P0B62Hybrid/EV Battery Voltage Sense H Circuit Intermittent/Erratic

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
P0B62 describes a channel H signal that jumps or cuts out for moments rather than failing permanently. No manufacturer documents this code publicly. It is worth noting that Ford's 2023 Mach-E and E-Transit bulletin attributes an intermittent flexible printed circuit fault to the open-circuit code P0B5E, not to P0B62, and GM's published tables contain no erratic monitor for channel H at all. The code is therefore defined by SAE J2012 but appears to remain unused in practice. CARB demands that battery voltage sensors of the energy storage system be checked like every other input. If it ever appears, logging channel H next to channels G and I while moving the harness is the sensible first step.
What you may notice
  • Warning appears occasionally and clears after a restart
  • Short interruptions of electric drive
Likely causes
  • LikelyIntermittent contact at the channel H connector or flexible circuit
  • PossibleCracked solder joint on the monitoring board
  • RareInverter noise coupling into the sense line
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
