P00BF OBD-II: Mass or Volume Air Flow "B" Circuit Range/Performance - Air
P00BF Severity
Should you fix P00BF yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P00BF?
The Mass Airflow Sensor (MAF) measures the amount of air entering the engine. The engine control module (PCM) uses this information to determine how much fuel to use to keep the engine running properly. When the PCM detects a problem with this sensor or the circuit for the sensor, it will set code P00BF.
