The ABS light is still on my vehicle when I had the sensors(right/front) replaced based on the code of B0221. It did not solve the problem, but now gives me a code of B0221 & B0222(wheel signal). What causes this?? Help!!

Did you have the sensors replaced or the complete wheel bearings replaced?
B codes are body codes.
I think the sensors are part of the wheel bearings.
Did the mechanic check the OHMS on each speed sensor?

only the sensor because someone had cut it under my car. However, the wheel hub had been replaced back in July 2011. After that, I noticed that the ABS light would come on somedays and go off.

I searched everywhere and can not find B0221 or B0222
The abs sensor is part of the bearing.
You can replace the harness,but not the sensor it self.
You had new bearings put in front,so it shouldn't be the front sensors.
Maybe rear sensors?
When these types of cars get older,the clips break off the holder there
on,because the wheel is constantly turning and bouncing and the wires
tend to break off also.
I would have someone scan it for codes.
Most of the time it will save the codes.
These codes you can not read with an engine code reader.
It's a separate tool to read the codes.
