traction control and abs lights randomly come on

so my 2007 trd off 4.0 2wd has both the abs and traction control lights coming on and turning off randomly and now the traction control light stays on but is dimly lit any ideas

 

bump

 

have you cleaned your wheel speed sensors?

 

yes it only happens when its raining im thinking the water is getting in the sensor but that makes me think they nee to be replaced because wouldnt you want abs and traction control in wet conditions even more so lol

 

have you checked your wheel bearing?

 

no had no idea the wheel bearing would do anything please elaborate im not familar with these sensors honestly
