The check engine light is an alert that lets you know that your car’s onboard diagnostics system has detected a problem with the fuel, emissions, ignition or exhaust system. In most cases, the check engine light isn’t serious. You’ll see a steady light come on when you start the car that stays on. It can be caused by something as minor as a loose gas cap.

If the light is flashing, it means there’s a serious problem that needs CEL diagnosis & testing near Glenwood. A flashing check engine light is a warning of a serious issue like a damaged catalytic converter or an engine problem. You must bring the vehicle to a service technician immediately. Don’t put this off, because disregarding a blinking check engine light can turn into a big problem that can result in damage to your vehicle’s catalytic converter, which is a costly part to replace.

When the check engine light is lit but isn’t flashing, there are a few things you try before bringing it in for service. Check the gas cap. If it’s loose, tighten it. If it’s broken or missing, replace it with a new one. If the gas cap was the culprit, the light will turn off during the next couple of days.

If you’ve ruled out the gas cap as the cause of the problem, you’ll need to bring your car to our service center. Our expert service technicians will use special electronic equipment to read the diagnostic codes and ascertain the cause of the check engine light. Several components can trigger the light, including a bad spark plug or a faulty sensor.
