P0A4A: Drive Motor B Position Sensor Circuit Overspeed
What to do
Flatbed only for towing — a rear-motor hybrid towed on its rear wheels spins this motor uncontrolled. If a tow, test or wheelspin episode precedes the code, tell the workshop; it changes the whole diagnosis.
What this code means
The position sensor reported the second motor spinning beyond its limit.
P0A44 carries this family's full argument — the electrical impostor versus the real event — and the real events skew rear-axle here: towing with the rear wheels down on a rear-motor car, prolonged wheelspin, and brake-roller tests that spin one axle. The same flatbed rule applies, and the same free diagnostic: an overspeed code dated to a known event is a record, not a fault.

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.
