Understanding Ignition Coils and Resistance
1. What are an ignition coil and its function?
An ignition coil is a type of transformer that takes the low voltage from the vehicle’s battery and transforms it into a high voltage that’s necessary to ignite the fuel and start the engine. The high voltage is then sent to the spark plugs, which ignite the fuel and air mixture in the engine cylinders.
2. The role of resistance in ignition coils
Resistance plays a crucial role in the functioning of ignition coils. The resistance determines the amount of voltage that’s required to create a spark at the spark plugs. The higher the resistance, the higher the voltage required, and vice versa.
The correct resistance specifications are critical to ensure that the ignition coils can produce the right amount of voltage to ignite the fuel and start the engine.
3. Types of ignition coils and their specifications
There are several types of ignition coils, including traditional coils, coil-on-plug (COP) coils, and coil packs. The specifications for each type of ignition coil vary, and it’s essential to use the correct specifications for your vehicle’s ignition system.

Common Causes of Ignition Coil Failure
Overheating of ignition coils
Overheating is one of the most common causes of ignition coil failure. When ignition coils get too hot, they can become damaged, and result in misfires and decreased performance. Overheating can be caused by several factors,
Including excessive voltage, overloading, and lack of proper cooling. According to a study, high temperatures can cause ignition coils to lose their magnetic properties, leading to reduced performance and eventual failure.
Excessive voltage
Excessive voltage can also cause ignition coil failure. When the voltage supplied to the ignition coils is too high, it can result in overheating and damage to the coils. This can occur due to issues with the vehicle’s electrical system, such as a malfunctioning alternator or a bad battery.
Wiring problems
Wiring problems can also cause ignition coil failure. Damaged or corroded wiring can lead to a loss of power or grounding issues, which can result in ignition coil failure. It’s essential to inspect the wiring to your ignition coils regularly and replace any damaged or corroded wiring promptly.
How to Test Ignition Coil Resistance
Tools and equipment needed
To test ignition coil resistance, you’ll need a multimeter with an ohmmeter setting. A multimeter is a device that measures electrical current, voltage, and resistance.
Steps to test ignition coil resistance
To test ignition coil resistance, follow these steps:
- Locate the ignition coils on your vehicle
- Turn off the engine and disconnect the battery
- Set your multimeter to the ohmmeter setting
- Touch one probe of the multimeter to the positive terminal of the ignition coil and the other probe to the negative terminal
- Record the resistance reading
- Repeat the process for each ignition coil
Interpreting the test results
The resistance readings for your ignition coils should fall within the specified range for your vehicle. If the readings are outside of the specified range, it could indicate a problem with the ignition coils, and they may need to be replaced.
It’s essential to consult your vehicle’s owner’s manual or a reputable mechanic for the correct resistance specifications for your vehicle.
Maintenance and Upkeep of Ignition Coils
Few Tips for maintaining ignition coils
Regular maintenance and upkeep can help extend the lifespan of your vehicle’s ignition coils and prevent failure. Some tips for maintaining ignition coils include:
- Regularly inspect the wiring to the ignition coils
- Keep the engine and ignition coils cool
- Use the correct ignition coil specifications when replacing ignition coils
- Keep the engine well-tuned and maintained
Signs of ignition coil failure and when to replace them
Signs of ignition coil failure can include misfires, reduced fuel efficiency, and engine damage. If you notice any of these symptoms, it’s essential to have your ignition coils inspected promptly and replaced if necessary.
Regular maintenance and upkeep can also help identify potential issues before they lead to ignition coil failure.
Importance of regular maintenance and upkeep
Regular maintenance and upkeep are crucial for the longevity and performance of your vehicle’s ignition coils. Ignition coils that receive proper maintenance and upkeep are less likely to fail and result in costly repairs.
