p0705 code

[attickt]

ok there isnt much on here or any other forum, or seemingly anywhere on any database....and there is ONE thread referring to this code.

my car started acting up sunday night 01/20/13 after i had done an oil change on Saturday, put a full tank of gas in, and got a car wash on saturday. sunday night around 8pm i was leaving my dad's it was about 25 degrees out, i started my car....and it stalled out ( i drive an automatic....that a long story) confused i thought maybe i had forgotten to turn her on.... but recalled turning her on..... i then heard a high pitch humming like an electric motor and she started to rise and drop in rpms and bog out....my dash losed light.... so u put her in drive thinking maybe it was a battery issue.... everything worked fine....i made it 45 miles home....

this morning she started fluctuating in rpms but settled down... i made it to work... after work i headed to my friends house to use his obd2 scanner.... i made it 40 mins down the road went from 60mph to 15 mph my car could not locate drive, reverse, neutral 3rd or 2nd gear....just low... i had to pull over and my friend brought the scanner to me... it read P0705 Transmission Range Sensor Circuit malfunction (PRNDL Input)

which could be a number of electrical issue with the trans.... i was told it was a Farley easy fix but cant find any pictures information, tips diy's i cant even find the part!! and im really not looking forward to being shafted by toyota for something i may be able to fix my self....im not even 100% sure where to locate the part on my car...any help would be appreciated.... ive been reading nothing but repeat information just telling me what the code means....i know what the code means.... i dont know what needs to be done to fix it or any information and or parts....
