No. The speed sensor is located on the transmission, and is what drives the speedometer cable, which drives the speedo head. The speedo head is another name for the the speedometer, which is the display gauge that you see while sitting in the car.
The speed sensor is located in the speedometer assembly, at the back of where the speedometer needle connects.
There is no such thing as an "odometer sensor." There is a vehicle speed sensor that is located on the output shaft housing of the transmission. That sends info to the speedometer. From there, the speedometer and the odometer are both operated internally, so if your speedo is working, but the odometer isn't, you have a problem inside the speedo head assembly.
