Codes C1404, C1445 and C1452

We have a 2016 4Runner SR5 Premium 4x4. I had some dash lights come on last week as I was driving along. I did a scan and the following codes showed:
1. C1404
2. C1445
3. C1452

The Dash lights that came on were as follows:
1. ABS
2. Brake (red)
3. Skid Control
4. 4LO (flashing)
5. Center Lock (flashing)

I tried disconnecting the battery and reconnecting, nothing changed.

C1404 looks like the Rear Left Side Speed Sensor
C1445 is "vehicle driven with Steering Angel Sensor Not Initiated
C1452 is Accumulator Low Pressure

The 4Runner doesn't have the simple speed sensor as a separate part, you need to get the sensor and wire harness, about $205 from Larry H. Miller Parts online with discount.
Any thoughts? Does it appear to be just the speed sensor? Rear brakes were done about two months ago by a local shop (daughter had the 4runner at college). Changed out rear rotors and pads.

Thanks Phil

Some folks with similar symptoms on past threads found broken or damaged ABS wires from brake work, off-roading, accidents or other issues. I would check those.

I did a visual on the wiring, it all looked good. I may just change out the sensor/wiring and see if that fixes the issue.

So I pulled the ABS sensor on the left rear axle. There were metal shavings on it and the sensor was damaged. Grinding noise from the axle. Sounds like the axle bearing may be shot. Is it easier to just swap out a replacement axle or to replace the bearings and seal? Thanks
