Unhappy

i went to the dealer today and they told me that i need to replace my input and output sensors. they gave me two codes P0722 and P1525, i don't know what the heck these codes mean. all i know is that these suckers need to get replaced. they want to charge me $400 for it but i can get the parts for $140 so i figured i could do it myself. the only problem is i don't know where exactly they are. all i know is that it is outside of my transmission. can anyone help me locate them? i'd appreciate the help.
just for lil background on my car problem: the car starts fine and i'll be driving down the street and my car will go bump and the gear shifts to 3rd. it'll stay in 3rd even if i'm stopped and i can manually change it 2nd but that's it. it won't go down to 1st and it won't go up to 4th so my car only goes 55m.ph. can someone help me please???

Look around the area where the Dip Stick for the Transmission Fluid is, It should be thee protruding with two wires..... That's where mine is...

THE SENSORS ARE MOUNTED ON TOP OF THE TRANS. ONE IS BELLOW THE BRAKE MASTER CYLINDER AND THE OTHER IS BELOW THE GEAR SELECTOR CABLE .YOU MAY NEED TO REMOVE AIRFILTER HOUSING TO GET TO THE ONE BELOW THE CABLE. AFTER YOU REPLACE THEM DISCONNECT BATTERY TO CLEAR THE CODES.

Hi I'm a new recently member after reading this post.
I have had the exact same problem on my 2001 Sante Fe, for a couple of months now. 1st intial problem was a P0715 input speed sensor fault. I ignored it after it went out for awhile. Well problem came back this time with a P0720 output speed sensor fault and the same original fault. I drove this thing for awhile, while the transmission would do the fail safe down shift into third occasionally. These have both since been changed with the same exact problems and faults from the hyundai dealer with in seconds after it was serviced so I drove it back. Know they want to rebuild my transmission and refund me on the sensor work. There saying the transmission got so bad from driving it the way it is, and not changing the tranny fluid out on it's normal maintenance intervals. So here I'am with a bad transmission now and probally $2500 dollars worth of work. So I may sell it as is to the 1st available buyer from where I'm at, I've had it long enough and I'm ready to get rid of it. The moral to this reply is I would not drive the vehicle longer than you have to with those sensor problems!
(P.S.) do not buy a sensor from Auto Zone they sold me the wrong sensor not knowing exactly what it looks like ie.. vehicle speed sensor for the tranny instead of trans axial speed sensor.
Good luck,

Hi everyone,
This is my very first post here. I own a 2002 Hyundai Sonata GLS V6 since 6 month. I bought it at a private party, and the Yellow spot Check Engine was already On. As I had a very good deal with this car, i bought it. The car was great, but the check engine came back on every time i brought my car to the Hyundai dealrship. They changed several pieces of my car, like the 'canister'.

Now, when I drive, the car may shift down to 3rd speed on the freeway (as described above), which is very dangerous. The dealer told me it was due to the speed sensor (he checked the error codes with its computer). I have an appointment Tuedsay to replace it, they want to charge me for $300 (I don't plan to do it myself anyway).

Is the price right ? Is there a Hyundai financial rebate for this ? Has someone made the part replaced successfully ?
Do you think the yellow spot check engin will go away for ever ? I am fed up to rent a car each time I go on hollydays as I cannot rely on my own car !

Thanks for your help, sorry for my english,
JB

I'm glad I found this thread!

I had my output speed sensor go bad about 4 years ago the first time in my 2001 Santa Fe 2.7l 4wd. Symptoms were the same as others have mentioned. Would be driving down the highway and the car would slam into 3rd gear, revs would go up, and the CEL light would come on. I could pull over, turn off the key for a moment, turn it back on - and sometimes it would clear and sometimes I would just drive in autostick mode (manually shifting up and down.) When it would experience these symptoms, the only 2 gears you could shift through manually were 2nd and 3rd. Turning it off and back on would bring back 1st and 4th...at least temporarily. So if you are experiencing these symptoms, there's a trick to get by for awhile (though I wouldn't drive like that too long.)

Anyway - I started having the symptoms again about 2 weeks ago. I knew immediately what it was - and went and got the codes read to confirm it. The first time I paid a mechanic to fix it (local) and I think it was around $175 - not too bad for part and labor. This time I wanted to try and do it myself. When I found this thread, I figured I could get to it and give it a shot.

I found the output speed sensor on eBay - a genuine Hyundai OEM part - for about $50 shipped. The part number (from the factory packaging) is 42621 39052. The part bag has both the Hyundai logo and the KIA logo on it - so they might be available through a KIA dealer as well. Using the PDF diagram of the tranny from the post above, I easily located the output speed sensor. I did have to remove my air filter box - but it was right there underneath it. I saw another post somewhere online where the guy said it was back under the #2 cylinder. He said he also had a 2001 Santa Fe - but his must have been different from mine. There was no problem at all getting to it. Took my maybe 10 minutes to do the work - which did fix my problem.

I'm posting this in the hopes that it may help someone else in the future - and I appreciate all your posts as well. Thanks!

Hi tbedave,
I have the same issue as well on my 2001 Santa Fe just like yours. Just wondering do u need to unscrew anything on your output sensor to put it on?
I'm new at this as well and was thinking to get the part on ebay first and fix it myself if it is pretty easy to do it.
Seems like a plug and play type of fixing which i think i could do...let me know if i'm wrong..hehe. :- )

If u don't mind, can u please give some advice on the steps that u took to fix yours ?
The mechanic told me he will charge me $103 for the sensor and labor for $60 per hour.
That is a lot and i hope u can give me some pointer :- )
Thanks for your help :- )
