What does code P2AD7 mean?

Q: What does code P2AD7 mean?

Reductant Pump Motor Position Sensor Range/Performance. P2AD7 indicates that the reductant pump motor position sensor, which reports the rotational position of the diesel exhaust fluid (DEF) pump motor, is sending a signal outside the expected range or is not performing reliably. The engine control module (ECM) compares this signal against expected values and sets the code when the voltage or position reading falls outside calibrated limits for a set time.
