A List of Potential CEL Problems

The check engine light (CEL) is part of your vehicle’s onboard diagnostic system (OBD). When this light comes on, the OBD system detects a problem with the components of your vehicle’s engine or emissions system. One common problem that can trigger the CEL is a faulty oxygen sensor. This sensor monitors the amount of oxygen in your vehicle’s exhaust system. If it fails, it can cause your engine to run poorly or even damage your catalytic converter. The repair for a faulty oxygen sensor is relatively simple, involving the replacement of the sensor itself. A malfunctioning mass airflow sensor is another common problem that can trigger the CEL. This component calculates the amount of air entering your engine and adjusts the fuel-to-air ratio accordingly. A failing mass airflow sensor can cause your engine to run rough, stall, or even fail to start altogether. Repairing a mass airflow sensor can involve cleaning or replacing it entirely. Your catalytic converter can also trigger the CEL. This component is responsible for reducing harmful emissions. It can fail due to wear and tear or damage caused by road debris. When a catalytic converter fails, it can decrease engine performance and increase emissions. The repair of a failing catalytic converter can be expensive, involving the replacement of the entire unit.

Although your CEL can be prompted by something complex, it can be as simple as a loose or damaged gas cap. This may seem like a minor issue, but an improperly sealed gas cap can cause your vehicle’s emissions system to malfunction, leading to decreased engine performance and increased emissions. No matter what kind of problems result from your CEL, you can rest easy knowing that Provision Automotive can help fix the issue.
