P006A - MAP – Mass or Volume Air Flow Correlation
A Manifold Absolute Pressure Sensor (MAP) is used to measure pressure in the intake manifold. A Mass Air Flow Sensor (MAF) is used to measure the mass of air entering the engine. The ECM uses the values from these sensors to measure engine load.
Fault Code Explained
The ECM has detected conflicting information from these sensors but is unable to determine which sensor value is incorrect.
If possible use a diagnostic computer to read live data to establish which of the sensors is providing incorrect values.Carry out wiring and sensor output tests on the faulty circuit
