Mazda CX 5 Tire Pressure Light Keeps Coming On (reasons + troubleshooting)
Mazda CX 5 tires have a pressure sensor inside them to monitor the pressure condition and provide warning through the dashboard light when required. But sometimes it can keep coming on even when the tires are fine.
Mazda CX 5 Tire Pressure Light Keeps Coming On can occur due to faulty sensors, air leakage, or lack of sufficient air pressure. Though the first thing to check when this happens is to check the tire pressure, if the problem is not within the pressure, maybe it’s resulting from faulty sensors.
From resetting the pressure monitoring system to replacing the sensors, there can be many solutions to this particular problem depending on the situation. So, to have an overall idea about this problem and its solution, this article is going to be the perfect resource.

3 common reasons why Mazda CX 5 Tire Pressure Light Keeps Coming On
There are basically three primary reasons behind the pressure light coming frequently from Mazda CX 5. Here, I’m mentioning them one by one.
- Completely deflated tires:
There is a sensor used inside the tire to monitor the air pressure. This is called the Tire Pressure Monitoring System or TPMS in short. When there is no air inside the tire, the air pressure will be null. As a result, the TPMS will show a warning light as a safety mechanism.
- Leakage in the tire:
If the tires get leaked, the air will blow out of the tires due to the pressure difference. The sensor inside the tire will observe this phenomenon and thus activate the pressure warning light.
- Damaged TPMS:
Last but not least, a damaged TPMS can also cause the pressure light to come on. Any faults in the wiring, dead battery, or damaged sensor can also be the reason.
Though sometimes the sensor can work abnormally which may result in the illumination of pressure light, it can be fixed after resetting. But if the damage to the sensor is not permanent, then in most cases it needs to be replaced.
How do you turn off the warning light on Mazda CX 5?
To turn off the warning light of the Mazda CX 5, you can follow any of the following methods.
- The very first thing to do when the light comes on is to check the tire pressure. If you notice any fluctuations in any of the tires, inflate or deflate them properly. When the pressure will be within proper limits, the light should go off automatically.
- Turn off the engine as well as the vehicle and give it a rest. Then start the car without starting the engine and wait for some minutes. Meanwhile, the pressure monitoring system will be calibrated and thus the light should also go off.
- If none of the above works, then you may need to reset the whole pressure monitoring system to overcome this issue. There are several methods of doing this. Later in this article, I’ll explain how you can restart the pressure light.
How do you reset the warning light on Mazda CX 5?
Resetting the pressure warning light of the Mazda CX 5 is really easy and only needs some clicks on a dedicated button.
In many vehicles, you may need to reset the system manually. This can be done by restarting the car or the TPMS. But in modern vehicles like Mazda CX 5, there is a dedicated button under the steering wheel for resetting the pressure warning light.
All you have to do is to navigate to the maintenance option on your dashboard. Then look for the “Oil change” option and select “Reset”. The warning light will blink twice and then go off and there will be a horn beeping sound too. That means the resetting is done.

Does Mazda CX 5 have TPMS sensors?
Yes, of course. TPMS or tire pressure monitoring system is one of the most important parts of the whole automobile in recent years.
This module observes the internal air pressure of tires and sends data to the electrical control unit (ECU). If the pressure is not within proper limits, it will illuminate the warning light and thus you can take necessary actions.
So, you see how important it is to have a TPMS module in vehicles. That’s why Mazda CX 5 also comes with this pressure monitoring setup.
Where is the TPMS reset button on Mazda CX 5?
The TPMS or tire pressure monitoring system reset button is under the steering wheel of the Mazda CX 5.
Like most other vehicles, in Mazda CX 5 the reset button is also beside the dashboard. Though the position can vary a little with the particular model of Mazda CX like 2013 or 2015, the general location is almost the same. Under the steering wheel, a tiny button can be used to navigate through the menu or reset the TPMS.
Still, if you can’t find the reset button, check the owner’s manual. Generally, most people ignore this due to a lack of time or interest. But it is highly recommended to read the manual before taking any repair or maintenance of your vehicle.
frequently asked questions (FAQs)
The tire pressure for Mazda CX 5 is 34 psi for a tire with a 17-inch wheel diameter and 36 psi for a 19-inch one. But remember, this value is considered as standard and can vary depending on your requirements. For other models like Mazda CX 9, the pressure value will be different.
The exclamation mark generally refers to an under-inflated tire. Sometimes, on your car dashboard, you may see an exclamation mark under a horseshoe-type sign. This mainly indicates that one or more of the tires are low on pressure and need to re-inflate. When the pressure is increased to the recommended value, the mark will go out.
Each time you start the vehicle, the tire pressure light will come on and blink two times and then go off. This means the TPMS is properly activated and calibrated. If the light doesn’t go off or keeps blinking then the TPMS is not working properly.
Verdict
Mazda CX 5 tire pressure light is an indication of the pressure condition inside the tires. If it’s coming on frequently, it means the pressure is not within recommended limits.
In that case, resetting the sensor can solve the issue. However, if the pressure monitoring system is faulty or the sensor is damaged, then resetting may not be a solution. Then you may need to replace the whole pressure monitoring system to overcome the problem.
Before ending, I would like to remind you once again to read the owner’s guide before taking any steps. Otherwise, a simple problem can turn into a disaster just because of taking the wrong steps.
