How Many Reasons Are There for the Engine Fault Light?

There are mainly 7 reasons for the engine fault light to illuminate: Sensor malfunction: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine fault light to illuminate. Fuel quality issues: If fuel and engine oil are not added as required by the manufacturer, it may cause engine wear and trigger the fault light. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon deposits or knocking. When detected by the oxygen sensor and reported to the ECU, the fault light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pump, or clogged fuel lines can cause poor combustion of the air-fuel mixture. Turbocharging problems: The intake turbocharging pipeline or turbocharger can also cause the engine fault light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms like oil leakage, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake problems: If the car's intake system malfunctions, it may lead to clogged engine pipelines, and in severe cases, the engine fault light will illuminate. A dirty or uncleaned air filter can cause intake issues. Exhaust problems: Exhaust faults can also trigger the engine fault light. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings, with the catalytic converter being the most frequent issue. Using leaded gasoline, lead- or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily cause catalytic converter failure. Anti-theft system malfunction: If the car's electronic anti-theft system fails or the anti-theft controller does not match the engine ECU, the anti-theft system can prevent the engine from operating normally and illuminate the fault light. If the engine fault light is on, follow these steps: First, check if the engine is running normally. Look for issues like shaking or black smoke. If present, avoid restarting the engine. Note: Do not restart if the red light is on. If the engine can start, turn it off for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'ON' position (without depressing the clutch). The car will perform a self-check after powering on. Wait 5-10 seconds to see if the fault light turns off. If the light remains on, visit a service station as soon as possible. Technicians can use a portable diagnostic tool to read fault codes, identify the issue, and perform targeted repairs.

What to Do When the Car Windshield Fogs Up on Rainy Days?

Press the defog button, turn on the air conditioning (A/C) switch, set the temperature to the lowest, and switch to external circulation to defog. Both cold and warm air can be used to defog the car windows, but warm air is slower than cold air. The most effective method is to use cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing on the glass and achieving the purpose of defogging. The method for using warm air to defog is the same as using cold air, but it should be noted that warm air should not be used for defogging on rainy days, as it will initially worsen the fog. When the car windows fog up, external circulation should be used. The reason for car window fogging: There is a certain temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the surface with the lower temperature will have a lower saturated vapor pressure than the surrounding environment, causing water vapor to gather on the glass surface and form tiny water droplets, resulting in fog. Methods to defog car windows: Air Conditioning Cooling: Use the air conditioning's cooling and dehumidifying function to reduce air humidity and remove fog. In summer, especially when many people enter the car and the air conditioning is not turned on in time, the high humidity of exhaled air can quickly cause the windshield to fog up. In this case, turn on the air conditioning to blow cold air onto the windshield. Using the air conditioning's dehumidifying function, the fog on the windshield can be removed quickly. However, if the humidity is too high and the air conditioning is not effective, slightly open the window to quickly reduce the humidity inside the car. Of course, combining this with the air conditioning will yield faster results. Air Conditioning Heating: Use the method of reducing the temperature difference to remove fog. In winter, use warm air to blow hot air onto the glass, quickly raising the temperature of the front glass and reducing the temperature difference between the inside and outside surfaces of the window. This can prevent excessive fogging of the windshield in time. However, it should be noted that the rear and side windows heat up more slowly, so it takes longer to remove all the fog. Whether the air conditioning is automatic or manual, turning it on helps with dehumidification. The temperature control should not be set to the coldest position, as this can cause the outer surface of the windshield to fog up over time. Applying Anti-Fog Spray or Other Preventive Measures: Spray a small amount of defogging agent on the car windows and wipe it clean to remove dirt and stains. While polishing the glass, a thin transparent protective film is formed on the glass, effectively preventing water vapor from condensing and forming fog. This is especially useful in cold winters. Alternatives to anti-fog spray include dishwashing liquid, soapy water, glycerin, alcohol, or salt water. After drying, wipe off any excess residue with a chamois or soft dry cloth. This can keep the car windows fog-free for several days. Opening Windows for Airflow: If the fog inside the car is not too heavy, you can open the windows on both sides to allow air to flow between the inside and outside of the car, reducing the temperature difference and causing the fog to disappear slowly. The principle of this method is the same as using cold air from the air conditioning. The downside of opening windows for airflow is obvious: it cannot be used in rainy or snowy weather, on highways, or when the fog is heavy. Rear Window Heating: Most cars have a rear window heating function. The button position may vary, but the function is the same. Turn on the rear window heating switch, and the fog on the rear window will disappear in about a minute.

How Does the Tire Pressure Monitoring System Work in Cars?

Car tire pressure monitoring systems operate on different principles depending on the monitoring method: 1. Direct TPMS: Uses pressure sensors installed inside the tires to measure air pressure, then transmits this data wirelessly from the tire to a central receiver module; 2. Indirect TPMS: When tire pressure decreases, the vehicle's weight causes that wheel's rolling radius to shrink, allowing the system to monitor pressure by comparing rotational speed differences between tires. The functions of car tire pressure monitoring are: 1. Preventing accidents; 2. Extending tire service life; 3. Reducing wear on suspension systems.

Why is there fog in the car when it hasn't been driven?

Fog forms in a stationary car due to the temperature difference between the inside and outside of the vehicle. The amount of fog depends on the extent of this temperature difference. Hazards of fog in a car: 1. Interference with driving: Fog in the car can obscure the driver's vision, causing significant interference with driving. 2. Increased risk of accidents: In winter, cars are particularly prone to fogging. According to data from the National Ministry of Transport, winter accounts for 39.62% of annual traffic accidents, with poor visibility and bad road conditions contributing to half of these winter accidents. The fatality rate in winter traffic accidents is also notably higher.
