P00BF

DTC P00BF, sometimes indicated as P00BF00 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing mass or volume air flow "b" circuit range/performance - air flow too high.

The DTC P00BF: Mass or Volume Air Flow "B" Circuit Range/Performance - Air Flow Too High code means that the air flow is too high. There are several possible causes for this code, including a dirty air filter, a defective mass air flow (MAF) sensor, or a vacuum leak.
If the code is caused by a dirty air filter, the solution is to clean or replace the air filter. If the code is caused by a defective MAF sensor, the solution is to replace the sensor. If the code is caused by a vacuum leak, the solution is to fix the leak.
