Strange that such a small light can ignite such fear! Perhaps it’s the utter lack of follow-up information it provides, or the sense of foreshadowing it seems to impart, but one thing remains certain – nobody likes the “Check Engine” light.
It has happened to most of us at one point or another. And what makes it so scary is that the problem it is signaling can range from a very simple fix to a very serious problem. We find ourselves wondering how long we can ride it out before getting it looked at… but no matter how well your vehicle seems to be running, this little light should never be ignored. It is part of your vehicle’s computerized diagnostic system and could be warning of you of an important issue that needs to be addressed. As it’s important that a car is completely safe to drive, it’s often better to get a professional mechanic to look at the car and fix it. They will have expert knowledge and should be experienced with fixing these problems. A check engine light can actually cause a car to fail on an emissions test, so be sure to get it fixed straight away.
Interesting facts: for any vehicle, the check engine light could mean that there is a failure somewhere in your vehicle’s electronic engine control system. If the solenoids, actuators, or electronic sensors are not working properly, the light may come on as a signal of these issues and may require you to research into motor parts similar to these part options so you’re able to find the suitable part and replace it. After 1996, however, all cars and trucks required more strict exhaust emissions guidelines, so your check engine light on those vehicles will not only monitor the electronic sensors, actuators, and solenoids; but also the vehicle’s emissions.
These new systems are so sensitive that the check engine light may come on even if you don’t fasten the gas cap properly. Also, be sure not to mistake the check engine light for the service or maintenance lights, as these lights have a different meaning then the check engine light, and often refer to a regular requirement like a tune up. They will light up at a specified mileage milestone to let you know that service is required.
So (after checking your gas cap of course…) when you see that check engine light come on, the only way to diagnose the problem for sure is to get it checked out by a licensed mechanic. Learn more about our electrical system service.
