P0ED1 Hybrid/EV Battery Multiple Sensor Voltage Correlation
The BMS detects that multiple HV battery voltage sensor readings disagree beyond calibration. SOC/SOH calculations unreliable.
Is it safe to drive with P0ED1?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelySensor offsets drifted
- PossibleSense wire resistance high
- Less likelyPack cell imbalance approaching service threshold
Symptoms
