Default 2 fault codes, where are sensors? G71 and G31.

Hi all,

My saga continues. Got car back after finding the waste jammed open by a lost nut from last fix. Now the car is tossing 2 fault codes.
1. Manifold / Barometric Pressure sensor G71/F96
2. Manifold Pressure / Boost sensor G31.

I believe that G31 is on top of the rubber boot between the pipes and the throttle body.

Where is the G71 sensor?

Thanks for any help.

OK, both code point to the boost pressure sensor in boot at the throttle body.I replaced the sensor and things are back to normal again. Oh, I picked up a used sensor and it works fine. I saved 200.00 over retail.
