P006C - MAP – Turbocharger/Supercharger Inlet Pressure Correlation
A Manifold Absolute Pressure Sensor (MAP) is used to measure pressure in the intake manifold. A Turbocharger Inlet Pressure sensor measures the pressure in the air intake system prior to the Turbocharger.
Fault Code Explained
When the vehicle is not running with the ignition on, the values from both these sensors should be the same.The ECM has detected that the values provided from the sensors are different under conditions when they should be the same or are providing conflicting information on the current engine running conditions.
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
