About P006F

P006F 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 P006F is stored, the module has detected a signal or supply voltage higher 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 P006F 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

Boost control circuit A is the primary switched voltage feed supplying the turbocharger or supercharger boost control solenoid or electric actuator, taken from the main relay, a dedicated boost control relay, or an internal supply driver within the Engine Control Module (ECM). The ECM monitors the voltage present on that feed and expects it to sit at system voltage while energised and to fall to zero once the circuit is commanded off. DTC P006F is set when the ECM measures the circuit A supply voltage above its calibrated upper threshold, which happens either because the vehicle charging syste...
