Simply put, the check engine light is a warning. It informs drivers that something is beginning to malfunction within their vehicle and if not promptly taken care of, can cause serious damage. Although many people see the light and think that their vehicle is in imminent danger, the reality is that your vehicle is ok, for the time being. The light allows you to be proactive and get ahead of the problem and, if anything, should be looked at with more praise. The only thing that’s frustrating about the light is the lack of context it provides. It will let you know something’s wrong, but it won’t let you know what the problem is.
The check engine light is triggered by sensors found in your vehicle. These sensors pick up abnormal movement from your vehicle and register that movement into your vehicle’s computer system. If it’s concerning enough, that’s when your vehicle triggers the light. The only problem with the light is the failure of clearly defining the problem, but many drivers are able to remedy that by utilizing an engine light diagnostic tool. Others keep their eyes and ears open for common signs. Here are a few you can look out for:
Loose Gas Cap
Bad Spark Plugs/Wires
Malfunctioning Cataliytic Converter
As mentioned before, the check engine light is a warning. It informs drivers when something is beginning to malfunction in their vehicle. If a driver decides to ignore the light, not only will they cause more damage to their vehicle but they may also face a more expensive repair bill. The light gives you a chance to prevent that situation from happening and should be acted upon at the driver’s earliest convenience!
