About P002E

P002E 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 P002E 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 P002E 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 P002E fault code is set when the Engine Control Module (ECM) detects a low voltage condition in the control circuit for the exhaust camshaft profile (variable valve timing system) on Bank 2, Camshaft B. This low voltage condition often indicates a short to ground within the circuit. The variable valve timing system is crucial for optimising engine performance and efficiency by adjusting the timing of the exhaust camshaft. A low voltage in the circuit can impair the ECM's ability to control the camshaft timing accurately.
