat of transmission fluid to the O-ring of the new sensor to ensure a proper seal.
Position the new sensor in the mounting location and secure it with the bolt(s).
Reconnect the electrical connector ensuring a snug fit.

4. Reconnect Battery and Verify

Reconnect the negative terminal of the battery.
Start the engine and allow it to idle.
Use the OBD-II scanner to check for any remaining fault codes.
Take the vehicle for a short test drive to ensure proper operation and that the check engine light does not reappear.
