Simply put, when the check engine light illuminates in a 2015 Nissan Sentra SV, it signifies an issue detected by the car's engine computer. A flashing light indicates a more severe problem, such as a potential misfire that can result in catalytic converter overheating. It's crucial not to drive if the light is flashing, as the problem could range from a minor hiccup like a loose gas cap or changes in humidity to a major component failure like a faulty catalytic converter. The potential causes triggering the check engine light are numerous. Initially, if the light turns on, check if the gas cap is securely fastened. If loose, tighten it and continue driving, understanding that it may take some time for the light to turn off even after tightening it.
