One month ago I ran over a very big bump on the highway and my ABS light came on  
  
  
  
 Two weeks ago I ran over a little bump on the highway and my ABS light came on  
  
  
  
 Last week I ran over a little bump on a neighborhood road and my ABS light came on  
  
  
  
 Now every time I bounce a little while driving the ABS light comes on  
  
  
  
 When I turn the car off, then back on, the light is off  
  
  
  
 Does this sound like a problem with a sensor?  
  
  
  
 The car has new brakes, rotors are 1 yr old, and I replaced a bad wheel baring 2 months ago  
  
  
  
 Thanks

It’s probably a sensor or a wiring/connector issue. I would take it to a good independent mechanic and explain to them about hitting the bumps. Waiting is not going to fix the problem.
