P0A41: Drive Motor A Position Sensor Circuit Low
What to do
Electric drive may be unavailable while this is stored — the car is not being dramatic, it genuinely cannot time the motor without this signal. Wiring diagnosis first.
What this code means
The drive motor position circuit reads low — a signal line shorted to ground or an excitation winding gone open.
An extreme electrical reading identifies the fault as circuit rather than angle, which at least narrows the work: this is a continuity-and-shorts diagnosis on the harness between transaxle and inverter, with the resolver last on the list for the reasons at P0A3F.

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.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.
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.
