check the maf sensor, is it clean? if not get some maf sensor cleaner and clean it. dont rub it with anything though. just spray it down with the cleaner you can usually see the gunk buildup on the resistor.

Looks like a wiring issue for all those sensors to suddenly read 'bad'. Check grounds. Those sensors may share a common ground.
