How to reset Mazda Tire Pressure Sensor TPMS Light
In this tutorial, we will show you how to reset 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.
Mazda TPMS Light Reset Instructions
Inflate all the tires to the recommended tire pressure. The optimum tire pressure is 35 PSI. It is recommended that the tires are cooled down, but the procedure will work regardless. We would recommend that you use a digital tire pressure gauge to check the tire pressure.
Turn on the ignition. If you have keyless start Mazda, press the Start/Stop button but don't press the brake pedal. All the instrument cluster lights including the TPMS warning light (tire with exclamation symbol) will turn on.
Press the TPMS switch on the left side of the dash next to the steering wheel. Continue to hold the TPMS switch pressed until you see the TPMS flashes twice.
Soon after the TPMS light flashes, you will hear a beep. This is a confirmation that the TPMS light on your Mazda has been reset.
TPMS light came on in my Mazda. What does it mean?
It generally means that one of your tires is losing air. Inspect all the tires. Add air to the tire that is low and if necessary get it repaired. Especially if the TPMS keeps on coming on after a few days.
Why is Mazda TPMS on when 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.
Mazda TPMS light flashing, the light won't go off
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 problem with the TPMS system.
You can use a TPMS diagnostic scanner that is able to troubleshoot Mazda TPMS system and retrieve the error codes. This will allow you to troubleshoot the TPMS light yourself.
