Your distribution block is located under the hood, behind drivers headlight and in front of the battery.
There's a plastic release tab, which will allow you to open the lid to it. On the inside of the lid will be a diagram showing which fuses are used for what. Check all the ABS related fuses.
In the interior fuse panel, which is on the drivers side of the dash to the left of the steering wheel (with the door open) you'll see an access panel. Remove it by grabbing ahold of the tab on the bottom of the cover and pulling out. I believe there is only one ABS fuse in here for the ABS controller. IIRC it's fuse #38 (but if you have an owners manual, reference the maintaining your vehicle section for clarification).
Check all these fuses.
As for testing the ABS sensor itself, I'd check the wiring and connectors mentioned previously before undoing the connectors and testing them.
To test them, you can remove the connectors which are located in the engine bay and use a DVOM to test them.
Find the connectors by following the ABS wire through the wheelwell and into the engine bay. The drivers side is hidden decently well, but the passengers side is fairly visible once you know where it is.
Both should be pushed down onto metal studs and will need to be pulled off them to be able to undo the connectors for testing. But remember to place them back onto the studs after testing as the wires will hang too close to the engine otherwise, get brittle over time from the heat and crack/warp/melt/corrode.
I'd inspect the fuse and wiring before jumping to a bad sensor though, as a bad sensor would've set off your ABS light before having to brake at all.
My best guess is that the ABS wires werent properly connected to the brake hoses and wheel well liner and were allowed to dangle or stretch in an area they shouldn't have been hanging. Or perhaps they didn't reach the hub properly after being lifted.
If you don't see any obvious culprits, check back and hopefully we can add some more input to point you in the right direction.
