P0EB6 Hybrid/EV Battery Pack Voltage Sense Circuit Performance
BMS detects rationality fault in pack voltage sense channel, with sum of cell voltages disagreeing from total pack voltage measurement beyond tolerance.
Is it safe to drive with P0EB6?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelyBMS sense channel drift
- Less likelyPack cell imbalance approaching service threshold
- Less likelyGround point with elevated resistance
Symptoms
- EV/hybrid system warning light on
- Reduced power output or limp mode
- Charging may fail or be slowed
- Reduced electric range
