Understanding Underlying Causes

The CEL can feel overwhelming when you don’t know the problem, but we don’t want the experience to feel that way for you. With a lamp that appears solid after the initial vehicle start-up phase, which is what you’ll see in nearly every situation, you can drive to reach our shop for assistance. First, let’s discuss why it’s there. The light is part of a federally mandated system to limit harmful vehicle emissions in the United States. Second, when you bring your car to us, we’ll diagnose it accurately. We connect your vehicle’s OBD-II port to our computerized equipment to obtain a trouble code. Using that, along with our expertise, we pinpoint the specific problem that needs attention. Finally, we let you know what’s wrong and take care of the issue for you. Sometimes, the problem is as simple as a poorly fitting or loose gas cap. This breaks the fuel system’s seal, allowing fumes to escape. More often, however, the underlying cause can be found with the mass airflow sensor or oxygen sensor. Respectively, these measure the amount of air entering the engine that can be used in combustion and the amount of unburned oxygen in the exhaust. Other causes include aging spark plugs, frayed spark plug wires, or a failing catalytic converter.
