About P001F

P001F 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 P001F is stored, the module has detected a signal or supply voltage higher than the expected operating range; and a bank-specific fault, meaning it applies only to one cylinder bank of a multi-bank engine.

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 P001F 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 Engine Control Module (ECM) monitors the voltage on the control circuit of the intake camshaft profile solenoid for Bank 2, Camshaft A. Camshaft profile control systems use an electrically actuated solenoid to switch between cam lobe profiles, altering valve lift or duration to match engine load and speed. P001F sets when the ECM sees the voltage on this control line held higher than expected, typically indicating a short to battery voltage in the control harness or an open in the low side return that leaves the line pulled up by the internal sensing circuit. With the line stuck high the E...
