hey whats up. So I have a code 41 check engine light sitting here tellin me I can't push vtec. I read somewhere its possible to check the o2 sensor's usefulness by unplugging the 4 wires coming from the sensor going to the ecu and measure resistance in two of the wires; a good sensor would show 10-40 ohms. I played around with it and found only .33 ohms between a heater wire and I think the ground wire, the only two wires that showed resistance at all. So ok, ill fork over a limb or two for a new one. But before I go and flub another 70 dollar sensor I would like to verify the correct wiring.
A6 o2 heater control
A25 o2 heater 12v
D14 o2 sensor signal
D22 o2 sensor ground
I need someone to Find a problem in this setup, or verify that it is correct
