Default where is the map sensor located on the 95 bonneville?

i was wondering where is the map sensor located on a 95 bonneville? according to the chilton book the map sensor sits on top of the pcv valve case, but i looked at my engine and i don't see it sitting on top, its not there, where else would the map sensor be?

Take the plastic cover off the top of the engine (the one that reads Series II 3800).
Standing in front of the car you will see a sensor at the passenger side of the upper intake manifolds with clips on both the left and right side. This is the MAP sensor.
Here'* a pic of the same engine with MAP sensor visible directly in front of the alternator (yellow/white clip).

yes i see it in the picture but i don't have the map sensor where it is supposed to be, all i see is just the cover nut for the PCV valve but no MAP sensor on top of it, do all the 3.8 series 2 come with MAP sensors? its weird cause mine isn't there, possibly my didn;t come with one?
