ABS light on after front wheel bearing replacement

This past weekend I replaced the driver's side front wheel bearings and hub on my 09 4x4 Tacoma. After getting everything back together I started up the truck, pumped the brake pedal a few times to close up the calipers and took it for a drive. Upon braking an intermittent thumping sound occurred at the driver's side front wheel and reoccurred every time I would brake. I came to the realization that it was the ABS system and knowing the quick trick of disconnecting the wheel sensor under the hood I disconnected and continued driving. The thumping and irregular braking stopped and everything felt smooth. After plugging the sensor back together the ABS doesn't kick in while braking but the ABS and skid control lights on my dash have stayed on (they came on when I disconnected the sensor). I've tried disconnecting and reconnecting my battery and the lights stay on. Any ideas on whether the sensor at the wheel needs replaced or could it have something to do with the new wheel bearings and/or hub? Thanks in advance for your advice.

 

Yes, I pulled the sensor out, wiped it clean with a cloth rag, reinstalled it and the light has stayed on.

 

Same problem..... Bump!

 

ig you puled the sensor out and cleaned it, i assume you kept the original pickup. is there a chance you pulled a little too hard on the wires? i have seen that a few times in my life. to check the pickup and the wires, unplug the sensor, lift and remove the wheel, and use a volt meter set to AC, put the leads on the sensor, rotate and look for AC voltage. if none, the wire is broken, or the pickup is bad.

 

Here's something. It's for a 2009 toyota corolla, but he states having to reset the abs system after replacing an axle. Again, this is for a corolla, so the reset connections could very well be different. But a reset may be what's needed.
