Vehicle Trouble Code P00BF Diagnostic Guide

Fault code P00BF, applicable to all vehicle manufacturers, indicates “Mass or Volume Air Flow ‘B’ Circuit Range/Performance – Air Flow Too High” . This generic powertrain code signifies that the Powertrain Control Module (PCM) has detected that the signal from the Mass Air Flow (MAF) sensor’s “B” circuit is outside the expected range, specifically indicating that the measured airflow is higher than the calculated value .
