P00BF Lincoln Code - Mass Airflow 'B' Circuit Range/Performance Air Flow Too High

Quick Answer

The Mass Airflow (MAF) Sensor uses a hot wire sensing element to measure the amount of air entering the engine. Common causes include Faulty Mass Airflow (MAF) 'B' Sensor, Mass Airflow 'B' Sensor harness is open or shorted, Mass Airflow 'B' Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

What it means: P00BF Lincoln indicates Mass Airflow 'B' Circuit Range/Performance Air Flow Too High.
Common causes: Common causes include Faulty Mass Airflow (MAF) 'B' Sensor, Mass Airflow 'B' Sensor harness is open or shorted, Mass Airflow 'B' Sensor circuit poor electrical connection.

Code P00BF Lincoln Description

The Mass Airflow (MAF) Sensor uses a hot wire sensing element to measure the amount of air entering the engine. The air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above the ambient temperature as measured by a constant cold wire. The current required to maintain the temperature of the hot wire is proportional to the mass airflow. The MAF Sensor then outputs a signal to the Powertrain Control Module (PCM) proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air to fuel ratio. The MAF sensor is located near the air cleaner assembly. Most MAF sensors have an integrated Intake Air Temperature (IAT) sensor. This Diagnostic Trouble Code (DTC) will be set when the Mass Airflow 'A' Sensor (MAF11) value is within the expected range for the current operating conditions, and the Mass Airflow 'B' Sensor (MAF21) value is greater than the MAF11 value.
