Watching Your Check Engine Light

Posted December 25, 2016 1:59 AM

Did you know that most of the cars driving around Suwanee, GA, carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969?

New cars sold in the Suwanee area have as many as 12 networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, auto computers have been controlling about 85 percent of your vehicle's functions.

Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do Suwanee drivers know when there is a problem?

It's simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores a trouble code in the computer.

It can be pretty disturbing for Suwanee drivers when the Check Engine light comes on. We wonder just how urgent it is. Generally speaking, it is not critical like a temperature or oil pressure light. When you get one of those it means STOP NOW! When the Check Engine light shows up, you should come in to D.C. Auto in Suwanee to find out what the matter is as soon as possible.

Since 1996, there has been a strong emissions control component to the Check Engine diagnostic. But if your Check Engine light flashes on and off, you know that it is more urgent and you need to get it checked immediately to prevent damage. You should slow down and avoid towing or heavy loads until you can get it checked out.

Your friendly and knowledgeable technicians at D.C. Auto have special diagnostic equipment that will retrieve the trouble code from the computer and help him determine what is wrong. From there, we can fix it and get you back on the road.

Stop by if you're Check Engine light is on.

I'm new to Georgia and my car broke down on Saturday. Dave answered my call and instantly put my mind at ease. He's very professional and kind, two traits that mechanics Usually lack!! I was so pleasantly surprised and come to find out he is who all my coworkers would have recommended! I just happened across D.C.Auto through a last minute google search! He is so highly regarded in this community, I'm so thankful to have found this company!!the owner Ron greeted me when I can in to pay for my repairs. VERY REASONABLE price. And so friendly and kind. Needles to say this is where I'll go whenever I need anything done on my car.

I am a 76 yr old long-standing customer of D. C. Auto Atlanta. Yesterday, I took my 2014 Nissan in for a 90,000 mile maintenance. I was given an estimate. When I returned today, the bill was $65 less. They do great work, are very ethical and can certainly be trusted. I highly recommend them to my Senior Apartment Residents!
