Acceleration problems after wheel speed sensor replacement

[tterpenning77]

Hey, new here, I have a 2011 chevy traverse, the abs and traction control lights came on and it was acting strangley while braking at slow speeds, code reader said drivers side wheel speed sensor so I replaced that today and now it accelerates slowly and the speedometer is not working properly (says I'm going 100 when I'm going what I believe it 55 lol). Any idea as to what's going on? Thank you in advance!

Did you do anything that would have effected the vehicle speed sensor?
