Innovate WBO2 sensor question.

[69427]

I just removed the sensor from the exhaust, as I'm disassembling things on the car in the naive hope that ARP will eventually ship me the damn head studs so I can finally finish the new engine and get it into the car. I was looking at the sensor, and I don't see an external oxygen reference port. How does this thing calibrate itself, or provide for a source for the oxygen pumping during actual engine testing?

thanks,
Mike

With my LC-1 you have to remove it from the pipe and calibrate in ambient air.

I thought a normal O2/stock sensor did that automatically via something about 1/2 the crystal being out in the air?? hence the metal cover over the stem??
