NTK points out the four main functionalities of TPS sensors

Also known as throttle position sensors, can cause problems with acceleration and irregularities during the idling period

The NKT, brand of Niterra, Japanese multinational that also owns the NGK brand, which specializes in components for ignition systems, Reinforces the importance of throttle position sensors (Throttle Position Sensor - TPS) for engine functionality and fuel injection system.

TPS sensors are essential for monitoring the position and speed of change of the throttle throttle position. Its information is useful for engine control strategies, including idle speed adjustment, Rapid acceleration, Injection cuts during engine braking and adaptation of torque and power according to the driver's demand. Below are the four main functions of this component.

1. Throttle position indication
2. Throttle rest position indication

3.Butterfly position indication 100% open

4. Throttle position speed display

"The impact of the TPS sensor on throttle response and vehicle acceleration is significant. On vehicles with throttle cables, TPS provides information to the injection module, allowing you to identify the position of the throttle and its travel speed. This directly influences the drivability of the vehicle.", afirma Hiromori Mori, Technical Assistance Consultant at Niterra do Brasil.

Impacts of a Faulty TPS Sensor

Usually, TPS sensors show progressive wear and tear with use, which can lead to failures in its operation and lead to symptoms that directly affect the performance of the engine. Among the most common signs are failures in accelerations, especially in a specific rotation range, lack of or irregularities in idling, oscillations in engine speed and lack of vehicle performance.

These problems can result in a difficulty controlling the acceleration of the engine or even failures in its operation, affecting the vehicle's drivability and compromising fuel efficiency. Furthermore, at the time of maintenance, Incorrect adjustment of the throttle cable can also trigger the throttle unintentionally due to engine vibration, which contributes to greater inefficiency in fuel consumption and overall vehicle performance.

"Due to potential complications arising from lack of maintenance or mechanical problems, Drivers should remain vigilant for signs of faults in their vehicles and perform the service regularly, preferably with a trusted professional. You are the one who knows your vehicle's behavior best, If you notice different performance, Seek professional help", complements Mori.

NTK revolutionizes the aftermarket with its throttle position sensors, Equipped with state-of-the-art electronic sensor technology that makes them suffer no wear and tear problems with continuous use. The brand also has lines made up of seven other different sensors, such as oxygen sensors, Fuel level, Coolant temperature, ABS, rotation, Speed & MAP (absolute pressure).
