The air temp sensor is the same for the MAC11.  It does however, share
a common line with the hall sensor.

I'm beginning to see some really strange code in the O2 sensor handling
in the MAC11.  It checks for the O2 sensor input voltage being over
4V and handles things differently.  I'm thinking this would be activated
if this input was hard-wired to 5V internally!  Perhaps our computers are
even closer than we think.
