How To Test The Crank Sensor (Chrysler 2.0L, 2.4L)

This tutorial 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.

Symptoms Of A Bad Crank Sensor

When the crankshaft position sensor (crank 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:

  1. The Auto Shutdown Relay does not activate and thus does not provide power to:
    1. The fuel injectors.
    2. The ignition coil pack.
    3. The fuel pump relay and thus the fuel pump.
  2. No spark firing from all of the spark plugs.
  3. Fuel pump does not activate during cranking.
  4. The PCM (Powertrain Control Module = Fuel Injection Computer) does not activate the fuel injectors.

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.

Tools You'll Need To Test The 2.0L, 2.4L Crank Sensor

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):

  1. Multimeter.
    1. You can use a digital multimeter or an analog multimeter although the digital one is the preferred one.
    2. If you don't have a multimeter or need to upgrade yours, check out my recommendation here: Buying A Digital Multimeter For Automotive Diagnostic Testing (at:
  2. Jack
  3. Jack stands
  4. 1/2 inch ratchet wrench and the necessary sockets to turn the crank pulley.

As you see, the tools you'll need won't break the bank and more than likely you already own most of them.
