There are 2 microswitches under the squareish cover on the end. You could check these are operating OK with a multimeter. They tell the ECU throttle positions for wide open throttle and idle. Other than that I don't think there is anything in there that can go wrong.

I've not heard of any throttlebody parts going wrong although they can sometime need a good clean out.
