Hyundai TPMS Problems: Symptoms, Causes and How to Fix

Tire Pressure Monitoring System (TPMS) issues in Hyundai vehicles can lead to incorrect tire pressure readings, which can affect vehicle handling, fuel efficiency, and tire life. Understanding the symptoms, causes, and how to fix these problems can help maintain your vehicle’s performance and safety. Here’s a comprehensive overview: Symptoms of TPMS Problems in Hyundai Vehicles TPMS Light Stays On: A constant illumination of the TPMS light on your dashboard indicates a problem with the system or low tire pressure. TPMS Light Flashes: A flashing TPMS light at startup that continues to blink for a minute or so indicates a malfunction with the TPMS itself. Inaccurate Pressure Readings: If the TPMS is showing inaccurate tire pressures (too high or too low compared to manual checks), there might be an issue. No Response: The TPMS does not update or respond to pressure changes. Causes of TPMS Problems Dead Batteries in Sensors: Each tire’s sensor has a battery, which can die over time, leading to signal loss. Damaged Sensors: Sensors can be damaged by road hazards, during tire changes, or due to corrosion. Improper Installation: Incorrect sensor installation can cause malfunction. Tire Repairs or Replacements: Sometimes after tire repairs or replacements, sensors are not correctly reinstalled or reprogrammed. System Malfunction: The TPMS module itself may malfunction, needing diagnostic and repair. How to Fix TPMS Problems Check Tire Pressure Manually: First, ensure all tires are inflated to the correct pressure as per the owner’s manual. Reset the TPMS: Some Hyundai models allow for a manual TPMS reset via a button under the steering wheel or through the vehicle settings in the infotainment system. Refer to your owner’s manual for the specific procedure. Replace Sensor Batteries: This requires a professional as sensors need careful handling. Note that in many cases, the entire sensor is replaced since the battery is integrated. Inspect and Replace Damaged Sensors: Have a professional inspect and replace any sensors showing signs of damage or corrosion. Reprogramming: After replacing sensors or tires, reprogramming may be necessary to ensure the system recognizes the new or repaired sensors. This often requires specialized tools and should be done by a professional. System Diagnostic: If the above steps do not resolve the issue, a full system diagnostic by a professional is needed. This will identify any TPMS module issues or other system faults.
