MT/AT Encoding Sig. Error what does that mean?

Question

my 2001 Hundai accent is reading the codes ENGINE- P1586 , P0326 , P0326 ,

A / T - P0707 , P0733 , P0722 , P0734

the engine is doing a knocking noise

Answer 1

P1586  Manufacturer does not provide any information about this code

P0326 Knock sensor code

P0707 Transmission range circuit low input

P0733 Third gear system malfunction

P0722 Pulse generator B open

P0734 Fourth gear system malfunction

P1586 is related to the range switch selector having a low circuit input this is known as the PRNDL, P0326 if your engine has a knock then of course you will code this up, make sure you have enough motor oil, inspect the motor oil if its is silverish in color you will be dealing with a mechanical condition, P0722 this code will be responsible for 3rd gear and 4th gear malfunction.
