there are 2 pieces to the crankshaft sensor...one is a little round thing that is mounted under the valve cover on the driver side. The other part plugs into this and the cable runs down under the other side of the engine. The sensor is inside the timing belt cover.
i had your problem a month ago and had the little round part replaced and that worked for me.
Probably something in the wiring harness or the engine computer.
A mechanic would watch the data stream from the O2 sensors to troubleshoot. You should also have trouble codes for the sensor in question.
My online Sonata manual shows these possibilities, but does not identify which applies specifically to 2000 Sonata. Also, when you talk to the dealership parts counter, you'll need to know whether your 2000 Sonata is (a) 4-cylinder 2.4L MFI DOHC engine, or (b) 6-cylinder 2.5L MFI DOHC engine. Its easy to tell - just count your spark plug wires.

The camshaft position sensor is located on the engine near the timing belt cover and under the upper radiator hose.

The crankshaft position sensor is located at the front of the engine near the timing belt.

Under the hood, there is a fuse block. I believe it is on the driver's side of your vehicle. Open that box, and pull the "ECU" fuse. Leave the fuse out for at least 5 minutes. Put the fuse back in, start the car, and let it idle for at least another 5 minutes. Do not drive the car, touch the gas, or even look at the gas pedal for these 5 minutes, as the ECU is remapping itself. This will properly reset the ecu and clear the codes. After this you may drive the car.
you could have a break in what is called the keep alive memory power to the computer. each time you shut off the car the computer resets itself. the trick is to put enough miles on the car in one day and not shut off the ign untill you get the test done. or find the break in the keep alive memory wire to the computer.
good luck chris
CA you can take the car to a referree and get a one time waiver if you have spent a minimum of $450 on repairs not including smog fees. Gives you two years to get it fixed.
