manifold pressure boost sensor(G31)signal too low
P0237
manifold barometric sensor(G71)/(F96)implausible signal.P0106
As soon as I clear them they come right back instantly. Without even turning on the car, it has to be something electrical, just got a new MAF from the dealer could it have gone bad already?

Group115:charge pressur control(boost)
Engine speed-760/min
Engine Load-20.3%
spec.Boost-990.0 mbar
actual Boost-30.0 mbar
Group113:
idle speed-760/min
Engine load-20.3%
throttle drive-2.0%
Air pressure-995.0 mbar
Do those numbers seem normal? this is at idle.All of my connections are ok.

manifold pressure boost sensor(G31) is really too low. It should be around 1000 mbar.
So, you should check the connector and the wiring and the sensor(G31) itself. I think the best way is to swap the sensor(G31) with the other car.
