P0B60: Hybrid/EV Battery Voltage Sense H Circuit Low
What to do
As P0B3D — a group reading almost nothing is usually a disconnected or broken measuring wire, because a real cell group does not empty quietly. Worth saying to anyone who quotes a battery for it.
What this code means
Cell group H's sense circuit is reading below its valid range — the opens-and-resistance direction, where a near-zero reading points at a broken measuring wire rather than an empty cell group. Set out at P0B3D; family argument at P0B3B.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
