2001 Hyundai Accent - Page 7 Questions & Answers
Have 3 codes p0722,p0732,p0734 could they be all related and how do you check if the input and output sensors are bad
The codes usually indicate a bad sensor or something, if everything is working properly then you will not get a code. Need the codes defined and see which sensors they are related to. I always carry mine to Auto Zone but I think Advanced Auto Parts will also read the codes for free and tell you what they mean. I would happen to guess that other auto part stores do the same thing. I use Auto Zone because where I live all the workers are all trained mechanics.

Seems like I have no power to the heater..
could be the connection at the blower motor. inspect the contacts and post your findings. the blower motor may be going bad (high resistance) this may burn up the terminals at the connection or inside the motor itself
I need to change pistons
this is a very big job and u need to get a repair manual. u can buy one from auto parts store. u will also need some special tools to do the job. u will need to mike the cylinders to make sure that they r not worn out to big, some tools u will need r ridge reamer, ring grove cleaner, a ring compress to name a few.
How do i change pistons
best way is to pull the engine and put it in an engine stand. It is a long job requiring more that back yard mechanic knowledge . If you do not have a workshop manual the I suggest you get one .
Transmission
I do not really know, but try checking that the transmission is not overflowed or low on transmission fluid.
Crank sensor
When vehicle reaches a high temperature and cuts out pore water on the crank sensor. Once crank sensor is cooled down , vehicle will be able to start.
98 accent clutch noise
That may be the clutch release bearing-a part of the clutch assembly inside the bell housing. If that is what is humming, it will be okay for awhile-maybe a few months. Eventually the noise will get louder and become a screeching, drive-you-crazy noise ! Then it will be time to replace it-a small donut-looking device with a sealed bearing inside it. Apparently the bearing is starting to fail. Have a mechanic listen to it to verify if it is the release bearing.
Car will not start
Try running a wire from the little terminal of the starter motor to the Positive on the battery , Disconnect the little wire thats on there first.No need to turn the key on as we are bypassing this.This should cause the starter to turn.Make sure that if its a manual that its in Neutral.
If the starter motor turns then the problem is either the relay or the ignition switch.Or if its an automatic Transmission it could be the inhibitor switch .
Hope this helps
Cheers

Knocking noise
Only when turning? One or both of your front axle CV joints is worn. Figure that both are. With these you are usually better to have an exchange front axle assembly fitted both sides. Cost in the USA about $600 NOT at a dealer.
