Oxygen Sensor Diagram for Redtop SR20DET |

Red Top SR20DET Oxygen Sensor Diagram If you are trying to
connect a monitoring device or gauge to your stock O2 sensor for
Air/Fuel readings, this is the pin you must use on the ECU to read it
correctly.

Note: The stock narrowband O2 sensor is highly innaccurate. I do not
reccomend using it to fine tune your engine. Get a good wideband to see
the real benefits of A/F readings.
I reccomend the Innovate LM1 Wideband |
