Check Engine Light Diagnosis
The check engine light will turn on when a sensor within the vehicle detects a problem. Sensors in your car monitor everything from spark creation, gasses, intake measurements, idle speed and so many other things. Even a slight miscalculation or malfunction from one system within your car could trigger the light to come on. It is important to note that many issues are quite small and can be repaired rather inexpensively when addressed as soon as the light illuminates. Waiting to have diagnostics ran could allow time for the issue to grow much worse and the repairs more expensive.
What causes the check engine light to come on
Some of the most common issues that will trigger the check engine light are rather simple, such as misfiring spark plugs or even a loose gas cap. Other issues include a malfunctioning oxygen sensor or mass airflow sensor. One of the biggest problems that could trigger this light is a faulty catalytic converter. This is a part of the exhaust system that converts hazardous exhaust fumes into less harmful emissions. It is expensive to replace but generally won't malfunction unless another part fails first, which would likely have made the check engine light turn on beforehand.
