Check Engine Light Diagnosis

What is Check Engine Light Diagnosis??

Your car's computer constantly monitors input from various sensors in critical locations on the vehicle. When the data from one of these locations indicates a potential problem, your Check Engine light fires up in the dash panel. Because of the variety of reasons the light can appear, it is necessary for a second computer or diagnostic system to "speak" with your car's computer to determine the error code generating the light. Some codes may even point to specific parts, such as temperature sensors that need to be assessed and potentially replaced.

What You Should Do If Your Check Engine Light Comes On

A steady-state Check Engine light is generally not a sign of an emergency. When your light comes on while driving, start to review other potential indicators on your dashboard: Is your menu presenting any additional information about a problem? Are any other warning lights or notifications activated? If you see a flashing Check Engine light, you are experiencing a more urgent problem. You should contact our service center immediately as the continued operation may negatively impact your vehicle.

Making Sure Your Check Engine Light is Working Properly

Reasons for a Check Engine light to activate are varied, but all indicate a change in your system is impacting sensor readings. The light can refer to a more significant fuel system problem, temperature issues, engine pressure problems, or a failure with the sensors providing the data.
