I don't have a pic but it should be right below the water pump. I got the same code a few weeks ago. All it needed was to be tightend, it came loose.

Your crank sensor (CKP) was loose, the magnetic pick up was too far from the timing belt gear or the crankshaft reluctor, this increased the air gap which decreased the amplitude of the electronic signal back to the ECU setting your code.

The first test is an ohm test (I hate em) of the pick up (sensor) to see if it is in specs, out of specs, go pick up a new one, ohm it out at the store to make sure its in spec and change it, there also could be a broken wire or a shorted wire. Make sure it goes all the way into its mount so that air gap is proper. I prefer an oscilloscope trace of the sensor pattern to see it the gear reluctor is broken, if the signal is weak or nonexistant, or completely missing, broken wire or open or shorted sensor, I would test it at the computer, does your car run.

What is your exact code and what is the definition.

Since you didnt give all the info on your car ('99?) it could be inside the distributor for an older car.
