Tire pressure monitoring system Mazda CX-5

The Japanese crossover is equipped with new modern electronics that ensure the safety of passengers and a high level of vehicle controllability. The greatest load during movement falls on the wheel, so each driver should check the condition of the rubber and the readings of the Mazda CX-5 tire pressure sensor before the trip. You need to be especially careful in winter, when temperature fluctuations can lead to destabilization of indicators.

Why are pressure sensors needed

Statistically, most road accidents are due to tire problems. To avoid an accident, the driver is advised to check the tire pressure of the Mazda CX-5 before each trip.

Under-inflated or over-inflated tires cause:

• loss of dynamics;
• decrease in controllability;
• increased fuel consumption;
• reduce the contact surface with the road surface;
• increased braking distance.

Modern cars are equipped with a pressure sensor that warns the driver about deviations from the norm. If such a device is not available, car owners can replace it with a pressure gauge. The electronic pressure gauge is considered the most accurate.

Types of sensors

According to the type of assembly, sensors are divided into:

1. Exterior. Made in the form of standard caps that are attached to the tire. The main advantages include low cost and ease of use. The main disadvantage is that any passer-by can easily twist this part to sell it or install it on their car. Also, when driving at high speeds, there is a risk of losing or damaging the part.
2. Interior. They are installed in the air duct through which the wheel is inflated. The design is mounted on a disk under the tire, which makes it completely invisible. The data is transmitted to the monitor or smartphone screen via Bluetooth radio channel.

Principle of operation

The principle of operation of the tire pressure monitoring system is to provide the driver with real information about the condition of the wheel. According to the method of bringing information to the car owner, sensors are:

1. Mechanic. The cheapest option. Most often they are placed outside the wheel. The indicator is determined visually. Green indicator - normal, yellow - you need to check, red - it is dangerous to continue driving.
2. Simple electronics. They produce external and internal models of sensors. The main difference is the built-in chip that transmits information to the display device.
3. New electronics. Modern fixtures (also used for CX-5 tires) are available with internal fastening only. The most expensive and reliable sensors. In addition to the pressure level, they also transmit information about the temperature and speed of the wheel.

How sensors work in the Mazda CX-5

Mazda CX-5 tire pressure monitoring (TPMS) is carried out simultaneously from all sides when the engine is started. The sensor turns on after starting the engine, turning off after a few seconds. During this time, real indicators are reviewed and compared with regulated ones. If there are no deviations, the system switches to passive tracking mode. During parking, control is not performed. The activation of the sensor while driving signals the need for immediate adjustment. After setting the indicator to the standard value, the signal lamp goes out.

The system may crash or hide a problem when:

1. Simultaneous use of different types of tires or inappropriate rim sizes Mazda CX-5.
2. Tire puncture.
3. Driving on a bumpy or icy road.
4. Drive at low speed.
5. Traveling short distances.

Depending on the diameter of the tires, the tire pressure in the Mazda CX-5 r17 should be 2,3 atm, for the R19 the norm is 2,5 atm. The indicator is identical for the front and rear axles of the car. These values ​​are regulated by the manufacturer and are indicated in the technical documentation.

Tires can deflate over time, exchanging air with the environment through the pores in the rubber. In summer Mazda CX-5 tires, the pressure increases with increasing temperature, while in winter this figure drops by an average of 0,2-0,4 atmospheres per month.

The operation of the sensors is not affected by the tires installed on the Mazda CX-5 (R17 or R19). Even when changing tires or wheels, the system automatically changes the settings and calibrates the data for the new operating conditions.

Сonclusion

Tire pressure is the key to road safety and prolongs the life of tires. Mazda CX-5 electronic TPMS system quickly informs the driver about deviations from the established standards.
