DTC codes / P2Bxx · Hybrid propulsion / P2B4F
P2B4F indicates that the powertrain control module (PCM) has detected a performance problem with the bank 1 camshaft profile actuator B, meaning the actuator is not achieving the commanded camshaft profile change or is stuck in the off position. The PCM monitors the actuator's response through sensor feedback and sets this code when the actual camshaft position or oil flow does not match the desired state within a calibrated time frame.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
