As opposed to what way? The only way to do it is to use a volt meter and measure the voltage on the wires going into the tps (+ on green, - on black). Then adjust the tps by unscrewing the 2 screws and rotating it until you get the desired voltage (~.98vdc)
Thats the same way not another way. Do you have aftermarket TB? If not and your having idle issues more than likely a tps could do the trick. If not take it back or leave it on its not that much dinero.
