I want to say that it is located on the side of the transmission.
The speedometer and odometer signal comes from the ABS system via the wheel speed sensors.

It is called a APPS accelerator pedal position sensor. It is located on the front of the engine. It is the part that the throttle cables hook to.
there is a speed sensor on the side of the trans, where the cable used to be. unplug the wires and replace the speed sensor. pretty simple to do.
on either the top or the side of the transmission, if you find out other wise let us know I'm also installing a new speed sensor on my 2000 dodge, and according to auto zone that is where it is.... The speedometer sensor on a 1997 and before is on the tail shaft of the trans/transfer case. On 1998 and later the speedometer signal comes from the abs sensor on top of the rear axle.
If you know the velocity you can find the speed, you don't need a sensor.
The IAT sensor on a 2004 Dodge Neon is on the intake manifold. It is inside the number two intake runner.
