The code is related to the crankshaft sensor, but the sensor should have caused a sound as you described. Basically, the code indicates there is no signal from the sensor when the engine is being cranked. However, that is what I need to verify with you. Does the engine now crank normally? Have you tried deleting the code to see if it returns?
I'm asking simply because the crank sensor on this vehicle is a big job. It requires the timing belt to be removed and replaced. I would be happy to provide the directions, but want to be sure the sensor is bad before doing all that work for nothing.
First, I want you to remove the MFI relay and check for corrosion or anything that can cause a weak connection. If you look at the two pics below, you will see how power runs through the relay from the crank sensor. Pic 2 shows relay location (under hood).
If possible, switch that relay with a different one in the box that has the same part number, clear the code, and see if it returns.
If you want, here is a link that explains how to test a relay:
Let me know. Also, if it is still making that noise, see if you can record it and upload it for me to hear.
Take care and let me know what you find or if you have other questions.
