Reasons Your Check Engine Light Is On
You may find yourself thinking, ‘That was silly,’ when the light is on for something simple – but when it’s something bigger, you’ll be happy that it gave you a warning.
- 1. Loose or Faulty Gas Cap
One of the most common causes is that if the cap is loose, cracked, or missing, it can trigger the light due to fuel system pressure loss. Sometimes, you are just in a hurry, and that cap can be loose, and you’ll see that light pop up. - 2. Faulty Oxygen Sensor
The O2 sensor monitors exhaust gases. If it fails, it can affect fuel efficiency and emissions. You’ll start seeing your fuel mileage drop, and you’ll find yourself at the gas station more often. - 3. Malfunctioning Catalytic Converter
This part reduces harmful emissions. A failing catalytic converter can cause poor performance and increased pollution. - 4. Bad Spark Plugs or Ignition Coils
Worn spark plugs or faulty coils can cause misfires, reduced power, and fuel inefficiency. You want to have your spark plugs and coils checked on a regular basis for wear and tear. - 5. Mass Airflow Sensor Issues
This sensor controls how much air enters the engine. If it’s dirty or malfunctioning, it can cause poor acceleration and stalling. - 6. Faulty EVAP System Components
The evaporative emissions system controls fuel vapors. A leak or failed part can trigger the light. - 7. Engine Misfires
Misfires can be caused by fuel delivery issues, spark problems, or sensor malfunctions. They usually affect drivability and make it not so fun to be behind the wheel. - 8. Transmission Problems
Some transmission issues can cause the check engine light to appear, especially if they’re affecting engine performance. - 9. Failing Battery or Charging System
Low voltage or charging problems can sometimes trigger warning lights, including the check engine light. - 10. Sensor or Wiring Problems
A faulty sensor or even a loose wire connection can confuse the computer and cause the light to come on.
