Check Engine Light

Serving Plano, Texas and surrounding areas

Most of us have had that experience of driving down the road, looking down at our dashboard and seeing our “Check Engine” light on. It’s a frustrating feeling because we never really know what is causing the light to come on out of nowhere, and we aren’t sure if we should seek help immediately or put it off (hoping it just magically goes off—as it sometimes does!).

If your “Check Engine” light comes on and stays on, there is a very good chance that something is amiss, but it can be very minor such as your gas cap not being tight enough. However, it can also be a sign that something much more serious is wrong with your car. For this reason, when your “Check Engine” light does come on, you should have it checked out by the highly skilled certified technicians at AAMCO in Plano, Texas.

This is why you need our help—the team at AAMCO Transmission and Automotive Repair of Plano is trained to use the most advanced diagnostic equipment in the industry to pinpoint the specific problem that is causing your “Check Engine” light to stay on. And we’ll figure out the problem at no cost to you. Just give us a call, stop by or schedule an appointment right here on our website, and we’ll make sure that light goes off and stays off for good.

What Do the “Check Engine” or “Service Engine Soon” Light Mean?

Modern cars, trucks, vans and SUV’s are engineered to run with a very precise tune to ensure maximum fuel efficiency and minimum emissions. When your car’s onboard computer senses that your car is no longer running within this tune, your “Check Engine” light will come on. It’s AAMCO’s job to figure out why it’s on and fix it. To achieve this, we will perform a free diagnostic inspection to find out what caused the light to come on. We do this by hooking your car up to our computer to identify the problem; this allows us to give you an indication of what may be causing the problem. However, to determine the specific cause of the light staying on, an extensive diagnostic inspection is often required, and this is not free.

Some of the most common culprits for triggering your “Check Engine” light include:

  • Air flow problems, which will lead to a decrease in power
  • System running too lean, which may cause either a hesitation or surge during acceleration
  • System running too rich, which may cause misfires
  • Cylinder misfires
  • Catalyst system efficiency is below threshold, which can damage your exhaust system

Because so many problems can cause the “Check Engine” light to come on, it takes skilled technicians to diagnose this problem. The experts at AAMCO in Plano, Texas have a great deal of experience with check engine light issues, so please schedule an appointment right here on our website, call us or stop by to have this checked out as soon as you can.
