Default Baro reading and P0101 MAF DTC

Hi All,
My 2012 JGC CRD keeps throwing a DTC P0101 Mass Airflow out of range, which leads to other codes to do with EGR and Turbo underboost a few minutes later. I have changed the MAF sensor with no difference. My cheap OBD scanner also does data stream readings, 29 pages. One category is Baro i.e. barometric pressure in kPa. ~ normal sea level, normal day this should be about 100.0kPa engine on or off. My reading is Baro zero although another category is MAP Manifold Air Pressure which is showing 101.0kPa. The MAP sensor is supposed to have a barometric sensor cell. I also have a Pajero diesel and it has Baro reading 100.0kPa and also has a MAP reading 101.0kPa engine not running and 98.0kPa when running. See photos.
Can anyone with the same JGC CRD and a scanner let me know if they have a Baro reading at all?

Many thanks, Adrian.
