Greetings! Code 003A help please

Just got a 2010 Mazda 6. 110k, touring package (I think...fogs, tilt, power everything...) with a 6 speed manual. Super nice car and I was thrilled to get it for $3,500. Anyway, had a brake-warning light so I plugged the car in and "C003A" was there. Passenger rear ABS sensor. Replaced the sensor with a new Mazda part. Cleared the code. Took the car out ad it popped the code as soon as I got above 5 mph - which is when the sensor is active.

Checked the power at the connector and its a shade over 10.4 volts which is spec. No shorts open or to ground. Can't see live data on my scanner, but I suspect its something inside the hub that's throwing it off.

Am I on the right track, Mazda folks?

Thanks

Update - because it'll help future searchers...

Tested the entire harness and it checked out. Jacked back of car up, turned the key to KOEO and probed into a known good sensor. Spun the wheel and watched the volts climb on my meter. Tapped into suspected bad (new) sensor and it flatlined when the wheel spun. Testing now confirmed a bad Mazda / OEM replacement sensor. Dealer said I have to bring the car in and have their service department test the sensor in the car before they warranty the part. Not sure the day without a car is worth the $79 for another sensor.

Bonus - the bolt that attaches the sensor to the hub has a brass receiver in the hub. The threads strip out if you look at them wrong. Don't ask me how I know.

That is great! At least, you don't have to turn the car upside down to look for the fault.
