Code Definition

P0246 — Turbocharger Wastegate Solenoid A High

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

About P0246

P0246 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 P0246 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 P0246 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 P0246 fault code is set when the Engine Control Module (ECM) detects a higher than expected input signal or voltage in the Turbocharger Wastegate Solenoid A circuit. This solenoid is responsible for controlling the wastegate in a turbocharger system, which regulates the boost pressure to prevent it from exceeding the engine's maximum safe limits. A high input signal may indicate an electrical issue such as a short to power in the solenoid circuit, a malfunctioning solenoid, or issues with the wiring or connectors. Such a condition can lead to improper wastegate operation, potentially causi...
