What does code P2B56 mean?

Q: What does code P2B56 mean?

B Camshaft Profile Actuator B Control Stuck On Bank 2. P2B56 indicates that the powertrain control module (PCM) has detected a fault where the bank 2 camshaft profile actuator B control circuit is stuck in the on state, meaning the solenoid is being commanded off but the circuit remains energized or the actuator itself is mechanically stuck in the high-lift position. The PCM monitors the actuator control circuit and compares commanded state to actual feedback; when the circuit voltage or current indicates continuous activation, it sets this code.
