so I've taken it and had diagnostic test's done... and its throwing codes p0732 ,p0733,p0734 But everytime I drive it, its in limp home mode (where it is in 3rd from start to stop) . And it also downshifts from 4th gear to 3 rd gear when the speed reaches 65 kmph and gets stuck in 3 rd gear then I have to restart the car aI am scared that its reall bad on my car does someone know how to.fix this

You need to look at the live data. See if you can force it with the scan tool. If you can it eliminates the internals.
All those codes pretty much say that transmission fluid is low and/ or dirty causing the shift solenoids to not function.
How old is your car and what mileage?
Transmission fluid ever been changed?
I pretty much guarantee this to be your issue.
Good luck.

Hey can anyone tell where is the camshaft sensor and crankshaft sensor located in hyundai accent 2012 1.6 SX o automatic petrol
Do you want to try DIY drain/refill and filter change? Est. $100 ATF + $45 trans filter/gaskets.
This will allow you to inspect the magnetic drain plug for metal contamination, inspect the fluid, inspect the filter for metal and inspect the internal for metal. At least this will give you a good idea of the damage or no damage.
1). Locate the Transmission magnetic drain plug. Depending on model yr. it might be 28 to 32 mm. Hex. Get drain pan and place white napkin at the bottom Pan. Remove the magnetic drain plug. Inspect the magnetic drain plug for metal particles. At 100K miles a little metal fuzz is OK. Metal chips are bad. Clean the drain plug with white napkin. Keep the napkin to inspect for metal shavings and chips.
2). After draining the ATF into the pan with white napkin, roll the liquid around and see if there are metal particles on the white napkin. The fluid might be dark brown. New fluid is clear red. If the ATF smell burnt, that’s not good.
3) Locate fill plug and the bolts along the side mounted transmission pan. Remove the fill plug before remove the pan. If you cannot remove the fill plug, STOP. You will not be able to tell the fill level of the transmission. Proceed only if you can remove the fill plug. Clean the case and remove the old gasket. The transmission filter can be removed and inspected for metal and contamination’s. The inside of the transmission can be wiped with clean napkin and napkin inspected for contamination and metal. If there are no metal shrapnel, you might be able to recover the transmission. If there are lots of transmission shrapnels, you might want to stop. Seek a used transmission to service or purchase a remanufactured transmission.
Go further with DIY, only if the transmission did not have metal shrapnel.
Purchase the Filter/Gasket kit and replace after clean wipe the bottom of the transmission. (If you are adventure some, you can remove the valve body and clean. You must be very careful attempting to remove the valve body, there are tiny metal ball valves and springs. You cannot lose the placement of these metal ball bearing valves and tiny springs.) Use new Valvoline MaxLife Full Syn ATF on napkin to wipe the bottom of the transmission case. Put ATF in a spray bottle to clean the valve body. Place new gasket on the side pan. Leave the fill level plug out.
Put the magnetic drain plug back and torque. Use a transmission oil pump and add ATF from the fill level plug hole. The transmission will take 5-6 qts of Valvoline MaxLife Full Syn ATF ($18 gallon). This is much cheaper than Hyundai ATF and is compatible. Valvoline MaxLife Full. Syn. ATF have a lot of detergent. Therefore you can perform a 4X drain flush to clean out your transmission. This procedure is used because you cannot drain the torque converter and valve body.
1st flush 50% clean, start engine and see if transmission work and can drive around the neighborhood until the engine get to operating temp. Manually shift through the gears. Turn off and let cool. Drive 50 miles before the 2nd flush 75% clean, Start and drive through the gears, get the engine up to operating temp. Check how the transmission shifts through the gears in manual mode. Drive 100 miles, then perform 3rd flush 82.5% clean, drive 100-500 miles, 4th flush est. 92% clean. On final flush add 1 qt Lucas Full Synthetic ATF Stabilizer ($9-$12)
Check the fluid with each flush and keep a sample in clear water bottle container. The first 2 flushes, the fluid will still have a tint of brown and not clear. The fluid will become more clear red As you continue with the flushes.
On the last flush, put 1 qt Lucas full syn ATF stabilizer ($9-$12), then top off with Valvoline MaxLife Full Syn ATF.
Drive 500-1000 miles and see how your transmission shift through the gears in manual mode and automatic mode.
The Hyundai Automatic Transmission have adaptive-learning. If after this cleaning flush, it is driving ok. You’ll need to clear the codes and reset the transmission adaptive learning. There are two method to reset the adaptive learning. Pre-2006 you can disconnect the battery ground for 30 minutes. Reconnecting the battery will reset the adaptive learning to factory default. Newer cars will require dealer reset adaptive-learning and very specific driving speed and engine rpm to get the transmission to learn.
I know this was long, but it’s the only method I know how to determine the level of damage in your transmission and flush/cleaning method and getting the best (least expensive) method to refil the transmission. Estimated cost sub-$200 + dealer code reset and transmission adaptive learning reset.
