PO122 code

[movin2stereo]

I got a code PO122 throttle/pedal position sensor/switch A circuit low input.What does this mean and what do I need to fix it?Would this have any effect on gas mpg?

About what it says. circuit low output.
A 4.3 should read .47 volts a idle
A 2.2 should read .2-.9 volts at idle.
Check the voltage on a scanner or volt meter.
If not in specs adj or replace tps sensor.
Also clean tbi butterfly.
