What Does It Mean When The Nissan Check Engine Light Flashing? (2023)

When the Nissan check engine light flashing, it indicates a severe problem with the vehicle’s emissions control system. This means that the engine’s performance and emissions are being impacted by the issue in real-time. The flashing light is a warning sign that should not be ignored, as it can lead to further damage and potentially more expensive repairs if left unaddressed.

Some common causes of the Nissan check engine light flashing include:

• Malfunctioning oxygen sensor: The oxygen sensor is responsible for monitoring the air/fuel mixture in the engine, and if it is not functioning properly, it can cause the check engine light to flash.
• Catalytic converter failure: The catalytic converter is responsible for reducing emissions from the engine, and if it fails, it can cause the check engine light to flash.
• Misfiring engine: If the engine is misfiring, it can cause the check engine light to flash. Misfiring can be caused by a range of issues, including a faulty spark plug, ignition coil, or fuel injector.
• Evaporative emissions (EVAP) system leak: The EVAP system is responsible for preventing fuel vapors from escaping into the atmosphere, and if there is a leak, it can cause the check engine light to flash.
