I = had hypothesized=20 that Rusty had used the OAT bias supply on P2-21 for the other sensor = +5 =20 (do not do this).  The OAT sensor red lead  should go to one = of the +5=20 volt pins and should be an OK source for the other air temp = sensor.  This=20 should not have changed the OAT reading.  Don't know why it=20 did.
