Why is the speedometer not working on my Ford Excursion?

Reasons for Ford Excursion Speedometer Not Working
The speedometer in a Ford Excursion may stop working due to various reasons, including issues with the speed sensor, instrument cluster, or electrical components. Here are some common causes and potential solutions:
1. Faulty Speed Sensor: The speedometer is driven by speed sensors, and a malfunction in these sensors can lead to the speedometer not working. This can also trigger the check engine light. Testing the cruise control can help determine if the issue lies with the speed sensor itself.
2. Instrument Cluster Issues: A malfunctioning instrument cluster can cause the speedometer to stop working. If the odometer or speedometer stops working on the instrument cluster, it may need to be fixed or replaced.
3. Electrical Problems: Electrical issues, such as wiring problems or a faulty speedometer head, can also contribute to a faulty speedometer.
4. Tire Size Calibration: In some cases, if the vehicle’s tire size has been changed, it can affect the accuracy of the speedometer. Attempting to calibrate the speedometer to match the new tire size may be necessary.
5. Vehicle Speed Sensor (VSS) Malfunction: The VSS may be the source of the problem, and diagnosing whether it’s the VSS, speedometer, or an electrical issue can help pinpoint the cause of the malfunction.
It’s important to have the vehicle checked by a mechanic to diagnose and address the specific issue causing the speedometer to not work properly. Driving a vehicle with a non-functioning speedometer can increase the risk of accidents and should be avoided until the issue is resolved.
If you’re experiencing issues with your Ford Excursion’s speedometer, it’s recommended to seek professional assistance to diagnose and address the problem for safe driving.
