What does OBDII fault code P0120 really mean?

Question

What does OBDII fault code P0120 mean? The device said: "TPS/Pedal Position Sensor A Circuit Malfunction". The problem is that TPS stands for: "Throttle-body Position Sensor, which sits under the bonnet on the throttle-body. The Pedal Position Sensor, on the other hand, is located on the accelerator pedal. I assume that one of the two sensors is faulty, but which one? Or could it be that both are faulty?
Besides the "electric fault" warning icon frequently coming on (it goes away when I restart the engine), the problematic vehicle has recently become hard to start in the mornings, and has had two recent incidents of uncontrolled acceleration.
It should probably be mentioned that the vehicle in question is a Renault Kangoo.

TPS stands for throttle position sensor. In drive by wire there are two throttle position sensors. One is a throttle body position sensor and the other is a pedal position sensor. The P0120 fault codes refers to the pedal position TPS.
