About P001E

P001E 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 P001E is stored, the module has detected a signal or supply voltage lower 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 P001E 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. P001E is set when the ECM sees the voltage on this control line held below its expected off state threshold, typically indicating a short to ground between the solenoid and the ECM driver, or an internal short within the solenoid itself. With the control line stuck low the ECM cannot pro...
