P0247 — Turbocharger Wastegate Solenoid B Malfunction

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0247

P0247 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.

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 P0247 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 P0247 fault code is set when the Engine Control Module (ECM) detects a malfunction in the Turbocharger Wastegate Solenoid B. This solenoid is part of the system that controls the wastegate valve in a turbocharger system, typically in vehicles equipped with multiple turbochargers or a twin-turbo setup. The wastegate solenoid ensures that the boost pressure generated by the turbocharger does not exceed the engine's safe operational limits. A malfunction in the wastegate solenoid B can lead to issues with turbocharger performance, potentially causing either insufficient or excessive boost pre...
