O2 sensor wiring - EJ22 Lib
Posted: Fri Jun 20, 2008 2:38 pm
I have been meaning to fit my new *universal* Oxygen (O2) sensor, but want to know which was to wire it.
My new sensor is a 3 wire - black signal and 2 whites being heater ground and power.
The Liberty loom has a white (signal I think) - goes to A6 on ECU (but I get a very low voltage from the loom end with sensor not connected ~0.24V and ignition on), a yellow/red which is +12V with ignition on and a black/white which doesn't appear to give any voltage.
Now I assume that the black goes to the white loom, and the two whites go to the other two and it doesn't matter which way it goes.
Is this correct, or am I missing something? The wiring diagrams don't clearly show what the 3 wires from the loom actually are and neither does the sensor check description in the Gregory's manual.
