What does code P2A4D mean?

Q: What does code P2A4D mean?

Alternative Fuel Temperature Sensor Circuit Low. P2A4D indicates that the powertrain control module has detected a voltage signal from the alternative fuel temperature sensor that is lower than the expected range for the current operating conditions. This low signal typically means the sensor circuit is shorted to ground or the sensor element has failed in a way that reduces its resistance.
