About P0035

P0035 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 P0035 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 P0035 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

DTC P0035 sets when the Engine Control Module detects a high voltage or open condition in the control circuit of the turbocharger or supercharger bypass valve, the valve that vents or recirculates charge pressure so the forced induction system is not overloaded. The ECM operates this valve, or its control solenoid, with a switched or pulse width modulated signal and monitors the circuit voltage on its low side driver. The High code points to the control side sitting higher than expected, typically an open solenoid winding, an open or high resistance in the control or ground wiring, or a short ...
