Understanding Ignition Coils: What Every Changan Driver Should Know

Your car’s engine relies on a crucial component to start and run smoothly — the ignition coil. Though it’s a small device, its role in your vehicle’s ignition system is critical. If you’re experiencing engine misfires, rough idling, or trouble starting your car, a faulty ignition coil could be the issue.

In this guide from Changan South Motors, we’ll break down what an ignition coil does, how to recognize the signs of failure, when it needs replacing, and why it matters for your vehicle’s performance and safety.

What Is an Ignition Coil?

An ignition coil is an electrical transformer that boosts the 12 volts from your car’s battery into the high voltage needed to ignite the air-fuel mixture inside your engine’s combustion chamber. This spark is what powers your vehicle.

In modern vehicles — including advanced models like the Changan Deepal S07 and Changan Oshan X7 Comfort — ignition coils are designed for maximum efficiency, often with individual coils for each cylinder to enhance both fuel economy and performance.

Symptoms of a Failing Ignition Coil

A failing ignition coil can cause several noticeable issues:

  • Engine misfires

  • Illuminated check engine light

  • Decreased fuel economy

  • Rough idling

  • Trouble starting the engine

  • Power loss during acceleration

If you drive models like the Karvaan MPV Plus 1.2 MPFi, these symptoms can affect overall driving comfort and reliability — don’t ignore them!

When to Replace an Ignition Coil

On average, ignition coils can last around 100,000 kilometers, but they can wear out sooner depending on driving conditions and usage. Here are some signs it’s time for a replacement:

  • Frequent stalling or misfiring

  • Persistent check engine light

  • Trouble codes related to ignition during diagnostics

It’s also a good practice to check and possibly replace spark plugs at the same time, since they work closely with ignition coils for proper engine combustion.

And if your battery is weak or outdated — which can strain the ignition coil system — consider a replacement through our battery services.

Is It Safe to Drive with a Bad Ignition Coil?

Driving with a bad ignition coil is not advisable. It can lead to:

  • Engine damage

  • Increased emissions

  • Lower fuel efficiency

  • Complete engine breakdown

If you’re on the road or planning a long trip, it’s best to address ignition issues before they escalate. For peace of mind, book a check-up at Changan South Motors.

Ignition Coil vs. Spark Plug: What’s the Difference?

Although often confused, ignition coils and spark plugs serve different roles:

  • Ignition Coil: Generates the high voltage.

  • Spark Plug: Uses that voltage to ignite the air-fuel mixture.

A failure in one can affect the other, so it’s important to inspect both when performance issues arise.
