Why is my Nissan Check Engine Light On?

We have found at United Nissan of Las Vegas that there are five main causes of your check engine light being on.

• Oxygen Sensor – your oxygen sensor monitors the unburned oxygen in your exhaust system. When the oxygen sensor is faulty, it will cause your engine to burn more fuel than needed.
• Gas Cap– Loose, missing, or damaged gas caps will not seal the fuel system and pressure will be lost.
• Catalytic Converter– your catalytic converter converts harmful carbon monoxide into carbon dioxide. Poor maintenance or other damages can cause your engine to run hot and will cause the check engine light to come on
• Mass Airflow Sensor – faulty sensors often cause the check engine light to come on because the air/fuel blend is inefficient
• Spark Plug Parts – Spark Plug Parts ignite the air/fuel blend. If your spark plug parts go bad, a misfire condition will cause the check engine light to come on
