5 Causes of Car Injection Indicator Light Staying On
On the dashboard of a car, it is usually equipped with various indicator lights, ranging from the speedometer, turn signals, including the injection light or check engine. Usually, the illumination of the check engine light brings a certain panic to car owners. Because, it can be a sign of something specific. Let's recognize the causes of the injection indicator light continuously illuminating in the car.
Here Are the Causes of the Injection Indicator Light Continuously Illuminating
The indicator light on the car needs to be paid attention to by all car owners. If you do not realize that there is damage to the car components, it is possible that other car components will also be damaged.
Therefore, you must know the causes of car components if there are problems. One of them is the indicator light component on the injection car.
The cause of the injection indicator light continuously illuminating in the car is partly due to the air filter. However, there are other causes, namely:
1. Loose Fuel Cap
The illumination of the car's injection indicator light will certainly cause panic for the driver, especially if the driver is still inexperienced.
This condition is normal, as the illuminated indicator light can serve as an early warning for the driver regarding a disturbance in the vehicle's engine.
However, you do not need to worry immediately when the check engine indicator lights up. Because, it may not be a problem with the engine, but due to a fuel cap that is not tightly closed.
You should know that this trivial matter will be read by the ECU sensor as a dangerous condition. Therefore, immediately check the condition of the fuel cap and tighten it if it feels like it is not closing properly.
2. Problems with the Air Filter
The cause of the injection indicator light continuously illuminating in the car can also occur due to problems with the air filter. Usually, this condition is related to a dirty air filter or one that needs to be replaced.
As is known, the air filter is closely related to the mass air flow sensor. Where, this sensor plays a role in determining the fuel used.
If the air filter is too dirty, it can cause dust and dirt from outside to enter, thus obstructing the air supply into the car's fuel chamber.
This condition will cause the mass air flow sensor to not work properly, which ultimately causes the indicator light on the check engine to continuously illuminate.

3. Damage to the Oxygen Sensor
When this sensor component experiences damage, it will indirectly affect engine performance and damage the catalytic converter.
Usually, this condition can occur because the oxygen sensor is covered by oil, thus reducing its ability to process oxygen. This condition can be a cause of the injection indicator light continuously illuminating in the car.
4. Problems with the Catalytic Converter
Damage to the oxygen sensor can also cause problems with the catalytic converter. The signs of damage to the catalytic converter component are rapid fuel depletion or a lack of power in the car to accelerate even when the gas pedal is pressed deeply.
Therefore, always pay attention to the condition of this component so that the indicator does not light up.
5. Battery Condition Needs Checking
Another step you need to take when you find the check engine indicator light on is to check the car battery.
In this case, you can disconnect the cable on the negative battery connector for a few seconds, then reconnect the cable.
Usually, the battery can be the cause of the injection indicator light continuously illuminating in the car.
Those are some factors that can cause the injection indicator light to continuously illuminate. If this condition is experienced by your car, it is advisable to check some of these components.
If no problems are found with other small components, it is best to take the vehicle to a trusted workshop for maintenance.
