I need a small favour...Can someone with an OBD-II reader let me know the voltage they are seeing on the secondary O2 sensor during lean burn (5 speed only)? I have a feeling that I shouldn't be seeing 0 volts...

Thanks!

I have some saved data here from when I was diagnosing my #1 o2 sensor failure. The #2 o2 sensor does appear to go to zero during lean burn. As a side note, my #1 o2 sensor would work for a little while and then get pinned high. I replaced the sensor and have not had any more problems.
