One of the most common troubleshooting tasks for car mechanics is testing the spark plug wires. But what about when something goes wrong with the coil? In this blog post, we will show you how to test 4 pin ignition coil with multimeter. This simple test can help you diagnose and solve many issues with your car’s electrical system.
What is a 4 Pin Ignition Coil?
A 4 pin ignition coil is a type of coil used in automotive engines. It consists of four terminals – two each for the hot (+) and cold (-) leads. When the correct voltage is applied to the coil, it will cause a spark that ignites the mixture in the engine. A failed 4 pin coil will cause an engine not to start.
How To Test A 4 Pin Ignition Coil
Testing a 4-pin ignition coil can be done with a multimeter. The test will measure the resistance between theNegative and Positive leads on the coil. A reading of 0 ohms indicates that the coil is good, while a reading of 3 ohms or more indicates that the coil is bad and must be replaced.
What to do if the Test Shows An Error Code
If you are having trouble with your car’s pin ignition coil, there are a few things you can do to test it. First, check the fuses for the coil. If the coil is not getting power from the fusebox, then it may be because of a blown fuse. Next, try swapping out the coil with another one. Finally, if all else fails, you can take your car in for repair.

How to Repair or Replace A 4 Pin Ignition Coil
A faulty 4 pin ignition coil can cause your car to not start. If your car won’t start, the first step is to check the fuse panel for blown fuses. If there are no blown fuses, then you will need to replace the ignition coil. The steps for replacing the ignition coil are as follows:
1) Disconnect the negative battery cable.
2) Remove the cover pad on the engine block near where the spark plugs are located. On some engines, there may be a Torx screw in this area that needs to be removed before you can remove the cover. Note: Some engines have a computer module that must also be removed in order to access and replace the ignition coil.
3) Locate and remove four screws that hold down the ignition coil box.
4) Once screws are removed, carefully pull out old ignition coil assembly. Be sure to note which wires go to which terminals on new replacement coil assembly. You will also need to connect these same wires back up during installation.
5) Install new ignition coil assembly by reversing steps 4-5 above. Be sure connection between wires and terminals is correct before reinstalling cover pad and screws!
