Q: What does code P2B37 mean?

A Camshaft Profile Actuator B Control Circuit Low Bank 2. P2B37 indicates that the powertrain control module (PCM) has detected a low-voltage condition on the control circuit for the bank 2 camshaft profile actuator, which is the solenoid or motor that changes valve lift or timing profile. The PCM commands the actuator to a specific position and monitors the circuit; when the feedback voltage stays below the expected threshold for a calibrated time, it sets this code and may disable the profile-shifting function.
