P2BE3 Hybrid/EV Battery Coolant Level Sensor Circuit High
The hybrid control module detects a circuit high fault on the high-voltage battery coolant level sensor. Coolant loss in the battery loop cannot be detected reliably.
Is it safe to drive with P2BE3?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
