Why Is Your Check Engine Light Flashing? This Common Fix Could Save Your Wallet—and Your Car! Have you ever stared at your dashboard and seen the check engine light illuminate—especially when it starts flashing instead of just glowing steadily? That red light isn’t just a warning; oftentimes, it signals a serious issue that demands immediate attention. While a steady check engine light might indicate a minor problem, a flashing engine light means your vehicle is under stress, potentially leading to costly damage if ignored. Why a Flashing Check Engine Light Is Serious Unlike a steady check engine light, which can point to less urgent issues like a loose gas cap or a slightly faulty sensor, a flashing check engine light signifies a severe mechanical or emissions problem. In most cases, when this light flashes, your car’s engine control unit (ECU) cuts fuel delivery to protect the emissions system—effectively turning your vehicle into a driving hazard.
