Okay, the code is for a circuit issue with the sensor, not the sensor. Techs are so quick to condemn a part by the code number. It said APP sensor so they shot it without verifying it is actually bad.
There is a wiring issue with the wiring between the sensor and the PCM.
I would replace your new sensor with the old one and take it back to them and have them do a proper diagnostic for the issue.
They should not charge you for that since they already failed at there attempt the first time.
The sensor needs 2 5 volt signals to it to work correctly. Sounds like one of them may be missing.

Accelerator pedal position sensor is mounted on the accelerator pedal bracket and it has 2 sensors to detects the accelerator position and a malfunction of the accelerator position's own.
The accelerator pedal position sensor is the voltage applied to the terminals VPA1 and VPA2 of the ECM changes between 0 V and 5 V in proportion to the opening angle of the accelerator pedal.
The ECM judges the current opening angle of the accelerator pedal from these signals input from terminals VPA1 and VPA2 and the ECM controls the throttle motor based on these signals.
If this DTC is stored, the ECM shuts down the power for the throttle motor, and the throttle valve is fully closed by the return spring.
