What are the common causes of P006C?

A failing or dirty MAP sensor. A failing turbocharger or supercharger inlet pressure sensor. A boost or intake leak. A clogged air filter or inlet duct. A wastegate or boost control solenoid fault.

Compare MAP and turbo inlet pressure readings on a scan tool. Inspect the intake and charge pipes for boost leaks. Check the air filter and inlet duct for blockage. Test the boost control solenoid and wastegate operation. Replace the MAP or inlet pressure sensor that is faulty. Clear the code and retest.
