Diseño y Construcción de un Circuito Electrónico para la Evaluación del Funcionamiento del Cuerpo de Aceleración Electrónico (ETB) y el Pedal de Aceleración Electrónico (APP) en el vehículo Renault Logan Crossover con Motor H4M

Abstract

This research is developed in the field of automotive electronics, specifically in the diagnosis of the Electronic Throttle Body (ETB) and the Accelerator Pedal Position (APP), which are essential components in modern vehicle acceleration control systems. The general objective was to design and implement an electronic circuit capable of verifying the proper operation of the ETB and APP in a Renault Logan Crossover equipped with an H4M engine, as an alternative to traditional diagnostic tools. Methodologically, the study was carried out in three phases: system analysis and planning, electronic circuit design and implementation, and experimental validation through controlled testing. The prototype was integrated into the vehicle's acceleration system to capture and process signals in real time. The results demonstrated that the device operates in a stable and reliable manner, allowing accurate visualization and analysis of electrical signals, facilitating fault detection and reducing diagnostic time. It is concluded that the proposed system represents a technically viable and low-cost tool that can improve efficiency in automotive service processes and serve as a didactic resource in technical education.
