Need help with a DTC ***P2123***

New guy here with a serious problem.

P2123 APP sensor No.1 circuit high input ON 1 CCM ´ (See DTC
P2123 )

This is the only code that is being thrown right now. Not exactly where to start. I did a search and didn't come up with a whole lot. The car is in limp mode and goes to about 3k rpm...

If someone could break down what "APP sensor No.1 circuit high input ON 1 CCM" means

APP = accelerator Pedal Position sensor...you have a problem in the pedal or the wiring harness between the pedal and the ECU...or possibly an ECU problem.

I would try another pedal first if the car was in an accident...the driver likely broke the pedal in the accident
