Nowadays, everyone household will own a car. With the increasing number of cars, there are more and more new drivers. However, many drivers do not have deep understanding of the technical issues revolving around their vehicle.
As such, many car owners are unable to do a basic detection, troubleshooting, etc. This is why at RepairHub, we hope to pass on a few tips to help you become more aware of your vehicle issues.
In this article, we will move on from basic filters to understanding your very own IGNITION COILS.
Firstly, lets understand, what exactly does the ignition coil do? An ignition coil, also known as a spark coil, is an induction coil in your car’s ignition system which transforms the battery’s low voltage into thousands of volts which are needed to create an electric spark in the spark plugs to ignite the fuel. Ignition coils can have either an internal resistor or an external resistor or resistor wire, which serves the purpose of limiting the current flowing into the coil from the car’s battery.
Moving on.... What exactly are the symptoms of a faulty ignition coil???
In most cars, a failing ignition coil or coil pack will also cause a check engine light. This is caused either by your car’s computer detecting misfires, or detecting an issue with the ignition coil signal or circuit, such as when a coil shorts or burns out. However, keep in mind that a check engine light may be caused by a wide variety of other issues, so having the computer trouble codes read by a professional is highly recommended.
Other issues include:
1) The corresponding cylinder of the ignition coil becomes faulty, causing the idling speed and the throttle to not increase in any speed.
2) Leaking ignition coils. and you feel extreme shaking or vibration of the vehicle when idling.
3) Extreme vibration of the engine, similar to those of a truck, and if the vehicle is accelerated, you may feel that it is unable to increase in speeds.
So what causes an FAULTY IGNITION Coil?
The main cause is usually due to the breakdown of the insulator of the ignition coil.
Otherwise.... it may be one of the following reasons....
1. The short circuit of the spark plug will directly cause the ignition coil current to increase and short circuit;
2, spark plug open circuit (more carbon), will cause the ignition coil load to increase, long-term overload work and failure;
3. Short circuit of high voltage line to ground (ironing) will cause the ignition coil current to increase and short circuit;
4. When the high-voltage line is broken, the high voltage generated by the ignition coil cannot be released, and the voltage accumulation will discharge to the ground and cause a failure;
5, the power supply voltage is high, it will cause the primary circuit current is too large, abnormal heat, and the ignition coil burst
In conclusion, it is always good to constantly monitor your vehicle for issues and diagnostics. Let us know what other issues you will like to know in the comments below!
