P002A — Exhaust Camshaft Profile Circuit Open - Bank 1 - Camshaft B
System: Powertrain | Type: Generic (OBD-II Standard) | Make: Generic
P002A 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 P002A 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 P002A 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.
The Engine Control Module (ECM) monitors the electrical integrity of the exhaust camshaft profile control circuit on Bank 1, Camshaft B. Camshaft profile control systems use an electrically actuated solenoid to switch between cam lobe profiles, altering exhaust valve lift or duration to improve cylinder scavenging, emissions, and efficiency across the operating range. P002A is set when the ECM detects an open circuit on the control side of this solenoid, meaning no current flows when the output is commanded on. With the circuit open the profile switch cannot occur, leaving the exhaust cam lock...
