Q: What does code P2ADE mean?

Reductant Tank Temperature Sensor B Circuit. P2ADE indicates that the powertrain control module has detected an abnormal signal from the reductant tank temperature sensor B circuit, which monitors the temperature of the diesel exhaust fluid tank. The computer compares the sensor voltage to expected values and flags the circuit when the signal falls outside the normal operating range for a calibrated period.
