What does code P2BDE mean?

Q: What does code P2BDE mean?

Motor Electronics Coolant Temperature Sensor C Circuit Low. P2BDE indicates that the motor electronics coolant temperature sensor C circuit is reporting a low signal condition, meaning the engine control module sees a voltage or resistance value below the expected range for the current operating conditions. The computer has detected that the sensor's output is lower than it should be, which can distort the coolant temperature reading used for fuel delivery, fan control, and emissions strategies.
