I've replaced the right front wheel hub bearing assembly twice in a week. I thought might have a faulty sensor. Still getting a code from time to time c1233. ABS, check engine, traction off lights on. Sensor connector?, Wiring?, Or ABS controller?

If you have all these light coming on, I suspect you have an issue with the ABS module. However, you would normally have more codes then just this.

So I would suggest running through this test and go from there.

Also, below is the testing from the manual. Please let us know what you find with this and we can go from there.
