P0705 - Transmission Range Sensor Circuit Malfunction

I have a 2001 Focus Se, Zetec engine.
Today I got the check engine light on, the code I got was P0705 meaning Transmission Range Sensor Circuit Malfunction (PRNDL Input).

Does anybody know what exactly this sensor does and what to do about it?

Thanks.

im assuming you have an automatic (ATX). sounds like the ECU lost track of what position the shift lever was in. possibly just a fluke.
this is what i would do
reset the ECU by disconnecting the negative terminal on the batter for 15 minutes.
reconnect and go for a drive. more than likely, this code will not pop again. do you have any noticable issues with your tranny?

Thanks scrammer,

Yes, I have an automatic transmission. I bought the car 1 month ago, so far no problems with the transmission. The car has 60k miles and I had the transmission fluid changed already a couple of days after I bought it.

Now that I think of it, when I started driving today, by mistake I put the transmission in "2" not "Drive". This was before actually starting driving, just for a couple of seconds. After a couple of minutes I noticed the engine light came on.
Now that I think of it, this may cause the problem.

I will disconnect the battery cable and see what happens afterwards.

i had the same thing on my 04, i figured "lets see how she drives in 2nd" after about 3 weeks of owning it. um my advice, dont use it, cause i got the same code with mine. luckly the dealership fixed it, they asked "have you been manually changing the gears while driving?" i was like no.... it did drive different too, felt like it took longer to shift and would kinda jolt when it did. also the over drive light went on, then after a while the check engine light too. o yeah and mile gas milage sucked too, for the week or so it took till i got it fixed.

Arrow

did you get that fixed???? I have the same problem but I can feel the transmission that it looses track of where it is.

i.e. I put it in reverse and it kicks back but the backup lights don't turn on.

Did you replace the sensor? did you clean it? how did you replace it? is there a DYI somewhere?

thanks for any help!!!

ditto-dealer put in a used tranny after mine blew, and a week later i had his issue-now they want another 150 just to look at the tranny rather than the actual code issue,the sensor
sensors easy to find when on ramps, but Im havin a hell of a time gettin it unhooked from the wire-any suggestions for making it easier? I wanna give cleaning it a shot,or at worst replacing it myself

For me the problem actually ended up being one of the screws that holds the selector came out and there for was not actually shifting, once i replaced the screws cleared the codes i was rocking and rolling again.

Big *BUMP*
In searching for a fix for P0705 I found several threads asking for how to fix/replace/adjust with no answers in any of them. Now I'd like to give it a try.
Is the sensor position adjustable like neutral safety switches used to be? How do you align it properly?
IF nobody here knows then just ignore this plea like all the rest...
