How to Diagnose a Bad Ignition Coil in a Car

Proper functioning of an ignition coil is absolutely essential for a vehicleu2019s engine to perform optimally. If the ignition coil fails, the car will run badly or it will probably stall in the mid of nowhere. Since an ignition coil can fail intermittently, hence, knowing the symptoms of a bad ignition coil is imperative. An ignition coil can be conventional, distributorless, or electronic. No matter, what kind of coil it is, you have to be knowledgeable about the symptoms of its failing so that you can replace the coil timely and prevent the engine performance from getting reduced.

  1. HOW TO DIAGNOSE A BAD IGNITION COIL IN A CAR?

  2. The spark plug needs a huge amount of electrical energy to generate the spark required to ignite the combustion chamber of the engine.

  3. The primary function of an ignition coil is to convert 12V current into 20,000-40,000V of current for the spark plug, due to which it is also known as a compact transformer.

  4. A car engine with a defective spark plug or faulty ignition coil might fail to start.

  5. So, signs which show that the ignition coil has some defects should not be ignored.

  6. Such problems need immediate attention to keep the engine in working order.

  7. DIAGNOSING A BAD IGNITION COIL

  8. DIFFICULT TO START THE ENGINE As mentioned earlier, ignition coil is an integral part of the ignition system of a car.

  9. Spark plug with a defective ignition coil fails to generate the spark required for ignition as a result of which the engine fails to start.

  10. So, such problems need to be repaired immediately.

  11. ENGINE MISFIRES AND BACKFIRES Timing of spark generation by the spark plug is an important aspect of internal combustion.

  12. If one of the cylinders fires incorrectly due to an abnormal ignition coil, then it could cause engine misfiring.

  13. Besides, issues in the fuel injection system and spark plug could also be responsible for the engine misfiring.

  14. Problems in the ignition coil could also be responsible for engine backfiring.

  15. FUEL ECONOMY DECLINES If the fuel economy of a car declines suddenly, then it indicates that certain components of the engine are not working properly.

  16. Issues in the ignition coil of a car does affect the fuel economy of a car in a very adverse way.

  17. CHECK ENGINE LIGHT ILLUMINATES The engine control module or ECM monitors the performance of different components of the internal combustion engine.

  18. If the ECM found any kinds of faults in the ignition system, then it would turn on the check engine light.

  19. THE FINAL WORDS

  20. Ignition coil is an important part of the ignition system of a car.

  21. Problems in such an important part could jeopardize the engine.

  22. So, indications of a defective ignition coil should not be ignored and efforts should be made to fix the problems in time.
