P2BE4: Hybrid/EV Battery Pack Current Sensor C Circuit

Standardized SAE J2012 code · P2Bxx codes

What does P2BE4 mean?

The hybrid control module detects a circuit fault on the high-voltage battery pack current sensor C. Pack-level current measurement is impaired.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

Symptoms

  • EV/hybrid system warning light on
  • Reduced power output or limp mode
  • Charging may fail or be slowed
  • Reduced electric range

Common causes

  • High Current sensor failed
  • Medium Wiring or connector fault
  • Low Pack cell imbalance approaching service threshold

Likelihood is a general estimate across vehicles; your make and model may differ.
