Common Causes of Mazda CX-5 Tire Pressure Monitoring System Malfunctions
The tire pressure monitoring system (TPMS) in the Mazda CX-5 is a crucial safety feature designed to alert drivers when tire pressure falls below recommended levels. However, there are instances when this system may malfunction, leading to inaccurate readings or a complete failure to notify the driver. Understanding the common causes of these malfunctions can help owners diagnose issues and take appropriate action.
One of the primary reasons for a malfunctioning TPMS is a dead or weak battery in the tire pressure sensors. Each tire is equipped with a sensor that monitors the air pressure and transmits this information to the vehicle’s onboard computer. Over time, the batteries in these sensors can deplete, especially if the vehicle is older or if the sensors have not been replaced during routine maintenance. When the battery fails, the sensor can no longer send accurate data, resulting in a warning light on the dashboard or a complete absence of readings.
Another common cause of TPMS issues in the Mazda CX-5 is the presence of a damaged or faulty sensor. Physical damage can occur due to road hazards, such as potholes or debris, which may impact the sensor’s functionality. Additionally, sensors can become corroded or worn out over time, particularly in regions where road salt is used during winter months. When a sensor is compromised, it may fail to detect tire pressure changes, leading to erroneous alerts or a non-functional system.
Moreover, improper tire installation can also contribute to TPMS malfunctions. When tires are replaced or rotated, the sensors must be correctly reinstalled and calibrated. If this process is not performed accurately, the system may not recognize the sensors, resulting in a failure to monitor tire pressure effectively. It is essential for technicians to follow manufacturer guidelines during tire service to ensure that the TPMS operates as intended.
In addition to these mechanical issues, environmental factors can also play a role in TPMS malfunctions. Extreme temperature fluctuations can affect tire pressure, and if the system is not calibrated to account for these changes, it may trigger false warnings. For instance, a sudden drop in temperature can cause tire pressure to decrease, leading to alerts even if the tires are not significantly under-inflated. Conversely, if the system is not sensitive enough, it may fail to alert the driver when tire pressure is genuinely low.
Furthermore, software glitches within the vehicle’s onboard computer can lead to TPMS malfunctions. Just like any electronic system, the TPMS relies on software to interpret data from the sensors. If there is a bug or an error in the software, it may misread the information being sent by the sensors, resulting in incorrect alerts or a complete failure of the system. Regular software updates and diagnostics can help mitigate these issues.
Lastly, a lack of regular maintenance can contribute to TPMS problems. Tire pressure monitoring systems require periodic checks to ensure that all components are functioning correctly. Neglecting these checks can lead to undetected issues that may compromise the safety and performance of the vehicle.

Using a reliable tire pressure gauge, ensure that each tire is inflated to the manufacturer’s recommended pressure, which can typically be found on a sticker located on the driver’s side door jamb. If any tire is under-inflated, inflate it to the correct pressure and observe whether the TPMS light resets after a short drive. If the light remains on, it may indicate a deeper issue.
In addition to checking tire pressure, it is important to inspect the tires for any visible damage, such as punctures or sidewall bulges. Damage to the tires can affect the TPMS sensors, leading to inaccurate readings or system failure. If any damage is detected, it is advisable to consult a professional for repair or replacement. Furthermore, it is worth noting that tire rotation can also impact the TPMS. If the tires have been rotated recently, the system may need to be recalibrated to recognize the new positions of the sensors. This recalibration process can often be performed by a dealership or a qualified mechanic.
Another potential cause of a non-working TPMS is a dead or malfunctioning sensor. Each tire is equipped with a sensor that monitors tire pressure and communicates with the vehicle’s onboard computer. Over time, these sensors can fail due to battery depletion or physical damage. If the sensors are suspected to be the issue, a diagnostic tool can be used to read the TPMS codes and identify any faulty sensors. In some cases, replacing a sensor may be necessary to restore the system’s functionality.
Moreover, environmental factors can also play a role in the performance of the TPMS. Extreme temperatures, whether hot or cold, can affect tire pressure and, consequently, the accuracy of the monitoring system. It is advisable to regularly check tire pressure during seasonal changes to ensure that the TPMS is functioning correctly. Additionally, if the vehicle has been exposed to water or moisture, it may lead to corrosion of the sensor connections, which can disrupt communication between the sensors and the vehicle’s computer.
In conclusion, troubleshooting a non-working tire pressure monitoring system in a Mazda CX-5 involves a systematic approach that includes checking tire pressure, inspecting for damage, recalibrating after tire rotation, and assessing the condition of the sensors.
