P2BE3: Hybrid/EV Battery Coolant Level Sensor Circuit High
Standardized SAE J2012 code · P2Bxx codes
What does P2BE3 mean?
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.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Symptoms
- EV/hybrid system warning light on
- Reduced power output or limp mode
- Charging may fail or be slowed
- Reduced electric range
Common causes
- High Signal wire shorted to B+
- Medium Open level sensor
- Low Connector pins corroded - high contact resistance
