Do you know what the check engine light (CEL) means? The check engine light serves as an indicator of a potential issue detected by the onboard diagnostics system (OBD-II) in modern vehicles. Connected to various sensors throughout the vehicle, the OBD-II continuously monitors key components, such as the engine and emissions system. When abnormalities are detected, such as irregular sensor readings or system malfunctions, the OBD-II triggers the check engine light to alert the driver. It also creates a diagnostic trouble code (DTC) that details the problem. This system enables quick identification of potential problems, allowing for timely diagnostics and repairs. At All Wheel Drive Auto in Kirkland, Washington, we offer expert Subaru check engine light diagnostics for our Subaru customers. By interfacing with the OBD-II system, our Subaru technicians use advanced equipment to extract the DTC to pinpoint the specific issue and provide the right solution. If your CEL is on, come by today.

The check engine light can illuminate for numerous reasons. Some of the more common problems include a faulty oxygen sensor, which measures the oxygen levels in the exhaust gasses and helps regulate the fuel mixture for optimal performance. Malfunctioning oxygen sensors can lead to decreased fuel efficiency and increased emissions. Another common culprit is the catalytic converter, which helps convert harmful pollutants in the exhaust into less harmful emissions. A failing catalytic converter can result in increased emissions and decreased engine performance. Problems with the mass airflow sensor, evaporative emissions system, or ignition system can also trigger the check engine light. It’s essential to address the underlying cause promptly to prevent further damage and ensure optimal vehicle performance and emissions compliance. In some cases, you may experience a flashing check engine light. This indicates a serious engine malfunction that requires immediate attention, as it signifies a potentially severe problem, such as a misfire that could cause extreme damage.
