About this document
DIY Oxygen Sensor Simulator Guide by Дејан Петровић is a document available to read on EtoBox.
This document provides instructions for building an oxygen sensor simulator that can fool an OBD-II system into thinking a catalytic converter is functioning properly. It describes how OBD-II systems use two oxygen sensors, one before and one after the catalytic converter, to monitor exhaust gas content. The simulator builds an oscillating signal generator using a 555 timer chip to output the correct frequency and voltage to mimic a functioning oxygen sensor after a catalytic converter. Precise testing was
