Marion Check Engine Light
You’re driving your Chevy in Marion, and the check engine light (CEL) comes on. If you’re wondering what to do, you’re not alone. We’ll explain why it may have turned on and outline the best steps to take.
The check engine light usually doesn’t indicate an emergency, so there’s no need to panic. It could be something as minor as a loose gas cap. However, there are instances when it signals a more serious issue. Whatever the reason, when the check engine light comes on, bring your vehicle to the Jim Cook Chevrolet Service Center for CEL testing and diagnosis in Marion.
Understanding the Check Engine Light
When the check engine light appears, it will either be steady or flashing. A steady light indicates a situation that needs to be checked and remedied, while a flashing light is a signal of something serious that must be addressed quickly.
A flashing check engine light often means the ignition system is misfiring, allowing unburned fuel to enter the exhaust system. This can damage the catalytic converter, leading to costly repairs. If your check engine light is flashing, pull over immediately, turn off the engine, and call for roadside assistance.
If the light is steady, the issue still needs attention but isn’t an emergency. In this case, schedule a service appointment at the Jim Cook Chevrolet Service Center. A steady check engine light can indicate a range of issues, including a faulty oxygen sensor, a failing catalytic converter, a damaged gas cap, a malfunctioning mass airflow sensor, or worn spark plugs.
These are some common causes of a check engine light:
Faulty Oxygen Sensor
Your Chevrolet’s oxygen (O2) sensor monitors the amount of unburned oxygen in the exhaust system. If the sensor fails, the engine will burn more fuel, reducing fuel efficiency. If left unchecked, a faulty O2 sensor can also damage the catalytic converter or spark plugs.
Failing Catalytic Converter
The catalytic converter reduces harmful emissions by converting carbon monoxide into carbon dioxide. If it stops working properly, fuel efficiency will decline, engine performance may suffer, and the vehicle may fail an emissions test.
Loose, Damaged, or Missing Gas Cap
Though small, the gas cap is essential for preventing fuel vapors from escaping. If it’s loose, tightening it may resolve the issue. However, a damaged or missing gas cap should be replaced to prevent fuel evaporation and reduced gas mileage.
Malfunctioning Mass Airflow Sensor
The mass airflow sensor measures the air entering the engine and determines how much fuel is needed for optimal performance. A failing sensor can lead to reduced fuel efficiency and potential damage to the catalytic converter, spark plugs, or O2 sensor.
Worn Spark Plugs
Faulty spark plugs or wires can damage the ignition system, catalytic converter, and oxygen sensors. You may experience reduced performance and lower fuel economy.
Schedule a Diagnosis
If your Chevrolet’s check engine light is on, don’t ignore it. Whether the issue is minor or severe, prompt diagnosis can prevent more expensive repairs down the road. Contact the Jim Cook Chevrolet Service Center in Marion to schedule your appointment or book your visit online.
