The powertrain control module (PCM) uses that reading along with other sensor parameters to ensure proper fuel delivery at any given time for optimum power and fuel efficiency. Basically, this P00BF diagnostic trouble code (DTC) means that there is a problem with the Mass or Volume Air Flow (MAF) “B” sensor circuit.
Where is the mass air Flow sensor located?
The mass air flow sensor (MAF) is a key component of the electronic fuel injection system in a car. It is located between the air filter and the engine’s intake manifold. In some cars, the intake air temperature (IAT) sensor is built into the mass air flow sensor.
What happens when mass air Flow sensor fails?
A bad MAF sensor can cause your vehicle to experience poor drivability issues such as engine stalling, jerking or hesitation during acceleration. This could happen while speeding up on the highway on-ramp or cruising down a city street. These issues can create dangerous situations causing accidents and injury.
What does the mass air Flow sensor do?
The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly.
What does code P00BD mean?
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 P00BD.
How much does it cost to replace a mass air flow sensor?
MAF Sensor Replacement Cost
The replacement cost of a mass air flow sensor can anywhere from $80 to $380. The cost of the part alone is about $30 to $300 with the lower end of the range for common aftermarket mass air flow sensors while higher quality or more complicated OEM sensors are more expensive.
Is it better to clean or replace a mass air flow sensor?
MAF sensors can become damaged, but more often they just get too dirty to do their job well. In this case, they can be cleaned but if it is a mechanical or electrical failure, they must be replaced. Luckily, it’s a pretty straightforward job.
Will my check engine light come on if my mass air flow sensor is bad?
A check engine light often comes on due to a dirty airflow sensor (MAS). Learn the symptoms of an MAS that needs cleaning, and how to clean it. A mass airflow sensor (MAS) determines the mass of air entering a vehicle’s fuel injection engine, and passes that data to the Engine Control Unit, or ECU.
How do you fix a mass air flow sensor?
Zitat von Youtube: There's an electrical connection that plugs in at the side remove the plugs and loosen the clamps or bolts on the air filter box and lift it up.
How do you check a mass air flow sensor?
Zitat von Youtube: Use clasp if you have to all right next we want to get our test lead and start testing these pins on the harness side the harness side being the side that's not coming from your MAF sensor.
How long does it take to replace a mass air flow sensor?
Less than one hour. Disconnect the negative battery terminal. Unplug the electrical connector on the mass air flow sensor. Use a flathead screwdriver to unfasten the air intake hose clamp at the throttle body.
