Hello, there are quite a few reasons your check engine light can illuminate. First - if you go to the "common problems" section of RepairPal and enter your vehicle information, you can type in "Check Engine Light" and get some more frequent causes. Go here: https://repairpal.com/problems As a general note, the check engine light will come on when the vehicle's engine processor detects a fault within one of many operating systems that influence engine performance. When a fault is detected, it sets the light to come on and get your attention. Some concerns are more detrimental than others. Most times the fault affects proper emissions controls which can be damaging to the environment. But - they also illustrate performance issues that can cause bigger problems if not resolved. Seek guidance at a local shop near you who can help diagnose your concern. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
