The check engine light never goes off: The onboard diagnostic system of your car has identified a problem that needs to be rectified.
The check engine light may be illuminated or blink depending on your vehicle’s make and model.
Reasons for Checking Your Vehicle Possible Engine Light On
The check engine light on your car may have come on for a number of different reasons. Some of the most frequent reasons for your check engine light to illuminate are listed below:
- Gas cap that is loose, broken, or missing. The gas lid keeps fuel from evaporating out of the tank. In order to maintain pressure, it also seals the gasoline tank. If the check engine light comes on, one of the first things you should look for is the gas cap. Ensure that it is safe.
- defective head gasket. The cylinder heads and engine block are separated by the head gaskets. If the head gasket on your car has ruptured, there may be an oil or coolant leak, or the coolant and oil may be mixing.
- Oxygen sensor damage. The oxygen sensor gauges the amount of oxygen in the exhaust system of your car. This will decrease the fuel efficiency of your car if there is too much oxygen in the exhaust system due to a failure. It can affect your car’s catalytic converter or spark plugs if it isn’t replaced.
- defective spark plugs. Spark plugs are essential to the operation of your car’s engine. Your car’s performance and power will be considerably worse and diminished if you have damaged spark plugs or spark plug wires, and the engine may even be unable to start. If defective spark plugs are not replaced when necessary, further car problems may result.
- Transmitter problems. To provide the wheels the power they need to go at a certain speed, the transmission of the car changes gears. You can notice vibrations and/or accelerating concerns if your car’s transmission isn’t working properly. When you suspect problems with the transmission, you should have it repaired right away because it is an expensive repair. This will guarantee your on-road security.
- Dead or low battery. Your car’s battery is essential for starting it. Your car can start slowly or not at all if the battery is low or dead. It can be jump-started, but it’s wise to get a dead battery changed so you aren’t left stuck.
