About P003E

P003E 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 P003E is stored, the module has detected 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 P003E 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 intake camshaft profile control system uses an oil pressure driven actuator, commonly a two stage cam profile switching mechanism, to change intake valve lift or duration on Bank 2 Camshaft A. The Engine Control Module (ECM) energises the profile control solenoid, which directs pressurised engine oil to the switching element in the camshaft phaser or switching lifter assembly, then confirms the change using camshaft position sensor feedback. DTC P003E is set when the ECM commands the intake camshaft profile to switch but the feedback indicates the mechanism has remained in the off or base ...
