Hybrid/EV Battery Coolant Level Sensor Circuit/Open

Where it lives

For P2BE0, the sensor sits on the circuit this code reports. The description of P2BE0 reports the sensor as open.

Check these first

• An open in the hybrid battery coolant level sensor circuit
• A coolant level sensor float stuck and not switching
• Low coolant causing the sensor to read open
• Corrosion at the coolant level sensor connector

What to do next

1. Read hybrid battery coolant level status on a scan tool
2. Check the coolant level in the battery coolant reservoir
3. Test the coolant level sensor circuit for an open
4. Inspect the sensor connector for corrosion
5. Replace the coolant level sensor if the circuit tests good
6. Clear the code and retest
