Niterra, owner of the brands NGK and NTK, lists the six main functions of speed sensors

Company also lists main cautions and warning signs for faulty equipment

São Paulo, February 2024 – Located in the gearbox, Speed sensors are important devices for driver safety that offer accurate data about the vehicle's speed. In order to enlighten users about the usability of this component, Niterra, Japanese multinational owner of the NGK and NTK brands and specialized in components for ignition systems and automotive sensors, List the six main functions of speed sensors.

 ;

1. Precision on the instrument panel: On older cars, Speed sensors allow accurate sending of speed information to the dashboard, Eliminating the need for fault-prone cables.

 ;

2. Advanced mileage control: with functions such as TRIP A and TRIP B, Speed sensors make it possible to correctly control the mileage travelled, allowing drivers to reset the count for better trip management.

 ;

3. Improved handling with injection systems: on vehicles equipped with injection systems, Assist in adjusting injection time per load and speed, Optimising drivability.

 ;

4. Optimization of automatic transmissions: in automatic transmissions, Speed Sensors iInform the transmission module of the instantaneous speed of the vehicle, enabling proper gear selection, Contributing to a smooth and efficient ride.

 ;

5. Improved cruise control: for cars equipped with Cruise Control, known as "autopilot" in Brazil, Sensors ensure precise speed control, further enhancing this driver assistance system.

 ;

6. Aid in the operation of the ABS braking system: in the most advanced cars equipped with an ABS braking system, Speed information is provided by the wheel speed sensors, also referred to as ABS sensors, are used to monitor the speed of the vehicle, The mechanic must always evaluate the correct characteristics of each system.

Velocity Sensor Care

Some precautions are essential for vehicle speed sensors. The Variation in Sensor Drive Gear Models, According to the application and displacement of the engine, Requires the correct assessment during transmission repair. Furthermore, It is important to consider the number of pulses generated, because externally similar sensors can generate different amounts of pulses, Affecting the accuracy of speed information on the dashboard.

 ;

Even with proper attention, The driver should always check that the component is working properly. "When defective, These sensors can cause problems, such as the lack of speed information and mileage marking. Specialized automotive panel workshops can solve these issues.", afirma Hiromori Mori, Technical Assistance Consultant at Niterra do Brasil.
