What is the check engine light?

A check engine light is often known as a malfunction indicator lamp (MIL). The engine light is an indication that the onboard diagnostics system, also known as OBD II, identifies a problem with the vehicle’s emissions, ignition, fuel, or any other system trouble.

Actually, a fault in a car is signaled by a computerized engine-management system. You shouldn’t ignore the flashing light if there’s a problem, since doing so might eventually cause the entire automobile system to fail.

How does check engine light system work?

Generally, all input signals that have an impact on outflow are monitored by the car’s computer. The computer activates Check Engine Light if any of the monitored signals depart from the restrictions set by the government.

Whenever the system in the automobile thinks there’s a problem with the emissions control unit that might impact it, it will show a check engine yellow light turning on. Additionally, one or more diagnostic fault codes are saved in the car’s computer when the light turns on.

Why is my check engine light on in 2017 Chevy Cruze?

If you find out the car is flashing, the most common causes are a loose gas cap, a malfunctioning oxygen sensor, a broken catalytic converter, a faulty head gasket, fuel injection system issues, a filthy mass airflow sensor, or worn spark plugs.

The most frequent problem among them is a defective oxygen sensor, which consistently indicates a check engine signal. However, an issue that needs attention is indicated by a blinking light, or you will notice a red light instead of a yellow or orange light.

How do you identify the cause of an engine failure?

Check the dashboard gauges or lights for indications of low pressure of oil or overheating to identify the Chevy Cruze’s problems. For example, the car’s check engine light started flashing, and now it won’t drive past first or second gear even though it revs very high and you can only travel 15 to 30 mph. This uncovers the issues with your car. Besides, you should give us a check on some other issues that we are going to discuss now.

The indicator is blinking or flashing

You can ensure the engine failure by checking that the car’s indicator is flashing light and blinking frequently. A blinking light is a critical problem that requires a solution. It is taking place as a result of the engine misfiring badly. This might cause unburned gas to leak into the exhaust system, and overheating the converter makes it damaged.

In order to get a mechanic to make a diagnosis, take the car slowly to park near the mechanic’s shop. But keep in mind that you’re probably going to do serious damage if you keep driving in that circumstance.

Bad oxygen sensor

The most frequent issue is a faulty oxygen sensor. An oxygen sensor, which also determines the ideal air-to-fuel ratio and the engine’s efficiency, looks for unburned oxygen in the output. The computer is unable to acquire accurate data because of the issue with this sensor.

The corrosion of the metals inside has an impact on the oxygen sensor’s capacity to produce an accurate reading. In addition to harming the catalytic converter, it will eventually increase fuel consumption. However, calling a technician to get a precise diagnosis is the best plan of action.

Damaged or loose gas cap

Your gas cap keeps the pressure in your fuel tank constant and serves as a seal for your fuel system. If the light is on, the gas cap might be loose or damaged. This allows for air to enter this place. It is easily corrected by stopping, adjusting the gas cap, or, if it’s broken, replacing it.

Broken catalytic converter

Catalytic converters help in the emission reduction of exhaust gases. Carbon monoxide and other environmentally hazardous gases are changed into less dangerous pollutants. The engine light on your car lets us know about another issue called converter failure.

They are actually related, and the misfire and oxygen sensor problems will ultimately damage the catalytic converter. When you press harder on the gas pedal, your car won’t move any faster, which is another sign that it is harming gas mileage. Therefore, you need to change the broken converter.

A faulty mass airflow sensor

Another critical feature is the airflow sensor, which regulates the fuel supply according to the airflow through the engine. Ultimately, you will notice the car will stall, run slower, the pollutants will increase, and your gas mileage will decrease because of a faulty air flow detector.

When it is not installed correctly or has been a long time since it was replaced, the car generally triggers. You should change the airflow sensor every year. Even though you can still drive the car with this problem, it is better to call a professional mechanic so they can diagnose the sensor and fix it.

Faulty spark plugs or wires

A spark plug covers the combustion chamber and produces the gap for the spark to ignite the fuel in the engine. Your engine might misfire due to faulty spark plugs, which might also turn on the engine light.

Once spark plugs are not functioning correctly, your car’s engine yellow light will remain activated. As a result, you can fix or replace it by getting professional assistance.

Dead battery

Your car will run into problems for the first time ever because of a battery issue! You might also forget to install the battery properly. You might notice a low voltage that indicates a deteriorating or dying automobile battery.

Low voltage is also reaching the computer in your automobile, which is in charge of reporting fault codes. The Check Engine Light or even the Battery Charge Warning Light will activate as a result of an error code being issued. Make sure you fix the battery fault as soon as possible.
