P34BEB Camshaft Position Actuator Position Sensor A Circuit Low Bank 1

P34BE means the engine computer has detected a low-voltage signal on the 'A' circuit of the bank 1 B camshaft position actuator position sensor, which is the feedback sensor inside the variable camshaft timing actuator. The computer expects a voltage within a specific range as the actuator moves, and a sustained reading below that range triggers this code.
