Before coming in for maintenance, it is possible to learn a little bit more about why the light came on. Some newer model vehicles display a diagnostic code on the dashboard, which can help give you some insight into the problem. You can do so by looking up the code in the driver's manual, or online. Keep in mind that the code will only point to the general source or location of the issue. Most likely, a licensed mechanic will need to fully identify and repair the problem. Here are a few of the most common causes:
•The gas cap is loose. Try tightening it and see if the light turns off.
•The mass airflow sensor or oxygen sensor needs replacement. If these parts are malfunctioning, the vehicle may have reduced fuel economy and suffer possible damage to other engine parts.
•The catalytic converter is damaged. This part is critical to the emissions system and damage will hinder performance and fuel economy.
It’s okay to err on the side of caution when the check engine light comes on. However, never ignore this alert. A timely checkup could easily prevent much more costly repairs down the road. To get your vehicle checked or for routine maintenance, reach out to the Experts at Melloy Dodge!
