NTK warns about the problems that poorly installed tires can cause in speed sensors

Tire calibration and maintenance are allies to ensure safety

of drivers

São Paulo, January 2025- Wheel Speed Sensor, popularly
known as ABS sensor, Individually monitors the rotation of each
Vehicle Wheel. This component is essential for the functioning of the system
ABS brake, helping to prevent wheel lock-up during braking
emergency. Nonetheless, for the system to operate correctly, It's
It is essential to observe some care related to tires.
When different size tires are installed on the vehicle, or by
Variation in diameter, tread width or height, There is a
Change in distance traveled with each turn of the wheel, that is, perimeter of the
tire. This discrepancy can cause several problems in the operation of the
ABS system, compromising vehicle safety.
Beyond the measures, The type of application of the tire is on land, mixed use or
load, speed index and weight it supports, must be observed.
Another important point, is that the tire is the only point of contact between the
Vehicle and the ground. Using tires in good condition is essential to ensure the
safety of vehicle occupants and other road users.
The NKT, brand of Niterra, Japanese multinational that also owns the brand
NGK and is a specialist in components for ignition systems, warning about the
difficulties that sensors face due to inconsistencies in tires and
reinforces the importance of maintaining compatibility to ensure security
of drivers.
1- Errors in the reading of speed sensors: the diversity of measures
of tires, can cause variations in the speed read on each wheel,
increasing the difference between them and generating errors in the electronic system;

2- Improper activation of warning lights on the dashboard: indicating failures in the
ABS, ESP or other systems;
3- Temporary deactivation of security systems:, such as ABS and TCS,
compromising drivability.
The importance of tire calibration and maintenance
Calibrating tires regularly is essential to avoid wear and tear
Irregular, Save fuel and ensure safety. Pressured tyres
Very low, for example, affect vehicle efficiency and can compromise
the grip and performance of electronic safety systems.
"Failures in the wheel speed sensors can lead to the ignition of
multiple warning lights on the dashboard and the deactivation of crucial systems such as
ABS, TCS and ESP", afirma Hiromori Mori, Technical Assistance consultant.
"Under these conditions, The driver loses the benefits of electronic assistance,
increasing the risk of accidents in emergency situations."
Beyond ABS Sensor, or wheel speed, Niterra presents another seven
Component models for the injection system that are available in the
aftermarket as: temperature; rotation; speed; ABS; TPS
(butterfly position); MAP (absolute pressure) and Pressure switch
oil.
