General Oxygen sensor question No Volvo content..

I know you know what you said here, but I'm not sure. Can you be a little more explicit?

The two brown wires on the sensor are the heater wires. I had all four wires of the sensor plugged into connector lead and then hooked my positive meter lead to first one brown wire and then the other brown wire while the negative lead of the meter was to ground... I was able to read 13+v from the first brown wire and .46v from the other. The .46 reading threw me, but then I have confessed my lack of understanding of electron behavior to you before.

I did not realize the heater would work with a simple “key on”; I thought the engiine had to be running for the heater to get power. I was wrong as I just checked it after seeing your response. I will do a little resistance checking tomorrow.

Thanks for your response.

Randy
