P006A INFINITI – Manifold Absolute Pressure – Mass Air Flow Correlation

P006A INFINITI Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P006A INFINITI Possible Causes

Faulty Mass Air Flow (MAF) or Manifold Absolute Pressure (MAP) Sensor,MAF or MAP sensor harness is open or shorted,MAF or MAP sensor circuit poor electrical connection

P006A INFINITI Description

The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. The mass air flow sensor controls the temperature of the hot wire to a certain amount. The heat generated by the hot wire is reduced as the intake air flows around it. The greater air flow, the greater the heat loss. Therefore, the electric current supplied to hot wire is changed to maintain the temperature of the hot wire as air flow increases. The Engine Control Module (ECM) detects the air flow by means of this current change.
