The ignition coil is an essential part of your Jaguar car. It is what provides the spark that ignites the fuel-air mixture in your engine, enabling it to run. If you own a Jaguar and it breaks down because of an ignition coil failure, you need to understand what could be causing the problem so you can get your vehicle back on the road as soon as possible. Let’s talk about this issue and how to deal with it.

Functions of the Ignition Coil in Jaguar

The ignition coil consists of a primary and secondary wire that is wound around a common iron core. When the ignition switch is turned on, the primary coil receives power from the battery. This creates a magnetic field that collapses when the current is cut off, generating high voltage in the secondary winding and sending it to the distributor. From there, it gets sent to one of six spark plugs, depending on where you are in the combustion cycle.

Causes of Ignition Coil Failure In Jaguar

Here are some common causes of an ignition coil failure in Jaguar vehicles:

  • Dirty or Contaminated Fuel: Contaminated fuel is a common cause of ignition coil failure in many vehicles, including Jaguar models. Debris in the gas tank, rust, and water in the tank, or having too much alcohol content in your fuel can all lead to problems with your ignition coil.
  • A bad connection between two or more wires: If two or more wires touch each other where they shouldn’t, they can cause a short circuit which will blow fuses or damage parts like your car’s computer or even worse, cause a fire! The best way to fix this problem is by replacing all wires with new ones.
  • Check Engine Light: The easiest way to tell if your ignition coil has failed is to check your dashboard for an engine warning light. When this light comes on, it could mean there is an electrical problem in your vehicle. Bring your car to our auto center for a proper diagnosis for error codes, which will pinpoint the problem and allow for only the necessary repairs.
  • Decreased Fuel Efficiency: If you notice that your gas mileage has decreased, it could be because of a failing ignition coil. A failing ignition coil will not send enough electricity to the spark plugs, so they cannot ignite the fuel properly and cause the engine to run inefficiently.
  • Oil leaking on top of the coils: When oil leaks onto the coils, it can seep into them and short out electrical connections. This causes them to overheat and short out.
  • Excessive vibration: This will cause mechanical damage to the internal components of the coil.
  • Overheating: Overheating damages the internal windings of your ignition coil and reduces its lifespan. The most common cause of this problem is a faulty spark plug. The spark plugs are designed to ignite the fuel mixture for combustion in your engine. If you notice that your car has low power during acceleration, then your spark plugs are not working properly. They may need to be replaced or rebuilt.

What to Do When Your Ignition Coil Fails

The ignition coil is a very important component of the ignition system, and when it fails, it can cause serious problems with starting or running your vehicle. A malfunctioning coil can even lead to a non-starting condition. If you suspect that your ignition coil is faulty, you should have it checked immediately.
