How to troubleshoot the ignition system in a Mitsubishi?
Disconnect the electrical connector from the coil pack. Use an ohmmeter to check the resistance between the coil pack’s terminals. On a 3.0L engine, measure between terminals 2-3 on Coil A, 1-3 on Coil B and 4-3 on Coil C. Check the measured resistance with the required primary resistance.
What should the spark plug be on a Mitsubishi 2.4L?
It should be between 0.74 to 0.90 ohms on a 2.4L engine and 0.67 to 0.81 ohms on a 3.0L engine. Disconnect the spark plug wires from the coil on a 2.4L engine. Tag the wire so you’ll know where to reconnect them.
What should secondary resistance be on Mitsubishi 3.5L engine?
Secondary resistance should be 9 to 13 kilo-ohms on the 3.5L, 10.29 to 13.92 kilo-ohms on a 3.0L and 20 to 29 kilo-ohms on the rest. A 3.5L engine has more than two terminals at the distributor. Use terminals 1 and 2 when measuring. Don’t touch any metal part of the vehicle while testing the spark plugs and wires.
When does an ignition module need to be replaced?
If the light blinks, the module is good. If the light is blank or constant, the module is bad. Before you attempt to replace the control module, you must rule out other ignition system components. The module is expensive and replacing it is a laborious process. Check the ignition coil for a spark.

When to troubleshoot a Mitsubishi 3.0L V6 engine?
The information in this article is specific to the 1989 3.0l V6 motor. Many aspects of this procedure are common to all 3.0s, but it is advisable to consult a service manual before you troubleshoot your own engine.
What should secondary resistance be on a Mitsubishi?
The desired primary resistance is 0.5 to 0.7 ohms on a 3.5L engine, 0.72 to 0.88 ohms on a 3.0L and 0.9 to 1.2 ohms on the others. Secondary resistance should be 9 to 13 kilo-ohms on the 3.5L, 10.29 to 13.92 kilo-ohms on a 3.0L and 20 to 29 kilo-ohms on the rest. A 3.5L engine has more than two terminals at the distributor.

How do you check ignition resistance on Eclipse?
Probe the terminals at the distributor for other engines. Measure the resistance between the secondary ignition coil terminal on the distributor cap and terminal 1 or 2 of the distributor connector. Compare the measured resistance to the required specifications for your Eclipse’s engine (refer to the Tips for the list).
How do you test the coils on an eclipse?
The way in which you test these coils varies depending on the type of ignition system and the size of the engine. Secure the Eclipse by putting the gear shift in “Park” and applying the emergency brake. Perform the cylinder drop test with the engine idling. Remove a spark plug with insulated pliers for a few seconds.
Do you need scan tool for Mitsubishi ignition coil?
Testing the Coil-On-Plug (COP) ignition coils on your Mitsubishi vehicle (or Chrysler Sebring or Dodge Stratus) doesn’t require any expensive testing equipment or expensive tools. As mentioned at the beginning of the article, you don’t need a scan tool.
How can I tell if my Mitsubishi Sebring ignition coil has gone bad?
You can find this tutorial in Spanish here: Cómo Probar La Bobina De Encendido Y El Sensor De La Posición Del Cigüeñal (2.4L Mitsubishi) (at: autotecnico-online.com ). When one or several ignition coils on your Mitsubishi (or Chrysler Sebring or Dodge Stratus) have gone BAD, you’ll know right away.
Where is the ignition module in a car?
The module receives a signal from a sensor inside the distributor. The signal is then used to fire the ignition coil creating the energy for the spark plugs. The ignition module may be located inside the distributor, on the distributor housing, or mounted to the side of the engine compartment.
How does the ignition work on a Mitsubishi 3.0L V6?
Here’s a little working theory of how the ignition system on your Mitsubishi 3.0L V6 creates the spark needed to get your vehicle started and running. In a nutshell, when the ignition system is working properly and you turn the key to crank and start the engine:
How does the PCM activate the ignition coil?
With both of these signals (and others from other input sensors), the PCM starts to activate the power transistor (ignition control module) to start switching the ignition coil’s primary current (12 Volts) ‘on and off’.
Is the Mitsubishi ignition system the same as Dodge?
To make sure this test tutorial applies to your specific Mitsubishi or Dodge vehicle, please take a look at the application chart at the bottom of this page (mobile device) or on the left column of this page (PC). Contents of this tutorial: Ignition System Basic Working Theory.
How to test the power transistor and ignition coil?
TEST 5: Making Sure The Ignition Coil Is Getting Power. TEST 6: Verifying The Ignition Coil’s Switching Signal. TEST 7: Power Transistor Switching Signal Output. TEST 8: Making Sure The Power Transistor Is Getting Ground. TEST 9: Making Sure The Power Transistor Is Getting An Activation Signal. TEST 10: Crankshaft Position Sensor Is Getting Power.
