Expert CEL Diagnostics and Repair
Overview of the Check Engine Light
The check engine light (CEL) is an ambiguous warning light, as it can signal a variety of issues. Essentially, it is the messenger of your onboard diagnostics system (OBD-II). The OBD-II system constantly monitors all major functions of your vehicle, including the engine and transmission, through various sensors. If it detects an issue with a system or function, it catalogs it in your vehicle’s internal computer and prompts the CEL to illuminate. The part that gets cataloged is known as the diagnostic trouble code (DTC), also known as an error code. This code provides information on what and where the problem is and is retrieved through a diagnostics service. At ONB Automotive Repair in Everett, Washington, we possess the know-how and tools to properly run diagnostics, inspect the vehicle, and fix the problem. We have decades of collective experience performing check engine light diagnostics and repair for all makes and models. If your check engine light has come on, get in touch with us today!
What Does the Check Engine Light Mean?
While it is called the check engine light, problems with the transmission, exhaust, electrical, and others can trigger it to come on. Some of the most common reasons for the CEL are a faulty oxygen sensor, loose or damaged gas cap, failed catalytic converter, malfunctioning mass air flow sensor, bad ignition coils, and faulty EGR valve. Along with the illumination of the CEL, you may experience symptoms of a problem such as reduced power, rough idling, increased fuel consumption, strange noises, colored exhaust smoke, or overheating. It’s important to have a professional address the underlying issue causing the check engine light to prevent potential damage to your vehicle and restore optimal, safe performance. When the check engine light illuminates, we recommend scheduling an appointment at your earliest convenience. The only way to know for certain why your CEL is on is to bring your vehicle in for diagnostics. Our auto repair shop is open Monday through Friday.
