What does code P1534 mean?

P1534 · BMWB Camshaft Position Actuator Control Circuit Signal High Bank 2

This code means the engine computer (DME) has detected an abnormally high voltage signal on the control circuit for the bank 2 B camshaft position actuator, which is the variable valve timing solenoid on the exhaust camshaft of the cylinder bank that does not contain cylinder 1. The computer expects a specific duty-cycle-controlled voltage on the actuator's ground-side control wire, and a reading above the expected threshold for a calibrated time sets this fault.
