The simulator connects to the secondary. It contains instructions for building a circuit using a 555 timer chip that generates an oscillating voltage signal within the expected range to mimic the signal of a real oxygen sensor. Symtech labs intelligent oxygen sensor simulator bs intelligent oxygen sensor simulator (io2ss)
O2 Sensor Simulators - Complete Guide - MY350Z.COM - Nissan 350Z and
Your io2ss is capable of perfectly replicating most downstream o2 sensors’ signals to eliminate check.
For complete installations, cut each wire between the o2 sensor and its connector
I know this picture is ugly, but it shows you which wires connect to. Install the dummy o2 sensor (also called an o2 sensor simulator) by turning it clockwise into the exhaust just as though you were installing a regular o2 sensor. Our firm’s nissan quest oxygen sensor simulator will give you the ability to drive without catalytic converter or to install an exhaust modification, while keeping check engine light off. Detailed installation instructions included in your nissan oxygen sensor simulator /is designed to do away with o2 sensor related check engine light issues/ kit.
