7 Reasons Why Your Check Engine Light Might Be On

If the check engine light is on, it means that something has caused a lot of trouble and is in need of service. The car will probably be speeding or have some other problem that you cannot troubleshoot. It is a signal from the computer that the car has a problem and needs maintenance or repair. Get your car serviced. A preventative maintenance service can clear up the issue and save you money. Here are seven reasons for check engine light on.

1. The Gas Cap Is Not Secure

The gas cap is an important security measure and should be secure enough to avoid outside access. If the gas cap is not secured correctly, air can enter your engine and cause damage. Your mechanic will need to replace the gas cap or secure the one you have.

2. The Air Filter Is Clogged or Dirty

Replace air filters regularly to prevent dirt and debris from entering your engine and causing damage. If your vehicle has a fuel-injected engine, make sure you have a new clean air filter installed each time you have an oil change or service performed at the dealership, as these filters need to be replaced every 30,000 miles or two years (depending on your state).

3. The Spark Plugs Are Dirty or Need Replacing

A spark plug with carbon deposits is less efficient in delivering fuel to the cylinders during combustion, which causes poor performance and higher emissions levels for your vehicle. Take the vehicle to a local auto repair shop for an inspection.

4. The Engine Was Overheated, and Overheating Can Cause Damage

Overheating can cause damage to the engine, transmission, exhaust system and other parts of your car. If you notice that your car has been overheating, make sure you have it checked by a professional as soon as possible.

5. Your Battery Is Weak or Dead

If your car has a weak or dead battery, it will not be able to start when you need it most. This will often result in stranded drivers and passengers who have no way of getting home or even of reaching a safe place until they are towed by a professional. When replacing batteries, make sure they are new or at least have an extended warranty on them so that if something should go wrong with them during the replacement process, you are covered for the full replacement cost (not just for labor).

6. Your Engine Is Missing Parts or Has Other Mechanical Problems

If your engine is missing parts, it can cause your vehicle to run poorly and may also be a safety hazard for vehicle occupants and the driver. If your car has other mechanical problems, it will not be able to run correctly and may also result in unsafe driving conditions for you and others on the road.

7. Your Car Was Manufactured With a Defect That Is Causing Problems

If you have a car manufactured with an issue (such as a faulty transmission) that has caused issues over time, it is time to replace it. These defects are rare but can cause serious accidents when they happen. They can even be life-threatening, especially if you are driving in wet weather or on icy roads when there’s ice covering the roads. If you have a car experiencing issues due to a manufacturing defect, make sure to have it replaced.
