About P002D

P002D 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 P002D is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit; 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 P002D 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 P002D fault code is set when the Engine Control Module (ECM) detects an open circuit condition in the control circuit for the exhaust camshaft profile (variable valve timing system) on Bank 2, Camshaft B. This indicates a break in the electrical continuity of the circuit, which is essential for the functioning of the variable valve timing mechanism. An open circuit can hinder the ECM's ability to accurately control the timing of the exhaust camshaft, potentially impacting engine performance, emissions, and fuel efficiency.
