What does code P2ABC mean?

Q: What does code P2ABC mean?

Wastegate Position Sensor B Circuit High. P2ABC indicates that the powertrain control module has detected an abnormally high voltage on the signal circuit of the wastegate position sensor B, which is used on turbocharged engines to monitor the actual position of the wastegate valve. The sensor typically receives a 5-volt reference and returns a voltage that rises as the wastegate opens; a high reading means the signal is near or at the reference voltage, suggesting an open circuit, a short to voltage, or a sensor that has failed internally.
