When I drive the ABS and TCS lights turn on? Code C1233?

The brakes work perfectly until the lights come on, then after they turn on the car pulls to the side. Error being thrown is the front left traction control sensor, so I changed that out, and it didn't go away. I tried cycling the car a few times, and unplugging battery to reset, and didn't work.

What code number is it? The sensor works off of the CV axle so I don't think that could have changed when you did the brakes unless you removed the main axle nut. Here is the exploded view of the brake disc and pad repair and the ABS sensor. Can you upload images of the left front brake assembly? Also, raise the front of the car up to see if the front wheels spin freely. Check out the diagrams (below). Please let us know what happens.

It was code C1233, and I just fixed it by replacing the tone ring. Very easy fix and seems very common for places like where I live in Michigan where the salt eats up that exposed metal tone ring. The error says it's the sensor when it's really the ring the sensor is reading is cracked. This makes sense because the sensor is reading the ring for wheel speed, and it takes a minute or 2 for the sensor to figure out something is wrong with the ring, throwing the code, which is why I had the delay for the lights going on every time I started the car. Thank you for the diagrams!
