@EODguy, I don't know why the OBDII data shows 11v. The new data looks normal now. I also checked it with my multimeter and got some normal results: engine off 12.23v; engine running 14.01v and 14.34v when more loads are on (rear defroster, A/C max, headlights).
By the way, would a faulty gas filler cap or vacuum leak cause the O2 monitor not ready?
