You just filled up your tank and now that dreaded check engine light is glowing on your dashboard. What gives? This happens more often than you'd think, and it's usually not as scary as it seems. A loose gas cap is the most common culprit because modern cars monitor fuel system pressure constantly. If the cap isn't sealed tight after refueling, sensors detect a leak and trigger the warning light. Sometimes you'll need an Auto Repair Shop Federal Way to reset the code even after tightening the cap. Other times, it could be a faulty purge valve or even contaminated fuel from the pump. Don't panic yet, but don't ignore it either. A Local Mechanic Shop near me can plug in a scanner and tell you exactly what's going on before a small issue becomes expensive.
