Now, since the crankshaft position (CKP) sensor can not be tested by a simple resistance test (multimeter in Ohms mode) off of the car, I'm gonna' show you how to test it dynamically (in action) and on the car. This is a simple multimeter test done in Volts DC mode and I'll walk you thru' the whole thing step by step.

When the crankshaft position sensor goes BAD on your Chrysler 2.0L, 2.4L... the most obvious symptoms will be that your car is not gonna' start. It will crank but not start.
Here are some more specific symptoms of a BAD crank sensor:
The two most important symptoms to look for are no spark from all of the spark plug wires and no fuel injector pulses from all of the fuel injector connectors (as tested by a noid light).
If you have spark, even if it's just from one spark plug wire or fuel injector pulses... the crank sensor is not BAD.
You don't need any expensive tools to test the crank sensor on your 2.0L, 2.4L engine. As a matter of fact, you don't even need a scan tool to test it.
