2002 Hyundai Santa Fe Speedometer problem

    It is neither the output speed or input speed sensor. There is a Speedometer sensor on the lower part of the transmission Yes it is the VSS it is hard to see from the top, but you can get to it from under the car. That is what runs your speedometer. I replaced my about 3 months ago. There is a Korean Auto parts store on the web where you can get it.
  • Thanks for the input. I found a parts dealer,FourGreens, that has the VSS. They sell through E BAY. I haven't got it yet but I believe this will fix my problem. From all the other posts this seems to be a common problem with the Santa Fe. Thanks again, Tom

    I assure you that will fix your problem. I see you located where it was on the transmission right? Actually it is very easy to install from under the car. One bolt and it comes out. Push the new one back in the hole, put the bolt back on and install the connector and you will be good to go. "Note" Do not over tighten the bolt it is fairly small and you could bust it off. Just snug it up.
  • I have searched the transmission over and over and the only senser I can find is located on top of the transmission just under the air filter box. I removed the air filter box and the senser is looking me right in the face. If there is another senser, I can't find it. This is a 4WD drive transmission and I am sure there is a difference between it and the 2 WD. If you have other input I would greatly appreciate it Four Greens auto parts had a picture of the speed senser and it looks exactly like the one I pulled out.

    topcat: If it looks exactly like the one you pulled out, then it is probably the right one. Does it look like the one on this web page, the second one from the top? And costs $32.90?

    And say it is a Santa Fe Vehicle Speed Sensor Sonata Sedona Kia Amanti? If so it is the VSS that you need.

    Didn't know yours was a 4WD, so they could be located in different spots. But if it looks like the picture then it is it. The other sensors look different than that one. ">

    Topcat: Does the one you pulled out have a gear and a shaft coming out of it?? If so it is probably the right one.
  • Finally found the right sensor. After seeing it I felt like a fool for not seeing it before. However I ran into trouble getting it out. It was so stuck it was almost like it was welded into the shaft hole.. I had to take it out in pieces. Hope I never have to change another. The teeth were broken so it couldn't have been spinning so the Hyundai dealership couldn't have tested it because they told me it was the speedometer cluster that was bad. Spent 300 dollars that was unnessary. Anyway thanks a lot for your help

    So I take it you had to replace the gear also? If so, where did you get the gear, at the Hyundai dealership? I bought one, but mine was good so I really didn't need the new one, but replaced it anyway.

    Another question topcat, did you take it out from the bottom of the car or come down from the top?

    Can you tell me if the vss speedometor sensor also controls the radio,gas gauge, fan for the air cond and speedometor? I am having problems with all of these things. The hyundai service center is saying I have to spend $99. to do a diagnostic test to find out.
  • verno1verno1 Posts: 13
    No as far as I know it controls the speedometer only. Not all of those other things. You sound like you have some strange electrical problem. But it wouldn't be the Vehicle Speed Sensor.
  • carcapcarcap Posts: 5
    Thank you, At first it was the gas gauge going to empty. Then the radio started going on by itself. Then the fan, had to play with it a little before it would turn on. Now the speedometor goes to zero at times.
    I guess I have to bring it to hyundai for a test. Hate doing that.

    Do you happen to know what might be the cause for several things happening all of a sudden. Gas gauge going to empty, radio coming on by it self, speedometor going to zero at times and fan acting up?
    I thought it might be the vss sensor but that controls the speedometor right? I may just have to bring it to hyundai for a diagnostic test.
    Sorry if this is a duplicate post not sure about this site.

    to Topcat or any else that might know.
    My issue is with the speedometor, radio,fan and gas gauge. All are acting up. Is there a sensor for all of them? Thanks

    Where exactly is it located. Do you access from top or bottom. The pictures in the other post is showing what I believe to be the output sensor(has a 10mm bolt for removing) not the speedometer gear unit. Is it the unit under the air intake kind of below the battery(left end of battery) that has a "C" clip holding it? If it is and 4 pins connector(not 3 pins as shown in pictures), then after you remove the "C" clip do you pull straight out or wiggle it out?
    Thanks.

    Hello posters.
    It is great to hear you got your problems fixed but could really help others if you give a little more detail information. Like where exactly it is and how to access.it. Others have posted they found sites with pictures and it will help if you could include the links or the pictures.
    Thanks.

    The one a little left of M/C and down has a 10mm bolt holding it. I took it out and it does not have gears on it. It is just a sensor module. Do I have to remove the engine cover to see it? I have hooked up a computer analyzer to the OBD and test driven the car and all speed sensors are working. ie. every speed parameter; trans, wheels, engine are feeding back to the OBD readout so I am almost positive the problem is like most have described as stripped/broken speedometer gear........But where do I find it, how do I access it and how many pins on the connector? I see another connector a little forward of the one described above with a 4 pin connector and a "C" clip holding it. I tried taking the unit out but it was tight and did not want to break anything unnecessarily. Is this the correct unit and what's the trick in removing it?
    Thanks.
  • I had the same problem and changed the VSS, bought it from FourGreen but it didnt come with a gear so i replaced the sensor by itself. Before the speedo or the odometer didnt work and now they work but the speedo bounces alot and the crusie control surges when i use it. I think it may either need another gear which i dont know where to get one or it may have a bad connection. It has a short pig tale from the sensor to anotner plug connection and i am thinking this may be bad but i dont know where to buy on. If anyone can help me find the pig tale connector or the plastic gear that would be a huge help.

    When you pulled the sensor out did it have a gear on it? If not the gear was hung up in the hole. You can get a new gear from Hyundai. I would pull the sensor again and get the gear and replace it. You are sure you bought the right sensor aren't you.
  • There was a gear but it looked ok, but I didn't have one to compare it to. So I can get a gear from Hyundai, but where can I get the pig tale, hyundai? It's acting like a loose connection, could that be the worn gear as well?
