5 Reasons Why Check Engine Is On

5 Reasons Why Check Engine Is On – Just got home and parked the car in the garage, suddenly the car’s check engine indicator flashed. Have you experienced something similar, Nissan Lovers? Actually, you can check for yourself why the car’s check engine indicator is on. Here are five reasons you can know.

5 Reasons Why Check Engine Is On

There are at least five reasons why the check engine on the dashboard can turn on. Here is the reason.

Why Check Engine Is On
One of the problems that cause the check engine to turn on is the MAF sensor that is damaged.

Mass Airflow Sensor

Mass airflow sensor serves to determine the amount of fuel that must be used based on the air entering the car engine. If damaged, the mass airflow sensor can result in an increase in fuel emissions so that the system’s economy can drop. The majority of damaged mass airflow sensors are caused by improper installation of the air filter or never being replaced. Ideally, you should replace the air filter regularly once a year. Actually, you can still drive for several months even if the mass airflow sensor is damaged, but the fuel will run out faster.

Fuel Tank Cover Not Tight

During this time, you may think of the fuel tank cover as a thing that is not too important. In fact, if it is damaged or not completely closed, this can cause fuel evaporation and harm the environment around you. If the check engine indicator lights up, but you don’t feel anything wrong with the car, it could be that the fuel tank cover is the cause. Stop driving immediately, tighten the fuel tank cover, and check for leaks.

Oxygen Sensor

The oxygen sensor on the car is used to monitor the unburned oxygen in the exhaust. This section can help you figure out how much fuel you’re burning. A malfunctioning sensor should indicate that it is not providing the correct data to the computer and causing a decrease in fuel consumption. Generally, the problem is caused by the oxygen sensor being covered by the oil over time thereby reducing the sensor’s ability to treat oxygen and fuel.

Emission Evaporation Purge Control Valve

The purge control valve is part of the car’s evaporative emission system (EVAP). When the engine is running or running and is in a warm condition, the engine computer will gradually open the purge valve so that some of the fuel vapor can move from the charcoal canister to be burned in the engine. Well, if this cleaning flow is not read ideally, then the check engine indicator on your car will light up.

Catalytic Converter

Part of the engine one serves to reduce wasted gas. Catalytic converters are capable of converting carbon monoxide and other harmful substances into harmless compounds. One of the signs of damage to the catalytic converter is that the fuel runs out faster or your car doesn’t run as fast as usual when you step on the gas pedal. However, you don’t have to worry about this happening if you’ve been doing regular servicing. Another cause could be a faulty oxygen sensor so that the catalytic converter cannot carry out the conversion process.

So, you don’t need to panic right away if suddenly the check engine indicator on your car lights up. If you drive a Nissan Evalia, you will be greatly helped because this car is equipped with a Multi-Information Display feature that can help you show information about the condition of the car.
