o2 sensor heater power

[Huw Powell]

According to my fuse box diagram, the OXS heater voltage supply comes
from the fuel pump relay via fuse 13.  (But I could be terribly
wrong...)  the ground could be anywhere since I didn't bother to look it
up.  Try measuring open ckt voltage to a good ground to see if the
ground might be implicated.
