Both of those codes are for the transmission
720 is Output Shaft Sensor Generator B

705 is Automatic Transmission Range Switch Problem this is the Park,reverse,neutral,drive, low Switch that tells the computer which gear you have selected. Hope this helps From my experience this type of problem has to either go to a FULLY EQUIPPED TRANSMISSION SHOP OR THE HYUNDAI DEALER a regular small auto repair shop is nor usually equipped to do this and costs you extra money due to their lac of knowlege in this area Actually the Dealer is the most knolegeable of this due to they see it repeatedly and have all the tools and parts right there on hand to fix it right the first time.
If you find this information helpful please give me a Fixya! Rating and anything i can do to assist further please contact me ,Thank you,Randy

97 grandprix code p0705 no check engine lamp on, but 1-2 gear shift is exteneded, then shifts also my scan tool shows 1-2 sel opn or shorted to ground..after driving for min but no code for sel yet

I just answered a P705 question that may be connected to this.
But I will add that usually transmission codes will not turn on a check engine light. The reason is the check engine light is to warn the driver that something has happened that could damage the cat converter or cause major problems with emissions.

Hello.. my 2002 Mercedes benz S320 idles but does not rev at all and has a check engine light on can anyone help please

Sounds as if it is in emergency service mode , if you can obtain or borrow an OBDC II reader ( I thinks it's OBD2 for that model ) it will show you the scan of the engine management diagnostics and give you fault codes corresponding to the faults in your car ( Know as DT's ) look on the Mercedes forums and they will tell you what fault codes mean .

Hi Iv just bought a Volkswage Touareg 07 plate 3liter v6 and the emission control light has come on the dash. I got a diagnostic check done today at the local garage and it's showing fault code 212597 can...

That code must be unique to VW because it has no relationship to the obd, eobd and jobd codes required by law which all ordinary mortals must use.

Generic codes have universal meanings and are known as PO codes.
Some codes are model specific and are known as P codes or are plain numbers but I haven't known any with so many digits.

Which codes are used depends on the diagnostic equipment that is available and the amount of model specific information available.
Sorry I can't help further. I feel you need to approach a specialist or to post your question on a forum dedicated to your type of vehicle.

What does a lightning bolt on dash mean on a 2006 vw beatle?

It means there is a "Diagnostic Trouble Code" Stored in your On Board Diagnostic System.

Your On Board Diagnostic (OBD) System is a computer that monitors the sensors and readings of your vehicle.

So the light means "Something weird is going on.". If you want to know what that is, you'll need to have the vehicle scanned using an OBD scanner. There are tools for sale to the public, and every dealership has these. AutoZone also has a scanner they can use to help you identify what part to buy to fix the problem.

Can you tell me what the below codes mean. I just when to Auto Zone and had a diagnostic scanning done. AA- bank 1 AA1 aa2 aa3 aa4 Thank you.

I also work for autozone, 5+ years, and these are not trouble codes. I would find another Autozone and have them re-read it. Trouble codes would look like this: P0300, or P1756. The codes you have are not correct. Also, they should take you inside, look up the code, and explain what they mean. Also. ask them to print them out.

Engine light came on. Car has 53000 miles. No noticeable prob when driving. What could light mean?

Could mean anything from a loose gas cap to a major engine problem, Go to your local auto parts store and get a free diagnostic scan and post back the code if it is not explained when tested.

Transmission is acting up,went to autozone and it shows 2 codes p1529 and p720 please explain ? thanks Ralph

P0720 almost always points to a problem with the output speed sensor itself. The sensor is located on the top of the transmission near the rear. It's held in place with one 10mm bolt. You may be able to access with a long extension and a 10mm swivel-socket. If not, you'll need to remove the air box. You'll find the sensor semi-hiding under the wiring harness that runs across the rear portion of the top of the transmission.

P1529 is simply an indicator that the transmission control module (TCM) requested the engine control module (ECM) to turn on the check engine lamp.
Let me know if this helps or if you need mor help.

Code p72o & p1618 &p1633 on my s80

the P720 (which i'm guessing is suppose to be a P0 or 170 means its transmission related...i dont know what the 20 stands for thats the exact specific code/problem but it gives you an idea...the two P1600 codes are Manufactur made and they are both about PCM-Auxiliary Devices..

So i'm guessing that the one that is making your car not move is the P700 code..

hope that gets you started
