Q: What does code P2ADA mean?

Reductant Tank Temperature Sensor B Range/Performance. P2ADA indicates that the powertrain control module has detected an out-of-range or performance fault in the reductant tank temperature sensor B circuit, which monitors the diesel exhaust fluid tank temperature. The computer compares the sensor signal against expected values and flags the code when the reading is implausible, stuck, or outside the valid range for the current operating conditions.
