About P006E

P006E is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P006E is stored, the module has detected a signal or supply voltage lower than the expected operating range.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P006E is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P006E fault code is set when the Engine Control Module (ECM) detects a lower than expected voltage in the supply circuit for the 'A' boost control solenoid of the turbocharger or supercharger system. This solenoid is part of the system that controls the amount of boost (pressurised air) supplied to the engine from the turbocharger or supercharger. The solenoid typically operates via an electronic signal from the ECM, which regulates the boost pressure based on various engine parameters. A low voltage condition in this circuit can impair the ECM's ability to effectively control the turbocha...
