About P0014

P0014 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 P0014 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 P0014 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 exhaust camshaft position on Bank 1 by comparing the exhaust camshaft position sensor signal against crankshaft position. DTC P0014 is set when the ECM detects that the measured exhaust camshaft angle is more advanced than the commanded position by a calibrated threshold, typically held for a set period to confirm the fault is genuine. Exhaust camshaft phasing is controlled by an Oil Control Valve (OCV) that routes pressurised engine oil into advance or retard chambers of the cam phaser, allowing the ECM to vary valve timing for emissions and performanc...
