There are three error in my Skoda  Octavia automatic 1 is transmission input sensor (g183). 2- SAE: gear lever x-y position sensor circuit   3- pressure control valve 3 (n217:) open 4- pressure control valve 2 (n216) what are these problems plz tell me my car is not shifting the gears.

Not sure about the specific fault codes, but it is unusual to get three different faults and a loss of selection. If you have detected the codes I presume you have a code reader? Have you tried to clear the codes?

Disconnecting the battery for 20 minutes can sometimes reset the ECU, but you may have reset radio codes etc.
