Engine starts, idles but will not rev.

HI, i have 2001 clk430 and it is as though the accelerator is not conected, the car just idles with no pedal at all.(engine check light is on) I scanned the car with my OBD2 scanner and got a PO121 code (throttle/pedal sensor/switch circuit A problem). I bought a second hand sensor (Part number A012542) and plugged it in with no change. Do i have to do a reset before the new sensor will work? or is it another problem entirely? Does any one know of a way to test the sensor as the pins are numbered in the plug housing? Any advise welcomed.
