Question FAST 90 mm TB. TPS reads 0% at all throttle positions. Which wire? Sensor?

Just got the Firehawk back from the shop after a H/C/Intake swap.

Can a bad TPS sensor cause this? Or a wire, and if so which one?

I'm also getting DTC 122 and 443.

Thanks for any assistance!

Ttt

Still trying to fix this. I swapped the TPS sensor with a brand new one with no effect.

I still think it's a mechanical/electrical issue.

I have an appointment with Formato tomorrow afternoon. I have never dealt with his company and only know OF him through the forums. I am PRAYING he is a professional and knows his stuff.

The Miami shop that did my current work eg.

H/C/I swap and replace my leaking oil pan and shot master cylinder. Other than that EVERYTHING on my car was in perfect working condition with all parts present and accounted for.

This is what I got back:

They had my car for 2 1/2 months and told me for the last month and a half it would be done next week ... They said that every week.

They did NOT replace my master cylinder.
My PCM diagnostics port was NOT working.
The oil pressure and coolant temperature A-pillar gauges were NOT working.
My TPS is NOT functioning/powered or whatever (preventing any ability to tune)
2 gorilla lug nuts were NOT on the front wheels.
One of my Firehawk center caps is NOT on or IN the car (they are out of production and cost $100-150 used ... IF there are any for sale).

im gonna say that if you replaced the tps sensor..youve gotta have a fault somewhere in the wiring, i dont know if you know how to follow schematics..but id ohm out each wire that goes back to the pcm to check for any breaks in the wiring.

it should be the blue wire out of the 3.. the same one you can use a ohmmeter on to determine volts = % throttle blade open.. I'd stick a small needle in the blue wire, take an ohmmeter, turn the car to ON but not started, and try to get a reading from the blue wire to see if that is the problem.
