P0A47: Drive Motor B Position Sensor Circuit Low
What to do
Expect this motor's contribution — often the all-wheel drive — to be absent while stored. Wiring first.
What this code means
Motor B's position circuit reads low — a short to ground or an open excitation line.
Circuit fault, not angle fault: continuity and shorts on the harness, resolver last. The underfloor run is the exposed section on rear-motor installations.
Likely causes
Start here
- Wiring shorted to ground · moderate
- Corroded or loose connector · easy
Less common

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.
