I don't think what you describe is abnormal (i.e.,  a 45 second 
interval can be about right, AFAIK). A relatively brief duration 
might , in part, be a result of cool ambient (air) temps. BTW, during 
this cool time of the year the afterrun for some cars (e.g., mine) 
may not ever activate-- even after moderately "spirited" driving. 
Fairly consistently, my car has no afterrun fan until the ambient 
temp is above approx. 70 degrees F.

  IMHO, your sensor is probably working OK.  I believe there is a 
separate timing circuit (in the relay?) that determines the duration 
of the fan cycle. In hot weather--and with a very hot turbo-- if/when 
a single fan cycle is not sufficient to cool things down adequately, 
the fan will come on again after a brief interval.
