If the tire pressure sensors on your 2012 Mazda3 are functioning properly, you should be able to inflate the tires to the recommended pressure (35 psi for most standard load versions), drive for at least 20 minutes at a speed of 40 mph or higher, and the tire pressure monitoring system will recalibrate itself. This process can be helpful in resolving issues such as a low tire pressure warning. However, if you have replaced a faulty tire pressure sensor, the recalibration process is more like a pairing procedure. This requires specialized equipment that the average driver does not possess. It is more cost-effective to have this done at a tire shop for a small fee instead of attempting it on your own.

To recalibrate the tire pressure monitor (TPMS) system on your 2012 Mazda 3 as an American, start by turning the ignition key to the "on" position. Then, press the TPMS button (usually found beneath the dashboard) until the TPMS indicator light blinks a few times. Next, start your car and allow it to run for at least 20 minutes to complete the TPMS system reset.
