I've been experiencing hard shifting with my automatic transmission on my 2002 Hyundai Santa Fe for about two years now since I inherited it from my dad. I spent over $1,500 on a new A/C and they ended up havin' to install three of 'em all together before they found one that would work. The exact same problem occurred with my Hyundai Accent four years ago. There's obviously somethin' about Hyundai's and air conditioners that just don't mix. But I just had a friend run a diagnostic on the Santa Fe and it came up with this P0501 code and it's the first I've ever heard of it. I can't afford to put another dime into this piece of shit, yet it's the only piece of transportation I have left. I'm not really sure where to go from here, I'm severely handicapped and unable to do the work myself and I can't survive off what I get in disability as it is, so I can't afford to have anyone else work on it either. The only thing I can think of at the moment is a relatively small explosive device strategically placed under the hood and one just inside the firewall might do the trick. I hate SUV's anyway, I've always wanted a truck instead. : )

my vehicle is Elantra 2005 without ABS so i want to know witch sensor should i replaced
i just have one sensor attached on front right wheel
but when i search for this sensor i found that is belong ABS models -
The Engine Control Module (ECM) calculates the vehicle speed by reading the signal from all the "Wheel Speed Sensors", unfortunately the P0501 code doesn't specify which code is the problem. I sugges visual inspect all the wheel speed sensors. Are there any other codes?

Im getting the same code on my 2010 Accent auto. P0501 Speed sensor A is the reading i got. Its proving to be a difficult problem to fix. Some people are saying its the output sensor in the transmission and other are saying its a wheel sensor? Is it the wheel sensor or trans? Because the article above says Speed sensor A is from the transmission as well. Any advise is appreciated.

Unfortunately not all the makes and models are the same, and the description above is a general description. According to the factory service manual, for you model and year, the P0501 is for the wheel sensor.

I am having the same issue. I have PO501 Vehical Speed Sensor A Range/Performance. I have an 2005 Hyundai Elantra and need to know where to go to fix it. Any clarification would be appriciated. Also not sure where its located? Please Help

According to the factory service manual, the first thing you need to know is inspect the "Right Front Wheel Speed Sensor (WSS) ". Make sure the wire is OK and that the sensor is clean.
Here is and image from behind the wheel area.

I am having a 2002 elantra gt automatic american specification and have been experiencing delay in changing of the gears and a hard shift which makes the vehicle gearbox vibrates when it changes suddenly,pls l need help urgently thank you.

The problem is probably one of the ABS wheel speed sensor, the problem is that more test needs to be done to find which sensor is the bad one. Have you tried clearing the code?
-
Where exactly is the ABS wheel speed sensor located or mounted on the vehicle and how it cause that problem,because a diagnostic machine detected this sensor code P0501 SPEED SENSOR 'A' and can this code be cleared. Thank you

I have a 2003 Hyundai Tiburon 2.0L that is throwing the P0501 code. The mechanic told my step-son that it's not worth it to be fixed. I am concerned for multiple reasons... Leaving a vehicle with a check engine light always lit up could be cloaking a different issue (big or small). Another reason, what are the possible ramifications of driving in this condition? Can this be a bigger problem if not taken care of? or is this a code that is a front for another issue (big or small)? I do want my step-son to figure things out for himself, but if he is without a car, mom gives hers to him and she takes mine... I don't like to be without a vehicle (if you know what I mean).

You should get a second opinion. More than likely, the mechanic does not have an idea of what the problem is. The most common solution for the P0501 code on your vehicle is the ABS Wheel Speed Sensor. A mechanic should be able to read the ABS Wheel Speed Sensor signal with a scanner to determine which sensor is the problem. Once you know which sensor is the problem, then clean or replace the sensor. Have your car had any damage around any of the wheels?

I have a 2006 Hyundai Sonata. I have just replaced the output speed sensor after getting the P0707 code. Now after replacing that I'm getting a P0501 code. Both times my ABS light has been on, for awhile it was on and off but now it seems to be staying on but I wasn't getting the P0501 code before. Is it cause I replaced the output sensor or is this code more for a wheel sensor? Was shifting hard and missing before the output sensor. Seems to be running fine at the moment. I'm curious as to where to start to look to now fix this P0501 code problem now.

The most common problem for the P0501 code on your vehicle is the one of the ABS wheel sensors. Unfortunately, the code doesn't indicates which sensor (of the 4 on your vehicle) is the bad one.
I recommend starting by checking the tires. If one of the tires is worn out, it could set the code. If all the tires are OK, then you need to check all the wheel sensor. Make sure the sensors are not damage.
Here is the location of the one of the Front Wheel ABS Speed Sensors:
