This is the difference between the early Manifold single wire O2 sensors
(in the hot zone) and the later 3 wire (heated for quicker warm up to
operating temp) type sensors.

The farther you are from the heat of the manifold, the more you need the
heating element to get the O2 up to operating temp.

As they say- if it won't get hot, it won't work right.  :)
