No special tools needed just basic hand toolsA misfire fro. On your DIN test machine or on your workbench hold the lead that is attached to the ignition coil.
This voltage is distributed by the module to the 3 ignition coils sitting on top of it and to the crankshaft position sensor assembly.
How to test coil pack. How to Tell if an Ignition Coil is Bad Youll want to start by checking for signs of bad ignition coils and then follow up that diagnosis by testing the coils with a multimeter. Ignition coils take energy from the battery usually 12 volts and convert it to a high enough voltage 50000 volts or more to create a spark. You can also test an ignition coil with a spark tester.
The tool is installed inline with the ignition coil to determine if the coil is producing a spark. If all of the ignition coils arent delivering spark the issue is likely with the control side primary side of the ignition system rather than a single ignition coil. An absence of spark from just ONE ignition coil points to a bad coil.
How to Diagnose Faulty Coil Pack without using a computer or OBD2 scan tools Check Engine Light. No special tools needed just basic hand toolsA misfire fro. How to Test a Faulty Coil Pack Step 1.
Open the hood of your vehicle. Disconnect the negative battery cable. Locate your vehicles coil pack by tracing.
Disconnect the spark plug wires from the coil pack one at a time. Label each wire to keep track of the correct. You need to use ohm meter to test the coil pack for continuity.
Make sure you have the approximate ohm values for the coil pack. To find this information research your cars engine on the Internet or purchase a Chiltons or Haynes manual to find out what the mega ohms reading on the coil pack should be. How to Check Coil Packs With a Voltage Meter Step 1.
Park your car in a safe place and open the hood. Locate the coil pack in your engine by following the spark plug wires from the spark plugs. Unplug the spark plug wires from the coil and label the wires if.
You can usually test your ignition coils by plugging a diagnostic machine like an ODB2 scanner into the port underneath the dashboard and turning it on. On most scanners a code P0352 indicates that your coils arent working correctly. If you dont have a diagnostic tool you can remove the coils to test them instead.
Your vehicle does not pass the emissions test. Basic Working Theory Of The 38L Ignition Coil Pack. In a nutshell when you turn the key to crank and start your car.
12 Volts flow into the ignition control module. This voltage is distributed by the module to the 3 ignition coils sitting on top of it and to the crankshaft position sensor assembly. Watch for a spark in the tester window as you pull the starter cord.
To test the operation of both the ignition coil and the spark plug connect the tester between the spark plug boot and the spark plug. Then start the engine and watch the tester window. A spark plug misfire will immediately be evident in the tester window.
There are two other ignition system tutorials that might be of interest. If you need to test the 19L20L 4 cylinder Ford coil packs click here. How To Test FORD 4 Cylinder Coil Packs.

The easiest way to tell ignition coil pack symptoms is scanning the error code. So by seeing the error code you can check the engine light and figure out what is the coil pack problem. First you need to locate the ignition coils.
Look near or on the engine for the coil pack. Disconnect the mounting bolts that are stabilizing the ignition coils and then remove each coil from the engine area. Test the Primary Winding.
Switch signal test Examine whether your ford coil pack is getting 12 volts when your engine is on you can only examine this through the use of a multimeter. Furthermore you should verify that it gets its signal from your control module through the use of LED light and after that remove your ford coil pack from the connector. Check to make sure the spring is releasing gas.
The next step to how to test ignition coil problems is to locate the ignition coil. On your DIN test machine or on your workbench hold the lead that is attached to the ignition coil. It should be at the end of the coil.
This will help you get a reading of ignition coil temperature. The check engine light is one of the most common symptoms of bad Coil Packs. More often than not your engines computer will be able to detect bad Coil Packs in your Aveo.
There are several misfire related trouble codes. P0300 this trouble code indicates that there is a random misfire. Ignition coil pack resistance checking is a popular approach because you will need a digital multimeter to confirm the coils resistance readings in ohms.
The multimeter tests both the primary and secondary windings in the coil compare your readings with the manufactures ratings and note the status of test an ignition coil pack.
