Measure the voltages on the throttle position sensor wires by back-probing through the connector. It needs to remain plugged in. One wire must have 5.0 volts. Usually that 5.0 volts feeds other sensors too so if you only get a code for one of them, look at the connector pins first for signs of corrosion or a stretched terminal that isn't making good connection.
