Air sensor fault
hi. Recently got a disco 4 but now got "reduced performance " on dash.plugged computer in to find out "airflow sensor B low current" changed the sensor and cleared the fault. As soon as the car was started it generated the same fault again. Someone suggested a cracked air manifold but upon inspection its as dry as a bone with no oil deposits just dust/dirt. Anyone got any other ideas. Many thanks.

Thanks for the video gstuart. Thats exactly what we did however as soon as the engine started it threw the same fault up again. Someone said it may have been the manifold but checked that and all was dry. ..
