The P006E: Turbocharger/Supercharger Boost Control ‘A’ Supply Voltage Low refers to a problem with the supply voltage to the turbocharger or supercharger boost control circuit. This issue can be caused by a faulty boost control solenoid, low voltage supply, wiring or connection issues, or a failure in the Powertrain Control Module (PCM). In simple terms, when this code appears, it indicates that the system responsible for managing the boost pressure in your engine may not be receiving adequate voltage, which can affect engine performance.
