Hyundai Santa Fe - 2.0 CRDI 04r. The gas pedal reacts only pressed to the end

Hello
The gas pedal reacts only when it is pressed all the way down, the idle speed is raised to around 1200, the engine light is on, the error codes are U0002 and U0004, they are just about the gas pedal, I do not remember exactly. They can be deleted, but nothing changes and after a while they appear again. The problem occurred after the console was disassembled, the installation checked, all plugged in as necessary, after a small exchange of two plugs, from heating the driver's seat and adjusting the height of lights, I do not think that it had any impact, but it happens differently. The voltage in the plug from the pedal appears, from what I remember, it was 5V on one of the pins and 6.2V on one. Is there a problem to find here
And even after erasing errors and unplugging the gas pedal, it does not immediately fall into error, just as if I disconnect, for example, a flow meter, it will not show an error.
I am asking for suggestions

A pedal released or a module. Start by checking the resistance on the pedal or changing depending on the pressure.

The resistance on the pedal was checked and it was not completely compatible.
A similar topic is in this forum and the resistance did not match, however, it was not a gas pedal so I do not want to take unnecessary costs. Before dismantling the console, the pedal went without a hitch

Yes, it worked. Installation checked, all connected. The problem is only with this gas pedal, the rest works

The problem is that swapped cubes could burn everything. ECU may well be released: /

What is your traction system there?

Normal ABS or ESP is?

Is the hyundai or everything separately on the CAN bus?

It seems to me that this potentiometer on the gas pedal disturbs everything. Or how not the motor controller is released.

But if you have this hyundai on CAN, it's an ESP failure (if ESP is there) it can theoretically cause the engine driver does not know what it's doing.

Replace this pedal potentiometer at the beginning - and there you have to replace it because even if it does not cause a problem today and so in a few weeks or months the problem will come back because of this pedal.

The problem is probably solved. The most important matter has been omitted. The driver is flooded by a leaky heater. We'll see if it can be saved. Thanks to everyone for the suggestions
