Reasons for Ignition Coil Failure in Your Jaguar

Every vehicle has parts that break down over time due to wear and tear, even a luxury car like a Jaguar. While that is true, there could be other underlying causes to your car trouble. There are several reasons your ignition coil could fail and cause issues. It is important that you know what it is, why it is important, the signs of a failing ignition coil, and the reasons it may be malfunctioning so you can get the issue fixed as soon as possible.

What is an Ignition Coil?

An ignition coil is an induction coil that amps up the voltage of your battery and sends the current to the spark plugs to ignite the fuel properly. Without it, your Jaguar can’t properly accelerate and your gas mileage will go down considerably. The ignition coil improves every aspect of your driving experience and keeps the car running smoothly.

Warning Signs of a Failing Ignition Coil

If you notice any of these things happening, your ignition coil could be malfunctioning or failing entirely.

You may notice that your Jaguar is backfiring and black smoke is coming from the exhaust pipe. This is because there is fuel left in the combustion chamber of the vehicle that is escaping in a way that isn’t productive.

Less vehicle mileage will occur, as the fuel isn’t properly ignited and your engine isn’t given as much power as it normally would have.

Your engine may misfire and make a coughing or wheezing This can lead to your car jerking or vibrating when you attempt to drive at higher speeds or stop quickly. As you can imagine, this is a more dangerous side effect of a failing ignition coil.

Your “Check Engine light” will come on.

It is hard for you to start up the engine. Since the ignition coil gives your vehicle extra voltage, the absence of one will provide too little power for you to drive.

You will not be able to accelerate your speed as much as you’re used to. Again, low voltage = less power.

Reasons for the Malfunction or Failure of an Ignition Coil

All of these negative symptoms showing up that affect your driving performance are only the tip of the iceberg. There are a few root causes of the issue that can even become dangerous over time. To prevent your Jaguar from being seriously damaged, you need to get to the real problem and have it fixed. This may include:

Incorrect voltage when it comes to the battery of your car. If the voltage is too high or too low, your ignition coil will not be able to properly do its job and will wear out. You need to have your battery replaced with one that possesses a compatible voltage.

Bad spark plugs. If one of your spark plug ignition cables is faulty, it causes your ignition coil to put out far too much power with no result. This wears it down prematurely and causes it to fail entirely. Have them replaced when they need to be.

The valves in your vehicle from various parts may lose their sealing power, causing your car to leak oil. This oil can gunk up your coil and your cables, preventing them from conducting electricity properly.

Water damage. Water + electrical parts = disaster. This is true of just about any electronic device you have. The same can be said of your car parts.

Any of these require a trip to an auto shop. You can’t be sure you can fix them on your own unless you are a trained and qualified mechanic yourself. After you get your ignition coil replaced and your various other issues patched up, you will need to do regular preventative maintenance to keep it from happening again.

Preventative Maintenance for Your Jaguar

This one is fairly simple. Start having your car taken for regular inspection and small repair at a professional auto shop. There isn’t much else you can do; taking care of your Jaguar is essential. It is better to be safe than sorry.

In the meantime, where do you go to have your ignition coil replaced and your various leaks or faulty cables fixed?
