SOURCE: diagnostic codes p705 and p720
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

there is a short or a signal from the un-locking switch that is triggering your locks.
you have a switch manually to lock and un-lock your doors, the unlocking circuit is making contact.
you can try playing with your switch to un-short the switch or open it up ang check it.
tnx 4 using fixya,

The simplest thing to do is to reset the code and see if it comes back.
Next, check all wiring and connectors that lead to the speed sensor. The location of the sensor depends on your vehicle. The sensor could be on the rear axle, transmission, or perhaps the wheel hub (brake) assembly.
If the wiring and connectors are OK, then check the voltage at the speed sensor. Again, the exact procedure wil depend on your make and model of vehicle.
If everything looks OK, replace the sensor.
