What does code P2B93 mean?

Q: What does code P2B93 mean?

Wastegate Position Sensor A Exceeded Learning Limit. P2B93 means the powertrain control module has learned that the wastegate position sensor's feedback voltage no longer falls within the expected range during its self-calibration routine, so the turbocharger's boost control is not being verified correctly. The computer detected that the sensor's learned position offset has exceeded the allowable limit, which typically points to a mechanical binding, a sensor fault, or a wiring problem in the wastegate actuator circuit.
