Question A/F Guage.....Please Help....Tried Everything!!!

I just purchased a Venom Performance A/F monitor, and hooked up all coorsponding wires. I ran the sensor wire to the O2 sensor in the center pipe, and attached it to the white wire....is this correct? Because I tried the blue wire as well, and it didn't work either.

If i disconnect the sensor wire, it lights all LEDs up. When attached it stays all the way over at lean, regardless of the rpms or opperating temp.

I relocated my O2 sensor after my cat in my exhuast, because of a CEL. I have a full turbo back exhuast on my 02 WRX, and Since I started fooling with the O2 sensor, my car will run rich, and then lean out. But I really cannot tell whats going on due to the sensor not working.

Should I wire it to the ECU?? If so what wire do I need to attach the sensor wire to???

Please help.....

T.D.

hey man i had the same problem. i just bought an autometer a/f/ ratio gauge and i got the ecu pinouts to install the gauge and it didnt work. so i called autometer and asked them where it would connect to. he told that our o2 sensors are wideband (whatever that means) and that it wont read the sensor.

Most people in your situation tap the o2 wire on the ECU. It worked on both my SAFC and J&S a/f guage.
good luck!

Use a voltage meter to read while the car is on... one will read nothing, the other will read positive. The positive one should be the heater wire (unless it's the ground for the heater instead).

Ok, the O2 sensor has a plug a little back up the line... see if you can see where those black wires meet in there and see what colors the attach to on the other side of that plug.
