GM Check Engine Light Diagnosis

Certified Chevy Buick GMC Check Engine Light Diagnosis in Castle Rock, CO

Your check engine light is one of the main ways to know if something is wrong with your engine. It lights up when there’s an issue that needs to be resolved, and that tells you that it’s time to get to the service center. If it lights up and flashes, that means you need to pull over and get a tow immediately, as that indicates imminent damage to your engine. Otherwise, you can come to our service center at Castle Rock Chevy Buick GMC when you have time, and we’ll help you figure out what’s going on.

What Causes Check Engine Lights to Turn On

The check engine light is connected to the computer, and the computer receives signals from sensors all around the car. Many of these sensors are located in and around the fuel system, which includes everything starting from the fuel tank and going through to the exhaust pipe. When one of these sensors notices an abnormality, it sends a code to the computer saying what the abnormal reading was. The computer logs the code and then lights the check engine light for you to take care of it.

How We Diagnose Check Engine Lights

When our technicians take care of your check engine light diagnosis, the first thing they do is check to see what code the computer logged. That gives them an idea of where the problem was, what sorts of things could have caused it, and where to look in the car. From there, they find all the possible causes of that abnormal reading and rule them out until they find the one that’s happening in your fuel line.
