If you are a Cruze owner, when the engine fault light on your vehicle starts to light up, it will definitely make you suspicious. This is a way to inform you that there is a problem with the vehicle, but what is the problem? Today, we will explain in detail the reason why the engine fault light is on and explore some possible solutions. What is the engine fault light?The engine fault light is sometimes also called "check engine light". This is a warning light on the vehicle dashboard, which will light up when the vehicle's electronic control module (ECM) detects the failure of the engine or emission system. Once it lights up, it will always stay on until the problem is fixed or the fault code in the vehicle system has been cleared. For most car owners, the lighting of the engine fault light may be a disturbing problem. But in fact, a failure light like this does not necessarily mean that there is a serious problem with the vehicle. As we are going to talk about next, there are many kinds of lights that may cause the engine fault light to turn on. Problems that the engine fault light may indicate. The engine fault light can issue a series of warnings, including engine wear, overheating, oxygen sensor failure in the engine, vehicle battery problems, and possibly more serious engine failures.The following are some typical reasons that may cause your Cruze engine failure light to light up: 1. Spark plug problem The work of the spark plug is started when the car engine burns and ignites. Usually, spark plugs need to be replaced regularly. If there is a problem with your spark plug, your vehicle may feel heavy, the power will decrease, the single cylinder will catch fire, and the fuel economy will decrease, which may cause the engine fault light to turn on. Two. Atmospheric pressure sensor problem Atmospheric pressure sensor is responsible for conveying information such as meteorological changes, altitude, temperature and humidity to the ECU. If the atmospheric pressure sensor fails, it may send the wrong signal to the ECU, causing the engine fault light to light up. 3. Oxygen sensor problem Oxygen sensor is one of the key components of the automobile emission system.Its job is to monitor the oxygen level in the engine discharge to ensure that the emission concentration meets the regulatory requirements. If there is a problem with your oxygen sensor, your vehicle may have problems such as performance degradation and fuel economy, which may also cause the engine fault light to turn on. Four. Fuel lock If your engine system has a fuel lock problem, your vehicle will not be able to start, and the engine fault light will also turn on. Fuel locking is rare, but when it happens, we recommend that you immediately send the car to the repair shop for repair. The above problems are just a few possible cases when your engine fault light turns on. If you find that the engine fault light on your vehicle is always on, we recommend that you go to the repair center for inspection or consultation with a professional technician immediately.How to fix the engine fault light problem If your engine fault light is on, we strongly recommend that you take some basic corrective measures to avoid more serious damage. First of all, you should stop your vehicle and check the level of engine oil. If you find that the amount of oil is insufficient, you need to add enough oil and check whether there is any problem with the oil pump, oil filter and oil pipe. Secondly, you should carefully check whether your car battery is normal and whether the wires are damaged. You can also check whether your car's exhaust pipe, exhaust system and oxygen sensor are working properly. If you think the above problems are not the cause of the engine fault light, then you need to send the car to a professional repair shop for inspection. The technical experts of the repair shop can help you diagnose the problem and find the corresponding solution to ensure that your vehicle is back in optimal condition.To sum up, the engine fault light may be an indicator light with a problem in your vehicle.
