On the dashboard of every automobile is a “check engine” light, yet nobody likes to see that light turn on. There are many reasons why your check engine light can be on. This indicator tells you whether your vehicle needs one or more engine or exhaust system replacements. Catalytic converters, oxygen sensors, mass airflow sensors, spark plugs, wires, broken gas caps, vacuum leaks, failed exhaust gas recirculation valves, dead batteries, and issues with car alarms are just a few examples of the parts that you might need.
While a flashing “check engine” light may suggest an urgent diagnosis, a solid “check engine” light should be repaired as soon as possible.
