4 Reasons Your Check Engine Light May Come On
The last thing you want to see while driving a long distance is an illuminated “check engine” light on your dashboard. While you should get it checked as soon as possible, you usually have a little time to get it into the shop; but the sooner, the better. Don’t let it go on too long and result in more repairs than may have been necessary if you’d had it checked out right away.
Here are a few reasons your “check engine” light could come on and what it might mean:
Your oxygen (O2) sensors need to be replaced – the oxygen sensor measures the amount of unburned oxygen in your car’s exhaust system. If you don’t address this issue, you’ll burn more fuel, which is costly these days. Faulty sensors could also damage other components like your spark plugs.
There is a problem with your gas cap – Gas caps help to seal the fuel system, maintaining pressure within the fuel tank and preventing fumes from leaking. A loose or cracked cap exposes the fuel system, and can cause a loss of fuel through evaporation.
Your catalytic converter needs to be replaced – catalytic converters help protect the environment by converting noxious carbon monoxide into less harmful compounds, such as carbon dioxide. If your catalytic converter needs to be replaced your vehicle will likely not pass an emissions test and you’ll have a loss of fuel economy.
Your spark plugs or plug wires need to be replaced – As the name implies, spark plugs provide the “spark” that’s responsible for initiating combustion in each engine cylinder. When not firing properly, you may notice a jolty engine. Good spark plugs can also help fuel economy and keep your engine running at maximum efficiency.
A blinking check engine light signifies that something is wrong somewhere. When the engine light is blinking, head to an auto repair shop as soon as possible – the symptom may require immediate attention.
The check engine light comes on to indicate a variety of potential problems with your car. The diagnostic reading we’ll get during your free check is checked against the code that triggered the light to turn one. The code indicates there’s a problem on a particular circuit, but not necessarily that there’s a problem with a part. Get to Ideal Automotive and we’ll diagnose the problem and get it fixed as quickly and efficiently as possible, and we won’t sell you parts you don’t need.
