This article will help you to test the crankshaft position sensor on the Chrysler, Dodge, Eagle, Plymouth, 2.0L (SOHC and DOHC) and 2.4L (DOHC) 4 cylinder equipped cars and mini-vans.
This article covers vehicles from Chrysler, Dodge, Eagle, Mitsubishi and Plymouth. To see if this article applies to your specific vehicle, look for the box (on the column on the right) titled ‘Applies To:’, and click on the ‘next >>’ link to scroll.
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.
Here are the contents of this article at a quick glance:
You can find this tutorial in Spanish here: Cómo Probar el Sensor de la Posición del Cigüeñal (Chrysler 2.0L, 2.4L) (at: autotecnico-online.com).
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.
Tools You'll Need to test the crank sensor on your car (or mini-van):
As you see, the tools you'll need won't break the bank and more than likely you already own most of them.
“This planet has - or rather had - a problem, which was this: most of the people living
on it were unhappy for pretty much of the time. Many solutions were
suggested for this problem, but most of these were largely concerned
with the movement of small green pieces of paper, which was odd
because on the whole it wasn't the small green
pieces of paper that were unhappy!”
