Z4 Roadster (E85) Fault Code: 2D2A

I got Z4 2007 3.0i. I got my ses code few weeks ago. I went to auto zone and got the fault code P1124. Someone told me it means Throttle Position Sensor out of self test range. I went to a body shop and they got the manufacture code: 2D2A Differential-pressure sensor, intake manifold: adaptation.
I've been driving with lights on for a long time and never feel anything while driving. The lights always goes on, goes off, and goes on again.
Anybody can help with it? Thanks a lot!
