Are you referring to the Manifold Pressure/Vacuum Sensor? If so, it is located on the top rear section of the intake manifold.

That depends on the year/model.

 

Just a FWIW - if it's a turbo (your S obviously isn't) - that's not it.

 

On the 958 turbo V8 - it's located ahead of the intake throttle body in the Y tube leading to the intake.  It's the device in the red box in the attached photo. It's lots of $$$ from Porsche, but if you search on the Bosch PN - you'll find it was used for everything from Chevy turbo engines to Rolls Royce turbo engines.. and the price can be as little as $18 with just a bit of searching (and your nearby NAPA store if you're in the US probably has one in stock.)  If you're going to replace the one in the parts diagram - might be worth Googling the Bosch PN that is likely on it. It might be much cheaper than you might think.
