Check-Engine Light Diagnosis

Flashing vs Lit Check Engine Light

A lit check engine light means the computer of your vehicle (ECU) has received a signal from a sensor in the vehicle informing the ECU that something is out of the ordinary. It could be something as simple as a loose gas cap or as major as a mechanical failure that requires diagnosis and repair as soon as possible. 


A flashing check engine light means the engine is not running as it should and the vehicle needs to be turned off immediately to avoid causing further damage to the engine. 


Tech tip: always keep an eye on your engine temperature gauge. The worst thing you can do to your vehicle is let it run when the temperature gauge is above normal operating temperature.


Check Engine Light Diagnosis

Check engine lights throw codes that can be picked up by basic OBDII scanners available at your local auto parts store. However, basic scanners cannot pick up all the codes a more advanced, commercial-grade scanners can.


Professional auto repair shops such as Drive Nation Auto are equipped with the latest computers and software to get a comprehensive reading from the ECU, pinpoint the issue, and solve the problem from its root.
