P03EBA Camshaft Profile Actuator Position Sensor C Exceeded Learning Limit

P03EB indicates that the powertrain control module (PCM) has detected that the camshaft profile actuator position sensor C has exceeded its learned operating range during the actuator's self-learning routine. The computer tried to calibrate the variable valve timing system and found that the sensor's signal fell outside the expected limits, meaning the actuator or its sensor is not responding as designed.
