About P001D

P001D 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 P001D is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit; 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 P001D 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 electrical integrity of the intake camshaft profile control circuit on Bank 2, Camshaft A. Camshaft profile control systems use an electrically actuated solenoid to switch between cam lobe profiles, allowing the engine to alter valve lift or duration for improved performance and efficiency. P001D is set when the ECM detects an open circuit on the control side of this solenoid, meaning no current is flowing when the output is commanded on. With the circuit open the profile switch cannot occur, so the engine remains locked on one cam profile and may e...
