In this guide, you will find instructions on how to reset the Mazda TPMS light.

Mazda TPMS indicator light will come on and stay illuminated if one or more of the tires on your Mazda has low air pressure. Add air to the low tire, and if the tire keeps losing air, get it repaired. 

Procedure

  1. Inflate all the tires to the recommended tire pressure. The typical tire pressure is 35 PSI. It is recommended that the tires are cooled down, but the procedure will work regardless. Recommended tire pressure for your Mazda can be found on the driver's door jamb or the fuel tank door.

TPMS stays on bur tire pressure is correct

In some cases, the TPMS warning light may come and stay on even though the tires don't need any more air, meaning they are all inflated to 35 PSI. The most common problems that can trigger the low tire pressure warning light are:

  • TPMS light on a Mazda could come on due to a defective TPMS sensor.
  • You are using a spare tire.

If you are experiencing any of the cases above, the TPMS tire pressure light will stay on even if you add air to your tires. Check the size of the tires. Make sure they all have a TPMS sensor installed.

If the tires are inflated and have a sensor, the most likely cause is a defective TPMS sensor (common problem) or a malfunction with the TPMS system, which is not a very common problem.

TPMS light flashing

If the TPMS light is flashing or the light won't go off, it could be due to a drained TPMS sensor battery or a TPMS system problem.

You can use a TPMS diagnostic scanner to troubleshoot the Mazda TPMS system and retrieve the error codes. This will allow you to troubleshoot the TPMS light yourself.
