Prescott Valley Check Engine Light

Your vehicle’s check engine light (CEL) is a warning that the onboard diagnostics system has detected an issue with one of the car’s systems. While it may seem scary, there’s no reason to panic. The check engine light is usually a sign of a minor problem like a faulty sensor, a bad spark plug, or even a gas cap that’s come loose. But it can also alert you to a serious problem, including a broken catalytic converter. While there’s no reason to panic, when the light illuminates, you should take care of it as soon as you can. If you live in Prescott Valley, check engine light service fast and easy when you bring your car to Flagstaff Chevrolet.

When the car’s built-in diagnostics system identifies an engine problem, you’ll notice the check engine light come on. It will either be a yellow or orange outline of an engine. You’ll also see the words “check” or “service engine.” If the light comes on and it’s steady, it indicates a problem that’s not serious but needs to be taken care of. If the light is flashing, it’s a serious issue that needs immediate attention. In both cases, you should bring your car to the Flagstaff Chevrolet Service Center for CEL testing & diagnosis near Prescott Valley.

CEL Testing & Diagnosis in Prescott Valley

A flashing check engine light is usually due to a misfiring engine or another serious issue you should attend to right away. Don’t ignore a flashing check engine light. If you don’t fix the issue, it can lead to more problems, including a damaged catalytic converter, an expensive part to replace. So, if you see a blinking check engine light, take your car for service immediately.

A steady check engine light can mean your vehicle’s gas cap is loose or damaged. Check the cap and tighten it if it’s loose. If the gas cap is damaged, replace it. If the light goes off after taking care of the gas cap, you’ll know that was the issue.

If the gas cap wasn’t the cause of the problem, you’ll need to bring your car to the Flagstaff Chevrolet Service Center. We have the specialized equipment necessary to evaluate the reason the check engine light has come on as well as the experience to fix your vehicle correctly. Your car may have a faulty oxygen sensor, a damaged spark plug, or another broken part.

Your vehicle may seem to be operating properly when the check engine light comes on. But it’s a warning that there’s a problem. Ignoring it will make the situation worse. If your car’s check engine light is on, your vehicle will fail an emissions test. You may notice reduced performance and lower fuel economy.

If your car’s check engine light has come on and it’s flashing, head up to the Flagstaff Chevrolet Service Center right away for check engine light service. We’ll help you quickly. If the light is solid, call us at 888-495-0038 to make an appointment for service or use our website’s Service Appointment page.
