Chevrolet Check Engine Light Diagnosis Service

Certified Chevrolet Check Engine Light Diagnosis in Monrovia, CA

Chevrolet vehicles are among the heartiest of vehicles on the road today, but even the best vehicles need care. One way that your Chevrolet can communicate to you that it needs that care is through the check engine light, which turns on when the car’s computer determines that there’s a need to take a look at the fuel system. At our service center at Sierra Chevrolet of Monrovia, we provide certified check engine light diagnosis so that you can get to the bottom of what needs to be done for your Chevrolet.

Why Check Engine Lights Turn On

Your Chevrolet is full of sensors that monitor various aspects of your car’s performance. Many of these sensors reside in your car’s fuel system, which includes everything in between your exhaust pipe and your fuel tank. When a sensor takes an abnormal reading, it generates a code that specifies the abnormal reading and where it came from, then it sends that code to the computer. The computer logs the code and then turns on the check engine light so that you can quickly address the abnormal reading and its cause in your Chevrolet.

How We Diagnose Check Engine Lights

There’s a simple process of elimination involved in check engine light diagnosis. Our technicians start by pulling the code from the car’s computer and checking to see what sensor got an abnormal reading and where. From there, they can delve into your car’s inner workings and look at all the possible causes of that abnormal reading. One by one, they eliminate causes through testing and inspection, and when they finally find the true cause, they can finally let you know what’s going on. From there, you can discuss and implement strategies to fix the problem with your Chevrolet as soon as possible.
