Welcome to the site. Do some researching and reading but you might find it to be the wheel sensor in the front drivers side wheel bearing hub assembly.

 

Is ABS on wheel hub to check on loose the plug on front drive side ? Last summer I replaced Wheel Hub twice in 4 yrs and not there on abs senor plug on passager side. Thank Weedhoe
