My meter was indicating a lean mix until I replaced the o2 sensor.

The white wires are for the heating element. Most likely to be 0v on one white wire and 12-14v on the other. The black wire is definately the signal. Unless it is a universal sensor incorrectly re wired.

not sure about the readings but 440's on a vf22 @ 1.1bar should be plenty up to it
