Ignition Coils on the 2015 Mitsubishi Lancer: What They Do and When to Replace

The 2015 Mitsubishi Lancer is a popular choice among Aussie drivers, known for its reliability and straightforward engineering. One component that plays a crucial role in this vehicle's engine performance is the ignition coil. Many people might not give ignition coils much thought until an issue pops up, but these little parts are vital to how the Lancer runs smoothly and efficiently.

Ignition coils are integral to the 2015 Mitsubishi Lancer's ignition system. This model utilises a typical coil-on-plug setup, where each ignition coil is mounted directly on top of the spark plug. This design improves ignition precision and reduces energy loss compared to older systems that used a single coil and distributor. So yes, the 2015 Mitsubishi Lancer definitely uses ignition coils, and without them, the engine wouldn't start or run properly.

Simply put, the ignition coil transforms the 12-volt power from your car's battery into the thousands of volts needed to create a spark at the spark plugs. That spark ignites the air-fuel mixture inside each cylinder, which is necessary for the engine to generate power. Without ignition coils functioning correctly, the combustion process can misfire or stop altogether, leading to rough idling, poor fuel economy, and even engine stalling.

Given their importance, keeping the ignition coils in good shape is essential as part of regular maintenance on your 2015 Mitsubishi Lancer. While these coils tend to last a good while - often more than 100,000 kilometres - they are not immune to wear and tear. Over time, heat, vibration, and electrical stress can cause internal coil windings to break down or the insulation to deteriorate. This can result in weak or inconsistent sparks, causing symptoms that are quite familiar to Lancer owners.

Some common signs that an ignition coil might be failing include:

• Engine misfires or hesitation during acceleration
• Check engine light turning on, sometimes with a code related to ignition issues
• Rough idling or difficulty starting the engine
• Poor fuel economy and increased emissions
• Noticeable drop in power and performance

When your Lancer shows these symptoms, it's a good idea to have the ignition coils tested. Most workshops can quickly check coil function using diagnostic equipment or even simple resistance tests. If an ignition coil is found to be faulty, replacing it is generally straightforward and affordable compared to other engine repairs.

Replacing ignition coils on a 2015 Mitsubishi Lancer typically involves removing the engine cover (if fitted), unplugging the electrical connector from the faulty coil, and then unbolting the coil from the spark plug well. After fitting the new coil, it's best to clear any error codes using a diagnostic tool. This ensures the vehicle's computer reset takes place, preventing any lingering misfire alerts.

One useful tip when changing ignition coils is to replace them in pairs or all at once if your car has high mileage. This can help maintain consistent spark performance across all cylinders and reduce the chance of more misfires soon after a single coil replacement. It's also a good idea to inspect the spark plugs during coil replacement since worn plugs can place extra strain on the coils.

If you're servicing your own 2015 Mitsubishi Lancer, be mindful of using high-quality replacement coils that meet or exceed Mitsubishi's standards. Cheaper aftermarket options might tempt you with a lower price tag, but they can cause issues down the line, including premature failure or erratic engine performance.

Maintenance-wise, ignition coils themselves don't require regular servicing beyond visual inspections and diagnostics if symptoms arise. However, keeping your engine bay clean, avoiding water intrusion near the coils, and addressing misfires promptly can prolong coil life.

In short, the ignition coil is a must-have component on the 2015 Mitsubishi Lancer that ensures your engine sparks to life every time you turn the key. Proper care and timely replacement of ignition coils will help keep this reliable vehicle running smoothly, maintaining that familiar spirited drive and fuel efficiency Mitsubishi owners appreciate.
