Hybrid/EV Battery Pack Current Sensor B Circuit Range/Performance
The ECM detects a circuit range/performance fault on the hybrid/ev battery pack current sensor b circuit. Reading cannot be used reliably for control.
Affected components
- Hv battery pack current sensor b
- Wiring harness
- Bms
Common causes
- High likelihood: Sensor characteristic drifted
- Medium likelihood: Sensor mounting displaced
- 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
