Accelerator pedal has the Pedal Position sensor.
Throttle (on the engine) has the Throttle Position sensor.
I am afraid you've changed the wrong one.

2 possibilities:
Either the new switch is defective or
The Solus is not showing the right opening.
Try reading with EOBD, maybe you can see the pedal position.

The chance of the ecu being defective is a lot smaller than the Solus being wrong.
How does the car drive now? Any problems?

What's the description in live data? Pedal position or Throttle valve?
