Why Is My Check Engine Light On?

It’s a common thing to do. That pesky orange light on your dashboard comes on, and you choose to ignore it. It’s just a light. It can’t be that big of a deal. Right?

Your car has an onboard diagnostics system that constantly monitors multiple aspects of your car’s operation. When any part of that system detects a problem, it will cause the check engine light to come on. Here are a few typical issues that can trigger the warning.

Loose Gas Cap

While it might seem like it couldn’t cause a problem, the fuel cap is an essential piece of your vehicle. It protects your fuel supply from contamination while also keeping dangerous fumes from leaking out of your tank. If a loose gas cap is the cause of your check engine warning, the light will go off again once you tighten the cap and drive a little more.

Faulty Spark Plugs

Spark plugs create power in your engine by igniting a spark. As spark plugs wear out, they often begin to misfire, causing slower acceleration and a decrease in fuel efficiency.

Transmission Trouble

It may seem like transmission issues should not trigger a check engine light, but your car’s transmission and engine work closely together. Anything from solenoid malfunction to low transmission fluid levels can cause the light to come on.

Urgent Repair Needed

If your check engine light is red or flashing, immediately pull over and shut off your engine. Have your car towed to a trusted repair shop to diagnose the issue. If you continue driving with that flashing light, you risk causing thousands of dollars in damage to your car.

Since such a wide range of issues can trigger this one light, the only way to be sure of the cause is to have a trusted mechanic run a diagnostic test. We can easily track down your car’s problems and make any necessary repairs to get you back on the road safely. Don’t run the risk of making any car problems worse. Make an appointment today!
