3 Common Reasons Your Check Engine Light Could Turn On, Russellville, Arkansas

Of all the dashboard lights you might see in your vehicle, few can be more alarming than the check engine light. Is your car in serious damage? Do you need to visit a mechanic immediately? Unfortunately, figuring out why it has turned on isn’t always easy. The auto maintenance team at A-1 Tire Distributors in Russellville, AR, shares a few of the most common reasons for the check engine light to turn on.

Why the Check Engine Light Has Turned On

1. Loose Gas Cap

If your cap is loose or missing, the check engine light will generally turn on. It never hurts to check if this is the problem before visiting a mechanic.

2. Mass Airflow Sensor Problems

The mass airflow sensor measures the air intake and directs the fuel injectors to add more or less gas, which helps the engine run more efficiently. When this component is experiencing problems, you won’t just notice yourself filling up your tank more often, but it could also lead to severe damage to the spark plug and catalytic converter. If your engine frequently idles or stalls, visit a professional as soon as possible to check the mass airflow sensor.

3. Damaged Oxygen Sensor

There’s an oxygen sensor in your car’s exhaust system, but it also plays a crucial role in engine performance. By measuring unburned oxygen levels, it helps your car achieve better gas mileage. A faulty sensor can result in a sharp decline in fuel efficiency and potential damage to your vehicle’s spark plug, causing the engine to idle or stall. Ideally, the oxygen sensor should be replaced every 60,000 to 90,000 miles, as it tends to wear down over time.
