What are the reasons for the engine warning light staying on for a long time?

The engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, triggering the engine warning light. Fuel quality issues: If fuel and engine oil are not added according to the manufacturer's requirements, it may cause engine wear and trigger the warning light. Poor combustion of 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 warning light will illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, and fuel line blockage can all cause poor combustion of the air-fuel mixture. Turbocharging issues: The intake turbocharging pipeline and turbocharger can also trigger the engine warning light. The most common issue is turbocharger damage, accompanied by symptoms such as oil leakage, high oil consumption, reduced power, metal noises, and blue or black smoke from the exhaust pipe. Intake issues: If the vehicle's intake system has problems, it may lead to engine pipeline blockage, and in severe cases, trigger the engine warning light. A dirty air filter that is not cleaned regularly can cause intake problems. Exhaust issues: Exhaust system faults can also trigger the engine warning light. Common causes include rear oxygen sensor failure, catalytic converter failure, exhaust camshaft and bearing failure, 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 vehicle's electronic anti-theft system fails or the anti-theft controller does not match the engine electronic controller, the anti-theft system can prevent the engine from operating normally and trigger the warning light. If the engine warning light is on, follow these steps: First, check if the engine is running normally, whether there is shaking, smoke, etc. If so, avoid restarting the engine. Especially note that if the light is red, do not restart the engine under any circumstances. If the engine can be started, turn it off for 5-10 minutes, then without pressing the brake, press the start button once or turn the key halfway to the "on" position without depressing the clutch. The vehicle will perform a self-check after powering on. Wait 5-10 seconds to see if the warning light turns off. If the warning light remains on, visit a service station as soon as possible. The service station can use a portable diagnostic tool to read the fault code, identify the issue, and perform targeted repairs.

What is the ECON function in cars?

The ECON in cars refers to the economy mode, with its full English name being ECONOMY. During vehicle operation, it comprehensively evaluates and analyzes factors affecting fuel consumption, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the optimal fuel quantity to supply the engine, effectively reducing fuel consumption compared to normal driving modes. Simply put, it controls the engine's speed with appropriate gear shifts to minimize unnecessary fuel consumption. When the automatic transmission operates in economy mode, its shifting pattern ensures the engine frequently runs within the economical speed range during driving, thereby improving fuel efficiency. The name ECO is derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). ECO is commonly known as the economy mode (energy-saving mode). Some manufacturers also refer to it as "ECON," but both can be understood as abbreviations for economy. ECO modes are divided into active and non-active types: Active ECO mode has a dedicated button, allowing the driver to choose whether to enable it. When the ECO mode switch is pressed, the dashboard indicator light illuminates, and the vehicle automatically adjusts settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active ECO mode does not have a dedicated button. When the dashboard ECO indicator light turns on, it serves as a reminder function. The ECO system automatically evaluates driving behavior, and when the current driving operation achieves the optimal fuel supply, the dashboard simultaneously displays the ECO indicator light. Modern automatic transmissions are designed with different shifting logics in the electronic control unit to meet the driving requirements of different users and adapt to various road conditions. A mode selection switch is also provided on the control panel, allowing drivers to choose the transmission control mode. Common automatic transmission control modes include the following: Standard Driving Mode (NORMAL): This is the most commonly used mode in cars. In this mode, the vehicle's performance is balanced in all aspects, such as fuel efficiency, quietness, and power. It achieves the best balance between fuel economy, quietness, and power performance, making it suitable for urban driving. Power Mode (POWER): This control mode is designed to maximize the vehicle's power performance. Under this mode, the automatic transmission's shifting pattern ensures the engine frequently operates within the high-power range during driving, thereby enhancing the vehicle's power performance and climbing ability. Snow Mode (SNOW): Some automatic transmission models feature a "snowflake" button near the gear lever, which activates the snow mode. It uses automated programming to make the transmission start in second gear, ensuring smoother and gentler torque output and reducing the likelihood of tire slippage on icy or snowy roads. Sport Mode (SPORT): The electronic control unit increases the engine speed to maintain sufficient torque and enhance power performance, though this results in higher fuel consumption. It temporarily boosts engine power for rapid acceleration. In simple terms, it acts as an acceleration gear, climbing gear, or overtaking gear. Using sport mode causes a sudden increase in engine speed. Additionally, high engine speeds in sport mode can help remove carbon deposits from the engine. However, it should not be used continuously, as the transmission experiences increased load, higher temperatures, and accelerated wear in this mode. Individual Mode (INDIVIDUAL): This mode allows drivers to customize the feedback of various modules, typically including steering wheel weight, chassis stiffness, throttle response, transmission reaction, engine mode, steering system mode, and exhaust system mode.

How to Maintain an Automatic Transmission?

Automatic transmission maintenance methods are: 1. Follow the manufacturer's requirements for regular inspections and timely replacement of specified transmission fluid; 2. Only about 30% of the total fluid volume can be drained through the drain bolt, and transmission cleaners should not be used; 3. For a complete transmission fluid change, use a transmission cleaner in conjunction with a transmission fluid exchange machine. An automatic transmission is a gear-shifting device that automatically changes gears based on vehicle speed and engine RPM, as opposed to a manual transmission. Types of automatic transmissions include: MT automatic transmission, AMT automatic transmission, AT automatic transmission, CVT automatic transmission, and DSG automatic transmission.

What are the causes of abnormal noise in the transmission?

Introduction to the causes of transmission noise: 1. Wear and damage of bearings. When bearings wear out, their clearance increases and their fitting accuracy decreases; when bearings are damaged, abnormal noise will occur due to their inability to operate normally, and may even cause damage to the transmission components, leading to further faults. 2. Abnormal gear meshing clearance. This can be caused by wear of transmission components or the use of parts with low precision during replacement, resulting in excessive clearance; or by overly tight gear clearance during assembly. 3. Metal peeling on gear tooth surfaces, broken gear teeth, or misalignment during assembly. 4. Insufficient lubricant leading to poor lubrication. The corresponding lubricant should be replaced. 5. Water ingress into the transmission. If not repaired in time, it may cause noise problems over time.
