I just switched out MAFS sensor from my car. I disconnected the battery. (Negative only) and now when I turned it on there is a light with a car and a lock on the left side of my speedometer. I want to know what that is and how do I remove the light?

according to the owners manual, that indicates that the theft protection is active. It should go out when you start the car.
