Code Definition

P0245 — Turbocharger Wastegate Solenoid A low

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

About P0245

P0245 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 P0245 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 P0245 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 P0245 fault code is set when the Engine Control Module (ECM) detects a lower than expected input signal or voltage in the Turbocharger Wastegate Solenoid A circuit. The wastegate solenoid plays a critical role in the turbocharger system, controlling the wastegate valve that regulates the boost pressure produced by the turbocharger. A low input signal might suggest an electrical issue, such as a short to ground, a malfunctioning solenoid, or problems with the wiring or connectors. This condition can result in the wastegate not functioning properly, potentially leading to insufficient boost ...
