way too much money, the sensor is outside on the inside of the front bumper and the lcd readout is reached by pulling out the instrument cluster and simply removing 2 screws, I would look for a used one or buy a used insturment cluster and take the readout from that, removing the cluster is easy, search the site for pictures and instructions, the only thing I recommend is to bend a couple nails instead of wire to use to extract the cluster as the wires will bend and the nails will not and it will be easier to remove
