What does code P2AB7 mean?

Q: What does code P2AB7 mean?

Wastegate Position Sensor A Circuit. P2AB7 indicates that the powertrain control module has detected an implausible or out-of-range signal from the wastegate position sensor on circuit A, which is the primary feedback channel for the turbocharger's wastegate actuator. The computer compares this sensor's voltage against expected values for the commanded boost level and sets the code when the correlation falls outside calibrated limits.
