About P0011

P0011 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 P0011 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour; 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 P0011 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 P0011 indicates that the Engine Control Module (ECM) has detected that the intake camshaft position on Bank 1 is more advanced than the commanded target, or that the variable valve timing (VVT) system response is outside the expected performance window. The VVT system uses oil pressure routed through an ECM controlled solenoid to rotate the camshaft phaser and advance or retard cam timing in response to engine load and speed. This code sets when the camshaft position sensor reports an actual timing position that does not match the commanded value for longer than the calibrated threshold, u...
