P0ABD: Hybrid/EV Battery Pack Voltage Sense A Circuit High
What to do
As P0ABC — an electrical fault in the measurement, and the cheap half of the circuit is the reachable half.
What this code means
The pack voltage sense circuit reads at the top of its range — the mirror of P0ABC, with the module possibly restricting charging against an overvoltage that is not there. Sense wiring first, per P0ABA.

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.
