The 2018 Mazda 3 uses an indirect tire pressure monitoring system (TPMS). This system lacks physical sensors in the tires. Instead, it tracks tire pressure by monitoring the wheels’ rotation speed through the ABS system. Regularly checking tire pressure is crucial for effective vehicle maintenance.
To check the tire pressure sensors, first ensure your tires are cold, as heat can alter pressure readings. Use a tire pressure gauge to measure the air pressure in each tire. Compare these readings with the recommended pressure listed on the driver’s door jamb. If the pressure is too low or too high, adjust it accordingly.
If the TPMS warning light remains illuminated, this may indicate a fault in the sensor, or one or more tires may still be under-inflated. In that case, it is advisable to consult a professional mechanic for diagnosis and potential sensor replacement.
Next, we will explore how to reset the Tire Pressure Monitoring System after checking or adjusting the tire pressures.

Why Are Tire Pressure Sensors Essential for the 2018 Mazda 3?
Tire pressure sensors are essential for the 2018 Mazda 3 because they monitor tire pressure continuously. These sensors alert drivers when tire pressure falls below safe levels. This information is crucial for maintaining optimal vehicle performance, fuel efficiency, and safety.
According to the National Highway Traffic Safety Administration (NHTSA), tire pressure monitoring systems (TPMS) are designed to warn drivers when tire pressure is significantly low. This helps prevent accidents and improves fuel efficiency.
The underlying reasons for the importance of tire pressure sensors include safety, vehicle stability, and tire longevity. Low tire pressure can lead to tire blowouts, decreased traction, and longer stopping distances. The sensors actively detect tire pressure, providing real-time information to the driver. This encourages timely action, such as inflating tires or replacing them.
Technical terms include tire pressure monitoring systems (TPMS) and direct/indirect TPMS. Direct TPMS uses sensors inside each tire to measure pressure. Indirect TPMS monitors the rotational speed of the tires through the vehicle’s anti-lock braking system (ABS) to detect pressure loss.
Mechanisms involve the sensors sending data to a central control unit. When pressure drops below a predetermined threshold, the system triggers a warning light on the dashboard. This immediate feedback enables drivers to address the issue before it escalates.
Specific conditions that contribute to tire pressure loss include temperature changes, punctures, and under-inflation. For example, cold weather often decreases tire pressure, as air contracts in lower temperatures. A driver may notice the TPMS warning in winter, signaling the need to check tire inflation levels. Regular maintenance and checks can prevent many of these issues, ensuring a safe driving experience.
