Answer 1

You have a intermittent sensor condition Hyundai has problems with the TCM ground . Without this proper ground you will code up,that or you senor get contaminated by magnetized particles in the transmission,You can either ground the PCM terminal  27, 6 , 18 . Or you can remove the middle console and get to its ( power) ground  G14
