NTK highlights impacts of inadequate tire pressure on speed sensors

Calibration errors can generate inaccurate readings on speed sensors and affect systems such as ABS and stability control.

São Paulo, January 2026 - Correct tire inflation goes far beyond comfort and fuel economy. It also has a direct influence on the vehicle's electronic systems., like speed sensors, fundamental components for the proper functioning of security and performance technologies. Pay attention to this topic, The NAT, brand of Niterra, Japanese multinational also responsible for NGK, explains how inadequate tire pressure can impact the readings of these sensors and, consequently, the behavior of the car.

Wheel speed sensors monitor the rotation of each wheel and send this information to systems such as ABS (anti-lock braking system), Traction control, stability control and even the speedometer. When tires are inflated much lower than recommended by the manufacturer, the effective diameter of the wheel changes, modifying the rotation speed and may generate inaccurate readings. To avoid this type of interference in the functioning of electronic systems, NTK reinforces the importance of some basic care in everyday life:

1. Check tire pressure regularly: preferencialmente a cada 15 dias, as the gradual loss of air is natural and, when not corrected, can change tire diameter, affect the reading of speed sensors and compromise the functioning of electronic safety systems.
2. Always follow the vehicle manufacturer's recommendations: indicated in the manual or on the label located on the door, as each model is designed to operate at a specific pressure, ensuring the correct performance of electronic systems, in addition to the balance between security, drivability and fuel consumption.
3. Carry out the measurement with cold tires: since the heating caused by running temporarily increases the internal pressure, which can lead to an inaccurate reading and a calibration above the recommended level.
4. Also pay attention to the spare tire: in emergency situations, A spare tire with inadequate pressure can compromise safety, control of the vehicle and even interfere with the functioning of electronic systems when used.
5. Use tires with correct sizes: Another common mistake is using tires with different perimeters, distance the tire travels each lap, Always use tires recommended for your vehicle.

Impacts of incorrect calibration on security systems

Variations may result in the improper activation of security systems, irregular functioning of the ABS or stability control and even the illumination of warning lights on the dashboard. In more critical situations, Incorrect reading can compromise security, especially during sudden braking or sharp turns.

“A flat tire, affects vehicle handling and stability, This can cause the tire to come off the wheel rim., increases fuel consumption, raises tire temperature and increases tire wear. A simple precaution is to calibrate your tires regularly, in addition to bringing great benefits, makes safety systems like ABS, traction and stability control work properly. The correct functioning of these systems is based on precise information about the speed of each wheel.”, explains Hiromori Mori, Niterra Technical Assistance Consultant.

In case of more serious problems with the ABS sensor, When there is a need to replace a component, some care is essential to ensure the proper functioning of the system: make a correct diagnosis, check the application of the part in the updated catalog, clean the area before installation, respect the specified torque and conclude with a running test. On certain vehicles, It is also necessary to recognize the sensor using a scanner. Keep attention to traffling on poorly paved roads or with many loose objects, impacts to the sensor or damage to the harness (electrical cables) of the vehicle may cause a malfunction.
