Q: What does code P2BDC mean?

Motor Electronics Coolant Temperature Sensor C Circuit. P2BDC indicates that the motor electronics coolant temperature sensor C circuit has reported a voltage or signal outside the range the control module expects, which prevents accurate coolant temperature data from being used for fuel and thermal management. The computer detects this when the sensor signal stays too high, too low, or inconsistent with other temperature inputs during key-on or engine operation.
