What are the signs of ignition coil damage?

The Ignition coil must be in good condition and running properly for the vehicle's engine to run properly.

Therefore, if your engine is not performing as usual, there may be a failure of the ignition coil.

Most cars on the road today have internal combustion engines, which require fuel, air and electricity to run. In modern vehicles, Ignition coils play an important role in providing electrical components for the equation.

Therefore, if your ignition coil is faulty, your engine will not run properly. Worse, it could stall altogether.

What does the ignition coil do?

To generate power, your vehicle's engine needs the right mix of gasoline and oxygen. Then, it needs a spark to ignite the mixture. Car batteries are only about 12 volts.

This is well below the thousands of volts needed to produce the right type of spark. The ignition coil converts the battery voltage to a level that allows the Spark plug to operate.

Where is the ignition coil in the vehicle?

The location of a vehicle's ignition coil depends on its make and model. Some vehicles have an ignition coil in each Spark Plug at the top of the engine block. Others have only one coil to ignite each spark plug in the engine.



Evidence of damage to the ignition coil

1. ILLUMINATED CHECK ENGINE LIGHT

For most modern vehicles, a faulty ignition coil is sufficient to turn on the engine light for inspection.

2. MISFIRING ENGINE

If the ignition coil is not working properly, your engine may catch fire. A misfire engine can cause a jolting or sputtering sensation when you are traveling at normal speed. When you stop, damage to the ignition coil may cause the vehicle to catch fire, causing instability, vibration, or shaking.

3. WORSENING GAS MILEAGE

Ignition coils may fail completely or intermittently. This means that your coil may deteriorate over time. So even if your vehicle appears to be performing normally, you should pay attention to whether gas mileage deteriorates.

4. DIMINISHED POWER


Vehicles with poor ignition coils often drive rough. This means that you may feel a rough sensation or sound when your vehicle is idling. Your vehicle may also experience a power drop.

As a result, a poor ignition coil can cause it to accelerate more slowly. The vehicle may even stall.

How do I replace a damaged ignition coil?

Many ignition coils have a plug and play design and are easy to replace. Some coils are still hard to reach. However, if you do the job yourself, you only pay the cost of the parts. If you have a mechanic to do the job, you have to pay for the labor.
