Symptoms of a defective or defective ignition coil
The ignition coil is an electronic engine management component that is part of the vehicle's ignition system. The ignition coil acts as an induction coil, transforming the 12 volt voltage of the vehicle into the thousands of volts needed to jump the spark plug gap and ignite the engine mixture. Some ignition systems use one coil to provide spark for all cylinders, but most modern designs use a separate coil for each cylinder.
Since the ignition coil is the component responsible for generating engine sparks, any problems with the ignition coil can quickly lead to engine performance problems. A faulty ignition coil usually causes some symptoms that alert the driver of a potential problem.
1. Engine misfire, severe idle speed, and power loss
One of the most common symptoms associated with ignition coil failure is engine performance problems. Since the ignition coil is one of the most important components of the ignition system, this issue can damage the spark and quickly cause performance issues. If the coil fails, the vehicle can experience fire, rough idle, loss of power and acceleration, and reduced fuel consumption. In some cases, performance issues can even cause the vehicle to stall.
2. Check if the engine light is on
Another symptom of a potential problem with the vehicle ignition coil is that the Check Engine Light is on. A coil failure can cause engine performance problems, especially if there is a fire, the computer will wake up and the check engine light will turn off. If the computer detects a problem in the ignition coil signal or circuit, the check engine indicator will also go out, such as a coil burnout or short circuit. Check engine lights can be caused by various issues, so please create a computer (scan fault code) [https://www.yourmechanic.com/services/check-engine- light-is-on-in-spection] Highly recommended.
3. The car does not start
A faulty ignition coil can also cause a start failure. For vehicles that use a single ignition coil as the spark source for all cylinders, the defective coil affects the operation of the entire engine. In the event of a complete coil failure, the engine will remain sparkless and will not spark or start.
Ignition coil problems are usually easy to spot because they cause symptoms that the driver notices very easily. If you suspect a problem with your vehicle's ignition coil, your Mechanic technician should check your vehicle to determine if the coil needs to be replaced.
