Hybrid/EV Battery Pack Current Sensor C Circuit Range/Performance
The hybrid control module detects a circuit range/performance fault on the high-voltage battery pack current sensor C. Pack-level current measurement is impaired.
Affected components
- Hybrid battery current sensor c
- Wiring harness
- Bms
Common causes
- High likelihood: Sensor zero drifted
- Medium likelihood: Magnetic offset from nearby ferrous parts
- Low likelihood: Sensor element aged beyond calibration window
Possible symptoms
- EV/hybrid system warning light on
- Reduced power output or limp mode
- Charging may fail or be slowed
- Reduced electric range
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
