Different Things the Light Can Mean
The ‘Check Engine’ light can indicate many issues, from simple fixes to more serious repairs. A loose or defective gas cap is a common culprit, especially if the cap is not tightened properly—that alone can cause the light to turn on.
It might be a faulty oxygen sensor, which tracks unburned oxygen in the exhaust. Malfunctioning in this sensor can also lead to decreased fuel efficiency and increased emissions. A problem with the catalytic converter can also trigger the light. Since the catalytic converter reduces harmful emissions, a broken one can mean less performance and lower fuel economy.
Defective spark plugs or ignition coils may lead to engine misfires, causing your vehicle to jerk and triggering the warning light. Or it could be a faulty mass airflow sensor, which measures the amount of air entering the engine, and that negatively impacts overall performance.
You may also find that the ‘Check Engine’ light comes on with other warning lights, such as when the temperature warning. This combination may point to more serious problems, such as engine overheating, that require you to stop driving as soon as possible.
The 'First Aid' of the 'Check Engine' Light
- When on a trip, the first thing to do if the ‘Check Engine’ light appears is not to panic and evaluate the current scenario. Pay attention to how your vehicle is driving—does it feel different? Is there anything strange coming out of the car?
- Next, pull over safely and also check the gas cap to ensure it’s properly tightened. A loose gas cap can occasionally set the light off, and if that’s the issue, it might take a few drives for the system to reset.
- If the vehicle appears to be functioning fine, it’s best to slow down and refrain from heavy-duty accelerating that could potentially cause further damage until you’re able to have it looked at.
- Do not give in to the urge to diagnose or repair it yourself; modern vehicles are complicated, and halfhearted repairs can lead to larger issues.
- Make an appointment with a trusted auto repair shop as soon as you can. Putting off a professional inspection can escalate a small problem into an expensive repair.
