Check Engine Light On? Don’t Ignore It This Fall

Your check engine light (also called the service engine or malfunction indicator lamp) is your vehicle’s way of telling you that something isn’t right.

When your car’s computer detects an issue, it stores trouble codes that correspond to specific problems, anything from a small emissions issue to major mechanical failure.

Some of the most common causes we see at Don Hattan Derby include:

• Loose or faulty gas cap – often triggers the light after refueling
• Oxygen sensor failure – affects fuel economy and emissions
• Bad ignition coil or spark plugs – causes misfires or rough idling
• Catalytic converter issues – impacts emissions and performance
• Mass airflow sensor failure – reduces fuel efficiency
• Wiring or sensor faults – disrupt communication with your car’s computer

Even if your car seems to run fine, ignoring that light can lead to costly engine repairs down the line. That’s why it’s best to have your vehicle checked as soon as possible.

As fall turns to winter in Kansas, your vehicle’s engine works harder to perform in cold conditions. Fluids thicken, batteries weaken, and sensors become more sensitive to temperature changes.

A minor engine performance issue that might seem harmless in warm weather can quickly escalate when it’s below freezing. For instance:

• A weak ignition coil can make cold starts harder.
• A dirty fuel system can cause misfires.
• A loose gas cap might trigger the check engine light repeatedly due to fluctuating pressure.

If your check engine or service engine soon light is glowing, it’s especially important to schedule diagnostics before winter sets in. A small fix now could prevent a big engine repair later.
