Ford F150 5.4 Liter

[Cicada]

I'm getting a P0123 error code.  Comes up with Throttle Position Circuit High Input and Throttle Sensor Out of Range came up.  Any idea what all possibilities come with this?

Do you have a code reader?  Try erasing it and see if it goes away?  The best investment I made was buying a cheap code reader for like $59 at Fleet Farm. I have cleared codes on 3 different vehicles over the years that I never had to bring into a shop for.  Most of them are just hiccups like misfires, once cleared they go away.   Most car dealers will charge around $80-90 to do a "Diagnostic".  I've paid for the thing 10 times over already.

What year?

[Cicada]

I do have FIXD and that is where I got the code from.  I have cleared one code in the past, but this one came back.

It is a 2001.

Check your throttle position sensor voltage. KOEO you should see .8 to 1.0 volts with the throttle closed.
