Ford vehicles, like many modern cars, are equipped with a Tire Pressure Monitoring System (TPMS) that keeps track of your tire pressure to ensure safe driving. If the system detects an issue, a “Tire Sensor Fault” warning will appear on the dashboard. This warning can occur for several reasons, from low tire pressure to faulty sensors. The good news is that fixing this issue is usually straightforward. In this article, we will discuss the potential causes and step-by-step solutions to resolve a Tire Sensor Fault in Ford vehicles.
Common Causes of Tire Sensor Fault in Ford Vehicles
There are a few common reasons you might see a Tire Sensor Fault warning in your Ford vehicle:
- Low Tire Pressure: The most frequent cause is a simple one—your tire pressure may be too low in one or more tires, which causes the system to detect an imbalance.
- Damaged Tire Sensors: If the sensors located inside the tires become damaged, they can no longer send accurate data to the vehicle’s computer, resulting in a fault.
- Weak Sensor Battery: The TPMS sensors in each tire are powered by a small battery that usually lasts for several years. If the battery is weak or depleted, the sensor may not function properly.
- Radio Interference: Occasionally, external radio frequencies or signals from other electronics can interfere with the TPMS, causing a fault to appear.
- Recent Tire Service: If your tires were recently rotated, changed, or serviced, a sensor might have been incorrectly calibrated or damaged during the process.
Steps to Fix Tire Sensor Fault in Ford Vehicles
Here are a few steps you can follow to fix a Tire Sensor Fault in your Ford vehicle:
1. Check Tire Pressure
The first and easiest solution is to check the tire pressure in all four tires. To do this:
- Use a tire pressure gauge to manually check the pressure in each tire.
- Compare the current tire pressure to the recommended pressure level, which is usually found on a sticker inside the driver’s door or in the vehicle manual.
- If the pressure is low, inflate the tires to the recommended level.
Once you’ve adjusted the tire pressure, drive the vehicle for a few miles. The system should automatically recalibrate, and the fault message should disappear.
2. Reset the TPMS System
If checking and adjusting the tire pressure doesn’t resolve the issue, you might need to reset the TPMS system. Here’s how you can reset it in most Ford vehicles:
- Turn the key to the On position without starting the engine.
- Use the buttons on the steering wheel to navigate to the Settings or Vehicle Settings menu in your instrument cluster.
- Find the Tire Pressure Monitoring option, then select Reset TPMS.
- Follow the on-screen prompts, then drive your vehicle for about 10-15 minutes at speeds above 20 mph to allow the system to recalibrate.
If the reset is successful, the Tire Sensor Fault warning should clear from the dashboard.
3. Inspect Tire Sensors for Damage
If the fault persists, inspect the sensors themselves. Tire sensors are located inside the tire, attached to the valve stem. Physical damage can occur during tire changes, rotations, or when driving over rough terrain.
If you notice any visible damage to the sensor or valve stem, it’s likely the sensor will need to be replaced. Since replacing a tire sensor requires professional equipment, it’s recommended to visit a certified Ford dealership or a trusted mechanic to handle the repair.
4. Replace Sensor Battery
The sensors inside your Ford’s tires are powered by small, non-replaceable batteries. When these batteries deplete, the entire sensor will need to be replaced. Sensors typically last between 5 and 10 years, so if your vehicle is older or has high mileage, this could be the cause of the fault.
Again, replacing a tire sensor is a job best left to a mechanic or a Ford dealership.
5. Check for Software Updates
Occasionally, a software glitch in the vehicle’s onboard system can cause a Tire Sensor Fault message to appear. Ford frequently releases software updates that can address bugs and improve the performance of the TPMS. Check with your local Ford dealer or use Ford’s SYNC system to ensure that your vehicle’s software is up to date.
Preventing Future Tire Sensor Faults
- Regular Tire Pressure Checks: Make it a habit to check your tire pressure at least once a month, especially during temperature changes when tire pressure can fluctuate.
- Proper Sensor Maintenance: When getting tires replaced or rotated, ensure that the TPMS sensors are carefully handled and properly recalibrated.
- Routine Service: Have your tire sensors inspected during routine vehicle maintenance to catch any potential issues early.
- Stay Updated: Keep your vehicle’s software up to date to prevent system bugs from affecting the TPMS.
Conclusion
While a Tire Sensor Fault warning in a Ford vehicle can be concerning, it’s often a minor issue that can be fixed with simple troubleshooting. By checking your tire pressure, resetting the TPMS, and inspecting for sensor damage, you can resolve the issue and get back on the road confidently. If the problem persists, visiting a Ford-certified service center will ensure that the sensor is repaired or replaced correctly.
