A check engine light on your car’s dashboard can be particularly concerning if you’re not sure what it indicates. While an auto repair shop can give you a definitive answer upon inspecting your car, it helps to know what causes the indicator to light up. Here are a few reasons why your car might be flashing the dreaded sign.

4 Reasons the Check Engine Light Is On

1. Faulty Spark Plug

In some cases, the light might turn on if there’s a problem with the spark plug or the wiring that connects it to the ignition coil. Spark plugs help ignite fuel and power up the engine, so a problem with them will reduce the car’s efficiency. Additionally, faulty plugs might also cause damage other engine components, like the oxygen sensors and catalytic converters.

2. Damaged Catalytic Converter

This important component makes your car more environmentally friendly by turning toxic carbon monoxide into carbon dioxide. A lit-up check engine sign could be indicative of a problem with the catalytic converter and warrants urgent auto repair solutions. If not replaced in time, this can affect a car’s fuel economy and cause it to fail an emissions test.

3. Loose Gas Cap

A loose and improperly fitted gas cap might also prompt your check engine light to flash on the dashboard. This is the first place to inspect whenever the light pops on and could lower the car’s fuel efficiency. If the cap is tightly secured and the light is still on, contact an auto mechanic to inspect your vehicle as soon as possible.

4. Inefficient Oxygen Sensors

Inefficient oxygen sensors are less serious than other auto repair problems that cause the engine sign to start flashing. These components keep a tab on the amount of unused oxygen in the exhaust unit. An issue with them can lead to higher fuel consumption, in addition to taking a toll on the spark plug and catalytic converter.
