What are common check engine light triggers?
If your check engine light turns on, it doesn't automatically indicate that your engine is on the brink of disaster. Nonetheless, you'll want to promptly visit the shop for computerized diagnostics so the issue can be pinpointed before it escalates and becomes more expensive to address. At The Car Doctor, our local mechanics are experts at diagnosing engine problems. Then, once the issue has been identified, we'll get right to work on the repairs so you can get back on the road in as little time as possible.
Common Problems that Trigger the Check Engine Light
Oftentimes, the check engine light comes on due to problems with the catalytic converter. Symptoms of a faulty catalytic converter include worsening gas mileage, poor acceleration, and an odor similar to rotten eggs. To ensure your car isn't overly polluting, you need to be driving with a healthy catalytic converter. A malfunctioning O2 sensor can also trigger your check engine light and may cause issues with your catalytic converter. The mass airflow sensor is another sensor that triggers your check engine light if there's a problem with it. One sign of MAF sensor trouble is that your engine stalls shortly after you fire it up.
A bad battery can also trigger the check engine light if it's causing low voltage at the computer. Faulty spark plugs are another potential culprit when the light illuminates. Cars made in the last twenty years can often go 100,000 miles before they need new plugs, while older vehicles tend to need plug replacement more regularly. The check engine light might also turn on because of bad ignition coils. With an ignition coil issue, you could see a drop in MPGs, and may have trouble getting your engine to start. A more peculiar reason that your check engine light could come on is if your gas cap is loose. It's important that your gas cap stays securely fastened so that fuel doesn't evaporate before you get the chance to use it.
