Tire sensors play a vital role in monitoring tire pressure and alerting drivers to any irregularities. Tire sensor faults can manifest in various ways, including illuminated warning lights on the dashboard, inconsistent tire pressure readings, and reduced vehicle handling and stability.
Identifying and addressing these faults is essential to prevent potential safety hazards.
Tire Sensor Fault Description
A tire sensor fault refers to a malfunction or issue with a tire pressure monitoring system (TPMS) sensor installed on a vehicle’s tire or wheel.
Tire sensors are electronic devices that monitor and transmit real-time tire pressure data to the vehicle’s onboard computer. These sensors play a crucial role in ensuring optimal tire performance, safety, and fuel efficiency.
Common Tire Sensor Fault Symptoms
- Illuminated TPMS Warning Light:The most common symptom of a tire sensor fault is the illumination of the TPMS warning light on the vehicle’s dashboard.
- Inaccurate Tire Pressure Readings:Malfunctioning tire sensors can provide inaccurate or inconsistent tire pressure readings, leading to incorrect tire inflation and potential safety hazards.
- Reduced Fuel Efficiency:Underinflated tires caused by faulty tire sensors can increase rolling resistance, resulting in reduced fuel efficiency.
- Premature Tire Wear:Incorrect tire pressure due to sensor faults can lead to uneven tire wear, reducing tire lifespan and compromising safety.
- Poor Vehicle Handling:Faulty tire sensors can affect the vehicle’s handling and stability, especially during cornering or sudden maneuvers.
Causes of Tire Sensor Faults
Tire sensor faults in Ford Fusion vehicles can stem from various causes, including:
Tire Pressure Variations
Significant fluctuations in tire pressure, either over-inflation or under-inflation, can disrupt the sensor’s ability to accurately measure pressure. Over-inflated tires increase pressure beyond the sensor’s operating range, while under-inflated tires may cause the sensor to misread the pressure.
Mechanical Damage
Physical damage to the tire sensor or its components, such as punctures or cuts, can impair its functionality. This damage may occur during tire changes, curb impacts, or other road hazards.
Electrical Issues
Electrical faults within the sensor or its wiring harness can disrupt communication with the vehicle’s control module. Corroded or loose connections, faulty wiring, or a damaged sensor unit can lead to sensor malfunctions.

- Multimeter: To check electrical continuity and voltage levels in the tire sensor circuit.
Diagnostic Steps
The diagnostic steps for tire sensor faults in Ford Fusion vehicles include:
- Verify tire pressure: Manually check tire pressure using a tire pressure gauge and compare it to the recommended tire pressure specifications.
- Inspect tire sensor: Examine the tire sensor for any visible damage or corrosion that may affect its functionality.
- Read diagnostic codes: Use a TPMS scan tool to retrieve any diagnostic codes related to tire sensor faults. These codes provide specific information about the nature of the fault.
- Interpret diagnostic codes: Refer to the Ford Fusion service manual or online resources to interpret the diagnostic codes and identify the corresponding fault.
- Perform electrical tests: Use a multimeter to check electrical continuity and voltage levels in the tire sensor circuit, ensuring proper power supply and signal transmission.
- Replace faulty sensor: If the diagnostic procedures indicate a faulty tire sensor, replace it with a new one following the manufacturer’s recommended procedures.
- Tire pressure gauge
- Tire repair kit or replacement tire sensor
- Jack and jack stands
- Lug wrench
- Tire sealant (optional)
- Identify the faulty tire sensor using a tire pressure gauge or a diagnostic tool.
- Jack up the vehicle and secure it with jack stands.
- Remove the lug nuts and detach the flat tire.
- Inspect the tire sensor for any visible damage or leaks.
- If the sensor is damaged beyond repair, replace it with a new one.
- If the sensor is repairable, apply tire sealant to the leak and reattach the sensor to the tire.
- Reinstall the tire, tighten the lug nuts, and lower the vehicle.
- Reset the tire pressure monitoring system (TPMS) to acknowledge the new sensor.
- Regularly checking tire pressure using a tire pressure gauge.
- Inspecting tire sensors for any signs of damage or corrosion.
- Cleaning tire sensors and the surrounding area to prevent dirt and debris buildup.
- Replacing tire sensors as recommended by the manufacturer or when they fail to function properly.
- Increased risk of tire blowouts
- Reduced fuel efficiency
- Premature tire wear
- Impaired handling and stability
- Reduced effectiveness of stability control and anti-lock braking systems
- Low Tire Pressure:Check tire pressure using a reliable tire pressure gauge. If pressure is low, inflate tires to the recommended level.
- Faulty Sensor:Replace the faulty sensor. Refer to the vehicle’s service manual for specific instructions on sensor replacement.
- Interference:Eliminate any sources of interference, such as metal objects or electronic devices, near the tire sensor.
- Damaged Wiring:Inspect wiring for any cuts, breaks, or corrosion. Repair or replace damaged wiring as needed.
- Battery Failure:Replace the battery in the tire sensor. Use a high-quality battery specifically designed for tire sensors.
- Reset the tire pressure monitoring system (TPMS) after addressing the fault. Refer to the vehicle’s owner’s manual for specific instructions on TPMS reset.
- If the TPMS warning light remains illuminated after troubleshooting, consult a qualified mechanic for further diagnosis and repair.
- Regularly check tire pressure and inspect tire sensors to prevent future faults.
