Question about Hyundai Elantra
Both of those codes are for the transmission
720 is Output Shaft Sensor Generator B
705 is Automatic Transmission Range Switch Problem this is the Park,reverse,neutral,drive, low Switch that tells the computer which gear you have selected. Hope this helps From my experience this type of problem has to either go to a FULLY EQUIPPED TRANSMISSION SHOP OR THE HYUNDAI DEALER a regular small auto repair shop is nor usually equipped to do this and costs you extra money due to their lac of knowlege in this area Actually the Dealer is the most knolegeable of this due to they see it repeatedly and have all the tools and parts right there on hand to fix it right the first time.
If you find this information helpful please give me a Fixya! Rating and anything i can do to assist further please contact me ,Thank you,Randy
