It’s important to take the check engine light seriously because a recent study proved how effective and accurate it is. This light turns on when there is a problem with your automobile that is not covered by another light or gauge. HCS Auto Repair can run a diagnostic test to find out why your check engine light is on. Here are common car problems that turn on the check engine light.
Clogged Catalytic Converter
Your catalytic converter is part of the exhaust system. It treats exhaust to make it safer to be released into the environment. The catalytic converter has a long lifespan, about 10 years to be exact. It will clog or malfunction eventually, however, and when it does, the check engine light will turn on.
Faulty EVAP Control System
The EVAP control system is a system that is designed to make certain diesel fuel or gasoline does not evaporate from your automobile into the environment. If this system goes bad, you may experience engine performance problems along with receiving a check engine warning on the dashboard.
Loose Gas Tank Cap
Another thing that prevents fuel from evaporating into the environment is your gas tank cap. If your check engine light comes on right after you fill your automobile, it’s possible that you did not tighten the gas cap tight enough. Check to make sure it is secured. If it is, there is another problem with your vehicle.
Malfunctioning MAF Sensor
Your car, truck, or utility vehicle is also likely equipped with a mass airflow sensor. This part can last the life of your automobile if you take care of your automobile. If the MAF sensor malfunctions, however, it will indirectly skew the balance of air and fuel in the combustion chamber and turn on the check engine light to warn you of trouble.
Malfunctioning O2 Sensor
The oxygen sensor has an average lifespan of 90,000 miles. In many cases, you will get more mileage out of the O2 sensor. This being said, it is a common reason why the check engine light turns on. If it starts to go bad and malfunctions, the engine control module will flip on the check engine light.
Worn Spark Plugs or Wires
Finally, spark plugs and spark plug wires can cause firing problems in the engine if they are worn out. You will feel your engine sputtering, and, in severe cases, your engine will stall. You will also receive a check engine warning.
