Check Engine Indicator Light Turns On

6 Trivial Things Cause The Check Engine Indicator Light Turns On

Check Engine Indicator Light Turns On, Again driving suddenly the check engine indicator on the instrument panel lights up, don’t panic yet. fix Engine Indicator Light Check Turns On, Here it is the cause and solution of the check engine indicator lights up.

Who does not panic when he is relaxed driving but suddenly the engine check indicator on the instrument panel lights up? Steps taken, usually the driver will automatically pull the car to a safe place, and open the hood while asking “why is this my car?”.

Though not necessarily the problem of the engine check indicator that lights up behind the hood or something related to the engine of your car.

Unless your car does indeed experience symptoms such as continuous brebet, or limping engine. Better not be forced, immediately call a crane and visit the nearest workshop.

The engine check indicator does not always inform you of fatal engine or electronic system damage. Usually the engine check indicator lights appear when the car is on stand by, and will turn off when the car is turned on.

However, if the check engine indicator lights still blink when the car is started, there are several causes. It could be due to sagging sockets, water intake, leakage on the radiator, broken cable, sensor failure, or even the ECU has suffered a little damage. But it can also be caused by other components not being installed correctly.

Cause and Solution Check Engine Indicator Light Turns On

Gasoline Cap Not Meeting

Gasoline Cap Not Meeting

Fuel caps that are open or not tightly closed by the sensor on the ECU are considered to be dangerous for those in the car or the surrounding environment. Evaporation of the fuel can cause fires and be fatal.

If the check engine indicator lights up, but you don’t feel anything wrong with the car, this could be the fuel tank cover. Stop driving immediately, tighten the fuel tank cover, and check for leaks.

Dirty Air Filters

Dirty Air Filters

In addition to the fuel tank cap that is not completely closed or not tightly closed, the engine check indicator will also turn on if the air filter is dirty or needs to be replaced.

This air filter is closely related to the mass airflow sensor which serves to determine the amount of fuel that must be used based on the air entering the car engine. If the air filter is too dirty, dust or dirt from outside can enter and inhibit the supply of air entering the combustion chamber.

The majority of damaged mass airflow sensors are caused by improper air filter installation, the air filter is too dirty, or it needs to be replaced. Ideally, air filters are cleaned every 10,000 kilometers and must be replaced every 40,000 kilometers. However, there are also some cars that require air filter replacement faster than that distance due to external or environmental factors.

Actually you can still drive for several months even though the mass airflow sensor is broken, but the engine will lose power and fuel quickly wasteful.

Oxygen Sensor Does Not Work

Oxygen Sensor Does Not Work

This component serves to monitor oxygen in the exhaust and determine the amount of fuel burned. If the oxygen sensor (O2) is damaged or does not work properly, it can interfere with engine performance and damage the catalytic converter.

Generally, the problem is caused by the closure of the oxygen sensor by oil from time to time thereby reducing the sensor’s ability to process oxygen and fuel.

Catalytic converter

Catalytic converters are able to convert carbon monoxide and other harmful substances into compounds that are safe for the environment.

One of the signs if the catalytic converter is damaged is that the fuel runs out faster or the car does not have the power to drive even the gas pedal is trodden deeply, other than the amount of unstable exhaust gas.

You do not need to worry about this if you have routine service. Another cause could be due to a defective oxygen sensor so the catalytic convertor could not carry out the conversion process.

Spark plugs and wires

This one is indeed small, but if it has problems, it has a big effect on the car’s performance. The performance of spark plugs that are disturbed can make fuel consumption in the car become more wasteful due to less optimal combustion in the engine room. The job of the spark plug is the one that ignites the fire so that combustion in the engine room can run.

In addition, spark plug wires that have started to brittle or not installed properly will reduce combustion and spark plug performance.

Therefore, for more complete combustion and suddenly the check engine indicator lights up, it is recommended that you check the spark plug and the cable. If it is dirty, can be cleaned, but it is more optimal to replace it with a new one. Spark plug replacement is usually done at a distance of 20,000 kilometers.

Check battery

Check battery

The last attempt when the check engine light is on is to check the battery. You can disconnect the negative connector cable in the battery and then wait for three seconds. If you have reinserted the negative connector cable in the camp.

If it has been done but the engine check indicator lights are still on, there may be damage to your car’s sensor. This method is only to find out what sensors are experiencing problems or damage. If found, immediately take your car to an authorized repair shop to repair or replace the damaged sensor.

So, next time if the check engine indicator light on the instrument panel turns on, don’t panic yet. Just check the parts mentioned above. But always remember the saying is better to prevent than cure. It is better to be diligent in regular service than the check engine indicator lights go on.
