Code result
P0ED1
Hybrid/EV Battery Multiple Sensor Voltage Correlation
High severity
What it means
The BMS detects that multiple HV battery voltage sensor readings disagree beyond calibration. SOC/SOH calculations unreliable.
Is it safe to drive?
No — stop driving
This code can put the vehicle into limp or reduced-power mode. Avoid extended driving and have the vehicle diagnosed promptly.
Most likely causes
Sensor offsets drifted
highOne of the most commonly reported causes for this code — check this first.
Sense wire resistance high
mediumA plausible cause — test and verify before replacing parts.
Pack cell imbalance approaching service threshold
lowLess common, but worth ruling out after the more likely causes.
