Tire pressure monitoring systems (TPMS) have become a standard feature in modern vehicles, designed to alert drivers when tires are underinflated. A tire sensor fault occurs when one or more of these sensors malfunction, preventing the system from accurately monitoring tire pressure.
Common Causes of Tire Sensor Faults
Battery Failure: Over time, the battery within the tire sensor can weaken or die, leading to a fault.
Physical Damage: Sensors can be damaged due to road hazards, punctures, or improper installation.
Radio Frequency Interference: Electronic devices or external factors can interfere with the sensor’s radio frequency signal.
System Malfunction: In some cases, the TPMS itself may experience a glitch or failure.

Warning Light: A tire pressure monitoring system warning light will illuminate on the dashboard.
Inaccurate Readings: The system may display incorrect or fluctuating tire pressure readings.
No Readings: If multiple sensors are faulty, the system may be unable to provide any tire pressure information.
Diagnosing and Resolving Tire Sensor Faults
Visual Inspection: Check for any visible damage to the tires or rims.
OBD-II Scanner: Use an OBD-II scanner to read diagnostic trouble codes (DTCs) related to the TPMS.
Tire Pressure Check: Manually check the tire pressure to verify if it matches the system’s readings.
Sensor Replacement: If a sensor is faulty, it will need to be replaced. This typically involves removing the tire, dismounting it from the rim, and replacing the sensor.
System Reset: After replacing a sensor, the TPMS may need to be reset or recalibrated.
Preventing Tire Sensor Faults
Regular Maintenance: Ensure proper tire maintenance, including regular rotations and inspections.
Avoid Road Hazards: Drive carefully to minimize the risk of damage to the sensors.
Professional Installation: If replacing sensors, have them installed by a qualified technician.
Battery Replacement: If the battery in a sensor is nearing its end of life, consider replacing it proactively.
