What are common check engine light problems?
An illuminated check engine light doesn't automatically indicate that engine failure is imminent. Nevertheless, it's best to get to the shop ASAP so that the mechanic can conduct computerized diagnostics. This way, the problem can be accurately pinpointed and addressed before it escalates. At Preferred Automotive, our local mechanics can figure out what is triggering your check engine light and then expertly address the issue. Come and see if your check engine light has turned on.
Common Reason the Check Engine Light Turns On
A faulty catalytic converter is often the underlying issue that causes the check engine light to illuminate. Because your catalytic converter helps to reduce pollution, it's important that issues with it are quickly taken care of. With catalytic converter trouble, you may notice worsening acceleration, decreasing fuel-efficiency, and a sulphurous smell.
Faulty spark plugs can also trigger the light, and can cause difficulty starting your engine, as well as misfiring and rough idling. Bad ignition coils are another reason that the light may come on. An ignition coil problem can lead to poor acceleration, misfiring, and decreasing gas mileage.
Problems with certain sensors can also trigger the check engine light. A problem with an oxygen sensor can cause the light to flash on, and can cause a drop in MPGs, rough idling, and power loss. A faulty mass airflow sensor can also make the light illuminate, and can cause your engine to hesitate while accelerating.
It's also possible that all that's causing your light to turn on is a loose gas cap. If your gas cap is loose or missing, fuel can evaporate before you get the chance to use it, making it important that your cap is always fully secured after each time you fill up.
There are also some cases in which a faulty battery causes low voltage at the computer. This then causes the check engine light to illuminate.
