I hooked my jimmy up to a scanner and it gave me 2 abs codes : c0221 and c0223. I cleaned the sensor port with 1500 grit sandpaper, cleaned it out, and replaced the sensor. Drove the car, light was off and then came back on. Hooked it back up to the scanner and it gave me 3 codes: c0221, c0222, and c0223. Please help

this can be poor connections at sensors and or abs unit. try putting dielectric compound at abs unit. It also could be a bad abs unit as well. a pro should check this for a short or bad unit.
