Hello there are two 02 sensors on this vehicle, 02 sensor 1 {pre 02} is located in the rear exhaust manifold. the second 02 sensor {post} is located in exhaust pipe just behind the cat. converter

On the 2004 impala the ABS sensor comes attached to the wheel bearing hub assembly. the hub assembly is around 100 dollars. If you are referring to the wheel speed sensor it is around 25 dollars.

Hope helps (remember rated this).

VSS is mounted on the transaxle.

If the speed sensor is for an Anti-lock braking issue, you will normally find 1 at each wheel (accessible when the wheel is removed). Another location would be on the transmission.

Should located on the rear cylinder head near the throttle body.
