P2BE7Hybrid/EV Battery Pack Current Sensor C High

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
With P2BE7 the signal of current sensor C sits above its usable range, which after conversion would be an impossibly large current. As with P2BE6, the official wording drops the word circuit. No manufacturer documents P2BE7 publicly. GM's coarse-channel check for sensor A (P0AC2) shows typical numbers: above 303 A (ADC count over 4013) during 1.6 s out of every 2 s, Type A, MIL on the first trip. An open sensor ground, a signal touching the supply or an internal sensor fault are common causes. Where three current devices sit on one busbar, as in a Continental patent, the remaining two can still be compared, which helps the controller decide which one is wrong. CARB requires such range checks. Low is P2BE6.
What you may notice
  • MIL and hybrid or EV warning on
  • Battery power limited
Likely causes
  • LikelyOpen sensor ground
  • PossibleSignal wire shorted to the 5 V supply or 12 V
  • PossibleCurrent sensor C defective
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
