P0A58: Drive Motor B Current Sensor Circuit High
What to do
An abrupt loss of this motor's drive is likely protection against a false reading — pass that on with the code.
What this code means
Motor B's current sensor circuit reads at the top of its range.
The P0A54 caution applies: a maxed reading can trigger a hard shutdown of this motor as a false overcurrent. On rear-motor cars that presents as all-wheel drive vanishing abruptly.
Likely causes

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.
