I have a '99 5S-FE. Mine has a crank position sensor.
I can see it easily right now since I've got the crankshaft pulley off (I'm in the middle of a timing belt change). It would be tough to see if the crankshaft pulley were on, as it sits behind the pulley at the bottom front of the engine. Maybe you could see it with a mirror or by getting directly under the crankshaft pulley and looking up into the space between the pulley and the front of the engine.
Also, mine has an electrical connector for the crank sensor that is on a bracket just above the A/C compressor and in front of the upper timing belt cover. A wire runs from this connector down the front of the engine and goes to the crank sensor. There is a pretty good pic of this connector and wire on the following thread

Look for the 11th picture down.
I hope this helps!
