Understanding TPMS Malfunction
Before we dive into the causes and solutions, let’s briefly understand what TPMS is and how it functions. TPMS is a safety feature installed in vehicles to monitor tire pressure and alert the driver if any tire is significantly under-inflated.
When the TPMS detects low tire pressure, it illuminates a warning light on the dashboard, indicating the need for immediate attention.
This feature is crucial as driving on under-inflated tires can lead to tire failure, reduced fuel efficiency, and compromised vehicle handling.
Causes of TPMS Malfunction
There are several potential causes for TPMS malfunction in Mazda vehicles. Here are some common culprits to consider:
- Faulty Tire Pressure Sensors: The tire pressure sensors are responsible for measuring the pressure in each tire. Over time, these sensors can become faulty or damaged, leading to inaccurate readings and triggering the TPMS warning light.
- Sensor Battery Depletion: The tire pressure sensors rely on batteries to operate. If the batteries in the sensors are depleted or nearing the end of their lifespan, they may not transmit accurate data to the TPMS system, resulting in a malfunction.
- Interference or Signal Loss: External factors such as electromagnetic interference or signal loss can disrupt the communication between the tire pressure sensors and the TPMS system, causing the malfunction indicator to illuminate.
- Sensor Calibration Issues: Improper sensor calibration during installation or replacement can lead to TPMS malfunctions. It’s crucial to ensure that the sensors are calibrated correctly to avoid any issues.
- Defective TPMS Module: In some cases, the TPMS module itself may be defective, preventing it from accurately detecting and signaling low tire pressure. If all other potential causes have been ruled out, a faulty TPMS module could be the culprit.
Resolving TPMS Malfunction
Now that we have identified the common causes, let’s explore the solutions to resolve TPMS malfunction in Mazda vehicles:
1. Check Tire Pressure Manually
Start by manually checking the tire pressure of each tire using a reliable pressure gauge. Compare the readings with the recommended tire pressure specified by Mazda for your vehicle.
If any tire is significantly under-inflated, inflate it to the appropriate pressure. Remember, TPMS is not a substitute for regular tire maintenance, and it’s essential to maintain correct tire pressure even if the TPMS warning light is not illuminated.
2. Inspect Tire Pressure Sensors
If the manual tire pressure check reveals that the tire pressures are correct, it’s time to inspect the tire pressure sensors.
These sensors are typically located inside the tire, attached to the valve stem, or integrated into the tire itself. Look for any signs of damage, corrosion, or loose connections.
If any sensor appears to be faulty, it may need to be replaced.
3. Replace Faulty Sensors
If you suspect that one or more tire pressure sensors are faulty, it’s recommended to replace them. Consult with a certified Mazda technician or visit an authorized service center to ensure proper installation and calibration of the new sensors.
Replacing faulty sensors can often resolve TPMS malfunctions and restore the system’s functionality.
4. Verify Sensor Battery Life
If the tire pressure sensors are functioning correctly but the TPMS malfunction persists, it’s essential to verify the battery life of the sensors.
Low battery levels can hinder the sensors’ ability to transmit accurate data. Consult with a Mazda technician to determine if the sensors’ batteries need replacement.
5. Address Signal Interference
Interference or signal loss can disrupt the communication between the tire pressure sensors and the TPMS system. To address this issue, consider the following steps:
- Ensure that there are no external devices or equipment emitting electromagnetic signals in close proximity to the vehicle.
- Check for any physical obstructions, such as metal objects or aftermarket modifications, that could interfere with the tire pressure sensor signals.
- If the interference persists, consult with a Mazda technician to diagnose and resolve the issue.
6. Calibrate Sensors Properly
During sensor installation or replacement, it’s crucial to calibrate the sensors correctly. Improper calibration can lead to TPMS malfunctions. Follow the manufacturer’s instructions or seek professional assistance to ensure accurate sensor calibration.
7. Replace Defective TPMS Module
If all other potential causes have been addressed, and the TPMS malfunction persists, it’s possible that the TPMS module itself is defective. Consult with a Mazda technician to diagnose the issue and determine if the TPMS module needs replacement.

Tips for Dealing with TPMS Malfunction
While resolving TPMS malfunctions, consider the following tips to ensure your safety and peace of mind:
- Regular Tire Maintenance: Regardless of TPMS functionality, it’s crucial to perform regular tire maintenance. Check tire pressure monthly when the tires are cold and inflate them to the recommended pressure specified by Mazda.
- Immediate Action: If the TPMS warning light illuminates, promptly check your tires to ensure they are properly inflated. Driving on under-inflated tires can lead to dangerous situations.
- Professional Assistance: If you are unsure about addressing TPMS malfunctions yourself, seek professional assistance from a certified Mazda technician or an authorized service center.
- Keep Records: Maintain a record of tire pressure checks, sensor replacements, and any TPMS-related issues. This documentation can be helpful for future reference and warranty claims.
- Educate Yourself: Familiarize yourself with your Mazda vehicle’s specific TPMS system and its operation. Understanding the system can help you troubleshoot minor issues and prevent potential malfunctions.
TPMS malfunctions can be inconvenient and concerning, but with the right knowledge and steps, they can be resolved effectively.
By understanding the common causes, implementing the appropriate solutions, and following the provided tips, you can ensure the proper functioning of the TPMS in your Mazda vehicle.
Remember, prioritizing tire maintenance and addressing TPMS malfunctions promptly is essential for your safety on the road.
Drive with confidence, knowing that you are equipped with the necessary information to handle TPMS issues in your Mazda.
