Check Engine Light Issues
The Check Engine or Service Engine Soon light is one of the more misunderstood of the dashboard lights. Your vehicle, with all its computer controls, is continually performing various self-tests to make sure the engine is running optimally while also giving off the least amount of pollutants in the exhaust. As you drive, the computer system will adjust the engine response to factors like speed, engine temperature, the mixture of fuel and air, to name a few. When the Check Engine light or Service Engine Soon light comes on, there’s something happening within the engine that is causing a problem with performance and emissions.
What causes the Service Engine Soon or Check Engine Light to come on?
In the simplest of explanations, this dashboard light comes on to alert you to a problem with the emissions. That means your vehicle isn’t running its best and it’s also polluting the environment. The important thing to know about the Service Engine Soon or Check Engine light is that it usually comes on at the first sign of a problem. That’s good because it means you can have it fixed before something more serious occurs.
When the Check Engine light comes on, you may wonder how quickly you need to have the situation addressed. While it’s not a major emergency, you should have the problem checked right away. If you wait, the engine will begin to run rougher and you will risk further damage to your vehicle’s emissions system. You may even end up having to replace the catalytic converter – an expensive job that could have been avoided if you dealt with the problem when the light firs came on.
Quite frequently, the Check Engine light comes on because of a loose or broken gas cap. The simplest way to find out if the gas cap is causing the problem is to make sure it is properly tightened or to replace the cap with one that is meant for your vehicle.
