This bad boy is located in the distributor and also testing that is no hard since it have the right to be tested through a basic multimeter.

With the aid of this turorial you"ll have the ability to easily discover out if it"s defective or not.

NOTE: The camshaft position sensor is additionally known as the distributor pickup coil.

APPLIES TO: This tutorial applies to the following vehicles because they usage the specific same camshaft place (CMP) sensor:

3.9L V6 dodge Dakota: 1998, 1999, 2000, 2001, 2002, 2003.3.9L V6 evade Durango: 1998, 1999.

Symptoms the A negative Camshaft position (CMP) Sensor

The fuel injection computer uses the camshaft position (CMP) sensor signal in combination with the crankshaft position (CKP) sensor signal to start injecting fuel and also to begin activating the ignition coil (among number of things).

Since the 1998-2003 3.9L dodge Dakota (and 1998-1999 3.9L dodge Durango) space equipped v OBD II, once the camshaft place sensor fails, the fuel injection computer system will normally (but not always) collection a diagnostic problem code. You might see the complying with trouble code stored in the fuel injection computer"s memory:

P0340: No Camshaft Signal at PCM (1996-1997 OBD II system).

If you have a password reader or a scan tool, examine for codes. To test the yes, really camshaft place sensor, a scan device is not required.

What I can assure friend is that when the camshaft position sensor fails, climate engine in your Dodge Dakota (or Durango) is no gonna" start because of a lack of spark and a absence of fuel injection.

Circuit explanation Of The Camshaft position Sensor

The camshaft position sensor has 3 wires coming out of its electric connector. One wire offers power. One wire provides Ground. And also the various other wire tote the CMP signal to the fuel injection computer.

In the tables listed below you"ll uncover a quick description of each of the 3 wires:

Where come Buy The Camshaft position Sensor

Checkout the complying with links and comparison shop the camshaft position sensor for your 1998, 1999, 2000, 2001, 2002, 2003 3.9L dodge Dakota and also 1998, 1999 3.9L dodge Durango:


TEST 1: testing The Camshaft place Signal

To start off our camshaft position (CMP) sensor diagnostic, we"re gonna" verify the the CMP sensor is creating an ON/OFF voltage signal together we crank the engine.

ON is when the CMP signal reads 5 Volts DC and also OFF is when it reads 0 Volts DC (on the multimeter).

If the camshaft place sensor is functioning correctly, you"re gonna" view the multimeter switching in between 5 Volt and also 0 Volts as you crank the engine.

If the camshaft position sensor is bad, it"s gonna" remain stuck creating a single voltage worth (usually 0 Volts) together you crank the engine.

We"ll achieve this through connecting our multimeter to the tan through yellow stripe (TAN/YEL) cable of the CMP sensor"s engine wiring harness connector. In the photograph above, the TAN/YEL cable is determined with the number 3.

Before we start let me call you that your 3.9L evade Dakota come equipped through a camshaft position sensor and also a crankshaft position sensor. The camshaft position sensor is situated in the distributor and the crankshaft place sensor is bolted onto the transmission bell housing. Both that the connectors space in the same ar so take treatment to test the exactly connector.

IMPORTANT: The camshaft place sensor must be connected to that engine exploit connector because that this test to work. You"ll need to connect your multimeter test cause a earlier probe or a cable piercing probe to read the CMP signal. You have the right to see an instance of a cable piercing probe here: Wire Piercing Probe testimonial (Power Probe PWPPPPP01).

NOTE: Don"t have a multimeter or need to upgrade yours? examine out mine recommendation: Buying A Digital Multimeter for Automotive Diagnostic Testing.

These are the test steps:


Disconnect the ignition coil native its electrical connector. This is crucial safety precaution!NOTE: Don"t eliminate the distributor lid from the distributor. The distributor cap need to be in place to organize down the camshaft position sensor.


With the red multimeter check lead, probe the tan with yellow strip (TAN/YEL) wire of the camer sensor connector.NOTE: The camshaft place sensor should remain associated to the engine wiring exploit connector to be able to read that is signal.


Have your helper crank the engine because that a few seconds once the multimeter check lead relationships are set up.


Your multimeter must see the voltage switch in between 5 Volts and 0 Volts DC as the engine is cranking.

Let"s study your CMP signal test result:

CASE 1: The multimeter review the shown ON/OFF DC voltage. This is the correct and also expected test an outcome and speak you that the camshaft position sensor is work correctly.

Since the camshaft position sensor IS no defective, something rather is bring about your 3.9L V6 Dakota to not start.

CASE 2: The multimeter go NOT check out the suggested ON/OFF DC voltage. This test result usually way that the camshaft place sensor is defective.

Before you change it, make certain it"s gaining power and also Ground. Because that the following test go to: test 2: Making sure The CMP Sensor has Power.
