The ignition coil is a central element in the vehicle's ignition system that ensures efficient combustion in the engine. It converts the battery voltage into the high voltage necessary to produce the spark at the spark plugs. But how do you recognize? defective ignition coils, and what symptoms indicate this? Our article serves as a small guide to help you Signs of a defective ignition coil to find and possible Engine problems and expensive repairs to avoid.
Detect defective ignition coils
- First sign: One of the most common symptoms of a defective ignition coil is a jerky and rough running engine. If the ignition coil is not working properly, it cannot provide enough voltage, resulting in incomplete combustion. This often manifests itself in a noticeable loss of power when accelerating.
- Second sign: Another common symptom are teething problems. A faulty ignition coil can result in the engine not receiving the energy it needs to start. Such problems are a clear indication of possible defects in the ignition system, especially on cold days.
- Third sign: An elevated one Consumption can also indicate problems with the ignition coil. When combustion is inefficient, the engine requires more fuel to produce the same power. This ultimately leads to an increase in consumption.
- Fourth sign: Modern vehicles are equipped with an on-board computer that monitors various vehicle systems. A defective ignition coil is often indicated by the lighting up Engine light signaled. With help of a diagnostic device it can be read whether the error message is in the context of the ignition coil.
Diagnosis and maintenance
If you suspect a defective ignition coil, you should contact one immediately professional diagnosis be carried out in a specialist workshop. A specialist can use special diagnostic tools to not only find the faulty ignition coil, but also other components Check the ignition system. Regular Maintenance and inspections are essential to ensure the longevity and performance of the engine.
Conclusion
- Early detection of a defective ignition coil can help Engine damage and costly repairs to avoid. Pay attention to the symptoms mentioned and do not hesitate to go to a specialist workshop if there are any irregularities. Regular vehicle maintenance is the best way to ensure that all components, including the ignition coils, are working properly.
these are possible further symptoms
- Decreased performance: If the engine isn't performing as expected or the vehicle isn't responding as it should, it could be due to a faulty ignition coil.
- Uncommon noises: Crackling or popping noises from the engine compartment may indicate ignition problems.
- Rough engine running: Another common symptom of a bad ignition coil is rough or uneven engine running.
- Misfires: Engine misfiring is a clear sign that the ignition system, particularly the ignition coils, should be checked.
- Dropouts under load: Especially under load (e.g. when accelerating), misfires can indicate that the ignition coils are not working correctly.
