Default Pressure sensor

My car is a 1999 Legacy Outback with a 2.5 engine and a 5 speed manual transmission.
I have been having some rough idle issues and pinging. I am trying to diagnose these issues. However, I need some clarification. Upon reviewing the Haynes manual in chapter 6-10 "Pressure Sensor" step 23 I read that the pressure sensor is only used on automatic transmissions and turbo models. My car has one! and according to the book I am not supposed to.

Can someone please help clarify if my manual transmission and non-turbo car is supposed to have this part?

Also on my coil pack (Diamond brand) I am measuring about 12k ohms on the secondary coil pack and the Haynes manual list the resistance to be between 17.9 and 24.5k Ohms. Is the Haynes manual correct on this spec?

thanks in advance
-Rob

Pressure sensor (MAP sensor) is used on all models with and without MAF's; with and without turbo's.

Not sure on the coil ohms.

Thanks for the reply. I am still wondering why the Haynes manual says that it is not used on the manual transmission.
