Why Is My Check Engine Light On?

What Happened to My Car?

Haver’s Auto Repair on West Center Road in Omaha, Nebraska frequently helps drivers with check engine light service. We hear their questions all the time. “Why is my check engine light on?” “What happened to my car since I last drove it?” We understand their confusion. One moment, they are driving their vehicle and everything is perfectly normal, then the next time they get in the car a warning light is illuminated. It’s a cause for concern, but before you start to panic, let our team help you explore the possibilities.

Common Check Engine Light Causes

Loose Gas Cap

If you just pumped gas before you notice your check engine light come on, take a moment to check your gas cap. Sometimes the warning indicator warns drivers if the cap was not properly tightened after refueling. The light may not go off immediately after you put the cap back in place, so give your car a few miles to adjust to the change. If the light stays on, schedule an appointment with us to look into the issue further.

Worn Out Spark Plugs

When was your vehicle’s last tune-up service? If your first thought after reading that was “oh no, it’s been a while,” your check engine light could be illuminated because of a worn-out spark plug. It’s a simple fix. While you take care of that, ask your technician to check and clean the oxygen sensors, air filter, and fuel filter as well. These are items normally handled during routine tune-ups.

Understanding the Warning

These are only a couple of common causes, but there may be various other reasons why your vehicle’s check engine light is on. A technician at Haver’s Auto Repair on West Center Road can tell you for sure. Just know that the light is your signal to seek professional help. From the last time you drove your vehicle, its computer monitoring system found a malfunction that needs repair. It triggered the light to alert you so you can find an expert to perform diagnostics and repair. It’s unlikely that anything very serious happened to your car overnight and as long as you’ve kept up with your vehicle’s maintenance needs, you may need something as simple as new spark plugs or oxygen sensors to disarm the alert.
