Steps to Turn Off Your Mazda Tire Pressure Light
Inflate each tire to the correct tire pressure stated on the sticker inside the driver side door.
Start the car.
Hold down the TPMS reset button underneath the air vent on the left side of the dash. (exclamation point with SET)
The low tire pressure telltale light will flash a few times.
Let go of the TPMS reset button.
PRO TIP: If your Mazda does not have a tire pressure reset button, after inflating each tire to the recommended air pressures, the vehicle needs to be driven for at least 5 minutes at speed exceeding 25 mph to turn off the tire light.
What Causes a Tire Pressure Warning Light to Pop Up?
Low Tire Pressure: The most common cause is low tire pressure. This can be due to a puncture, gradual air loss, or changes in temperature.
TPMS Sensor Issues: Problems with the tire pressure monitoring system (TPMS) sensors, such as a dead or low battery or sensor failure, can trigger the low tire warning light.
TPMS Malfunction: If the TPMS itself is malfunctioning, it may not be able to accurately monitor tire pressure, leading to a false warning light.
Temperature Changes: Cold weather can cause air pressure decreases, triggering the warning light. Conversely, high temperatures can increase tire pressure.
Incorrect Calibration: Incorrectly calibrated TPMS sensors or a system that hasn’t been reset after tire rotation or replacement can lead to false warnings.
Faulty Wiring or Control Module: Issues with the TPMS wiring or control module can also cause the tire system warning light to come on.
How Does Mazda Tire Pressure Monitoring System Work?
Mazda vehicles are equipped with a direct tire pressure monitoring system (TPMS), which uses sensors located in each tire to monitor air pressure levels. Each tire pressure sensor transmits tire data to the Mazda’s TPMS control module via radio signals, which then alerts the driver if any tire’s pressure is below the recommended level set by the vehicle manufacturer; Mazda. The tire pressure monitoring system then triggers a warning light on the dashboard, indicating which tire is affected and needs your attention.
How Do I Fix My TPMS on My Mazda When the Reset Didn't Work?
If your Mazda tire pressure light does not turn off after following the TPMS reset procedure, here are more options:
First, re-check each tire’s air pressure with a tire pressure gauge to make sure they are all at the exact pressure you set them to previously. If any tire has lost air, inspect the tires for leaks by spraying soapy water on the tread and around the tire beads and valve stems.
Disconnect the negative battery terminal for about a minute to reset the Mazda computer system, potentially clearing any TPMS faults and the tire monitoring system warning light.
Deflate each tire by around 10 psi, then reinflate to the inflation pressure recommended; afterward, drive for at least 10 minutes at 25+ mph.
Use a TPMS diagnostic tool to scan all 4 TPMS sensors and identify any that are malfunctioning, which is often the cause of the TPMS light or TPMS system malfunction.
Why is My Tire Pressure Light On When My Tires are Fine?
The TPMS warning light may illuminate even if the tires appear fine for several reasons:
Seasonal temperature changes can cause air pressure to decrease, triggering the warning light.
Electronic radio interference from nearby electronics or other vehicles can cause a tire warning light when nothing is actually wrong with the tires or wheels.
The system needs time to sample data before indicating a problem, so it may not instantly register a rapid tire deflation or blowout.
Factors like different tire sizes, types, wear levels, use of run-flat or studless tires, or tire repairs can affect TPMS readings.
The TPM system or on board computer may have a malfunction preventing it from detecting low pressure correctly.
Why is the TPMS Warning Light Flashing?
The TPMS warning light will flash for approximately one minute, then remain continuously illuminated if the system detects a malfunction. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. This is also known as a TPMS malfunction indicator. A flashing TPMS warning light indicates a tire pressure monitoring issue rather than an air pressure issue.
This could be due to a malfunctioning sensor, a problem with the TPMS control module, or a fault in the system’s wiring. 90% of the time TPMS malfunctions may occur due to a low or dead battery in a tire pressure sensor. It’s important to have the system checked with an OBD scan tool, by an authorized Mazda dealer, or qualified mechanic to diagnose and address the issue.
Is It OK to Drive My Mazda With Tire Pressure Light On?
It is not recommended to drive your Mazda with the tire pressure light on, as it indicates that one or more of your tires may be under-inflated. Driving on under-inflated tires can lead to reduced fuel efficiency, poor handling, and increased risk of tire failure. Stop and check your tires as soon as possible when the warning light comes on with a tire pressure gauge. Inflate them to the proper pressure listed on the tire inflation pressure label or vehicle placard found on the driver side door panel.
Do Mazda Vehicles Tell You Current Tire Pressures?
Older Mazda vehicles do not have this feature but newer Mazda vehicles equipped with a TPMS will display the tire pressure for each tire on the instrument cluster or infotainment system. This information is typically available through the vehicle’s onboard computer and can be accessed through the settings menu.
How Long Does Each Mazda Tire Pressure Sensor Last?
Mazda does not provide a specific lifespan for the tire pressure sensors. However, the sensors contain batteries, so their lifespan is limited. Factors like exposure to extreme temperatures, usage, driving conditions, and maintenance can all affect battery life. On average, TPMS sensors can last anywhere from 5 to 10 years. If a sensor fails, it will need to be replaced with a new tire pressure sensor.
Can I Disable My Mazda Tire Pressure Monitoring System?
No, you cannot legally disable the TPMS on your Mazda or any vehicle sold in the United States after 2007, when TPMS became federally mandated safety equipment. If you attempt to disable your vehicle’s TPMS by removing the tire pressure sensors from each wheel, this will result in a TPMS malfunction and the low tire pressure light to stay on.
Do I Need a TPMS Tool to Fix My Mazda TPMS?
If you are replacing tires or wheels on your Mazda, you will likely need a TPMS tool to register the new tire pressure sensor ID signal codes with the vehicle’s on board computer system. Without registering the new sensor codes, the TPMS warning light will remain illuminated.
In most cases, you will need a TPMS tool to diagnose and fix issues with your Mazda’s TPMS. This tool is used to reset the system, calibrate and troubleshoot the sensors, and check for any faults in the system.
