To have that many codes, look for something in common. That means the 5.0 volt supply to all of those sensors. Suspect a broken wire or stretched pin in a connector. The easiest is probably the TPS. Back-probe through the connector. One wire must have 5.0 volts. If it's missing, follow that wire back to look for a break in the circuit.
Also, with the ignition switch off, measure the resistance of the 5.0 volt feed wire to ground to see if it's shorted.
