Engine Code P0123

My check engine light has come on P0123 Throttle/Pedal Position Sensor A Circuit High Input. What would cause this? and what is the solution? Thanks

I just got the duralast one at autozone as a last resort because my emissions are due in two days. Strange thing is its reading code p0122 and p0123 so evidently the voltage from TPS is too high and too low. sounds too weird to not be a bad TPS ...
