Symptoms of a Faulty Ignition Coil in your Vehicle

SYMPTOMS OF A FAULTY IGNITION COIL IN YOUR VEHICLE

An internal combustion engine runs due to the proper synchronization of fuel, air and electricity.

The ignition coil works to provide the required electricity to the engine.

The engine coils must be in good condition and performing for your vehicle's engine to run efficiently.

Generally, the ignition coils consist of 3 parts-

A primary circuit A secondary circuit An iron core

SYMPTOMS OF A FAULTY IGNITION COIL

The ignition coil is responsible for generating the engine spark which starts your vehicle.

So, any problems will affect engine performance issues.

Here are the common symptoms of a faulty ignition coil in your vehicle.

CHECK ENGINE LIGHT GETS ILLUMINATED

In your car, a faulty ignition coil can illuminate the check engine light.

If you have an OBD-II diagnostic scanner, you can see the error code.

Depending on the model, an ineffective ignition coil may register a different code for the problem.

ENGINE STARTS TO MISFIRE

When the ignition coil stops working properly, your vehicle’s engine will likely misfire.

A misfiring engine results in a jerking or sputtering ride when you are moving at normal speeds.

When you stop, a misfire from a faulty ignition coil may cause your vehicle to run roughly and vibrate.

VERY POOR FUEL ECONOMY

With less spark energy the combustion process there will be a noticeable decline in fuel economy.

Ignition coils can either fail completely or fail intermittently.

Vehicles with bad ignition coils often run roughly and you may also experience a drop in power.

WHY DOES THE IGNITION COIL FAIL?

In most cases, the ignition coils are durable components.

Ignition coils tend to fail because of either bad spark plugs or plug wires.

Also, engine heat and vibrations can cause damage to ignition coils.
