Several Codes on my 2004 V70

[Dladd]

I have a 2004 V70 non turbo. The other day while driving, it started running rough, and lost acceleration. I got it to the parts store, and they read the codes for me. The codes are as follows;

1) P2227 Barometric Pressure Sensor A Circuit Range/Performance
2) P0305 Cylinder 5 Misfire
3) P0171 System Too Lean Bank 1
4) P0106 Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem

Any idea of what would cause these codes, all at once. Any advice to help is greatly appreciated!

Clear codes and see what comes back first. Those sensor codes are often spurious.

You just missed me sounding two weeks in Richmond...great town !

First do as Abscate say.

After that, keep in mind the Manifold Absolute Pressure and the Barometric Pressure, which are extensively the same type of sensor, are known to become temperature sensitive and crap out in extremely low temperatures.

P0305 and P0171 could be the results of the ECM miscalculating the fuel due to incorrect information from the Manifold Absolute Pressure and the Barometric Pressure.

Thanks for the reply. I will clear the codes, and go from there. Thanks again
