In 1996, an orange light on your car's dashboard labeled "Check Engine" or "Service Engine" became standard on all car makes and models. The check engine light tells you there's a problem with your car's engine and powertrain control system. Diagnostics must be run by trained professionals using proper equipment to clear check engine light.

Do I Need Check Engine Light Service?

An illuminated "Check Engine" or "Service Engine" light indicates a problem detected by your car's on-board diagnostic system. The check engine light cannot indicate the exact nature of the problem -- only the right training and diagnostic equipment can do that.

Typical Service When Check Engine Light Comes On

• A flashing light indicates a problem that is currently happening and may require immediate attention, whereas a steady light can be diagnosed at the first convenient opportunity. 
   
• A technician connects a "scan tool" to your car's onboard diagnostic system to determine the problem. 
   
• Further testing and diagnostics may be required to pinpoint the exact cause of the problem. 
   
• Once the problem is identified, repairs are made and we reset the check engine light.
