Q: What does code P2B94 mean?

Wastegate Position Sensor B Exceeded Learning Limit. P2B94 indicates that the powertrain control module (PCM) has detected the wastegate position sensor B signal has moved beyond the learned operating range during a self-calibration or position-learn routine. The PCM expects the sensor to report a specific sweep of positions as the wastegate actuator moves from fully closed to fully open, and this code sets when the sensor voltage or position reading falls outside the stored min/max limits.
