What does code P2ADC mean?

Q: What does code P2ADC mean?

Reductant Tank Temperature Sensor B Circuit High. P2ADC indicates that the powertrain control module has detected an abnormally high voltage on the signal circuit of the reductant tank temperature sensor B, which is used to monitor the temperature of the diesel exhaust fluid tank. The high voltage reading typically means the circuit is open, shorted to voltage, or the sensor's internal resistance has risen beyond the expected range for the current temperature.
