About P002C

P002C 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 P002C is stored, the module has detected a signal or supply voltage higher 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 P002C 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 P002C fault code is set when the Engine Control Module (ECM) detects a high voltage condition in the control circuit for the exhaust camshaft profile (variable valve timing system) on Bank 1, Camshaft B. This high voltage condition typically suggests a short to power in the circuit. The variable valve timing (VVT) system is critical for adjusting the exhaust camshaft timing to optimise engine performance and efficiency. A high voltage in the VVT circuit can result in issues with the ECM's ability to correctly manage the exhaust camshaft's timing.
