What does code P2ADB mean?

Q: What does code P2ADB mean?

Reductant Tank Temperature Sensor B Circuit Low. P2ADB means the reductant tank temperature sensor B circuit is reporting a voltage below the expected range, so the engine control module sees an implausibly cold or shorted signal. The computer has detected a low-voltage condition on that sensor circuit, which can prevent the diesel exhaust fluid system from dosing correctly.
