P2BE0Hybrid/EV Battery Coolant Level Sensor Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2BE0 concerns the wiring of the level sensor in the coolant reservoir of the high-voltage battery loop: its signal is missing or the line is broken. Stellantis documents the code as P2BE0-00 on the 2021-22 Chrysler Pacifica Hybrid, where the cluster asks for hybrid system service; Tech Tip 9004552 tells dealers to photograph the level in the battery coolant bottle before swapping sensor or bottle, so the real level is part of the diagnosis. GM watches the same part on the Chevrolet Volt under its own codes P1FFB to P1FFF; there an open line drives the signal above 4.0 V, 40 of 50 samples at 100 ms, Type A. Plausibility, low and high faults are P2BE1 to P2BE3. Expect a hybrid warning and possibly blocked charging.
- What you may notice
- Service hybrid system message on the cluster
- MIL on
- Plug-in charging disabled on some models
- Likely causes
- LikelyBattery coolant level actually low (leak or after service), bulletin asks to check first
- PossibleLevel sensor defective, e.g. internal solder joints (GM Volt)
- PossibleOpen signal wire or loose connector at the reservoir
- RareInternal break in the sensor jumper harness
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
