Wow, Unless I'm missing something, that seems WAY too high to replace the sensor. I know things are really stuffed into the engine bay, but that still seems like a lot. This is the same car as a Dodge Stealth, and I think I would have heard about it if that sensor was uncommonly difficult to replace.
As for tests, you will need a hand-held computer called a scanner that plugs into the wiring harness and can talk back and forth with the Engine Computer. The dealer's equipment can do that, but so can most aftermarket equipment that independent mechanics use. I use two versions of Chrysler computers. They will state "present" for the crankshaft position sensor and the camshaft position sensor when those signals are arriving at the computer during engine cranking. When a signal is missing, there are only three wires to test for the crankshaft sensor. With the ignition switch turned on, one should have either 5.0 or 8.0 volts, (I can't remember), the ground wire will have around 0.2 volts, and the signal wire will pulse between 0 and 5 volts while a helper cranks the engine. That signal wire can be hard to read with a digital voltmeter because it bounces around too much.
As a side note, most shops use a "flat rate" guidebook to quote labor times so they are in line with any other shop. I'm going to try to find one here, but if you can sweet talk the dealership repair department people or some other mechanic to show you the suggested time to replace the sensor, you will get an idea of what the repair should cost. Most shops are charging close to 100 dollars per hour now, (and if you could see the list of all their expenses, you'd wonder how they could afford to stay in business), and a TYPICAL crankshaft position sensor should cost somewhere between 50 to 100 dollars. That would mean they expect it to take them four or five hours to do the work. I don't want to second guess an expert without more information, but that does seem really high.
I had five laptop computers puke out on me in the last three months. With them, I could access the Chrysler web site and look at their flat rate guide, but I'm down to just this ten-year-old ultra-reliable tank of a computer, and something won't let me into that site.
