What Are the Reasons for the Surge in New Energy?

What are the reasons for the engine warning light in Changan vehicles?

The engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: This includes sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor connections, or experience signal interruptions, the vehicle's ECU cannot accurately obtain engine data, triggering the engine warning light. Fuel and oil quality issues: Failure to use the fuel and oil as recommended by the manufacturer may cause engine wear, leading to the illumination of the warning light. Poor combustion of the air-fuel mixture: Poor combustion can result in engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pump failures, or clogged fuel lines can cause poor combustion. Turbocharging problems: Issues with the intake boost piping or turbocharger can also trigger the engine warning light. The most common issue is a damaged turbocharger, accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake problems: If there are issues with the vehicle's air intake, it may lead to clogged engine pipes, and in severe cases, trigger the engine warning light. A dirty or uncleaned air filter can cause intake problems. Exhaust problems: Exhaust system faults can also cause the engine warning light to illuminate. Common causes include faulty rear oxygen sensors, catalytic converter issues, or problems with the exhaust camshaft and bearings. The catalytic converter is the most frequent culprit. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily lead to catalytic converter failure. Anti-theft system malfunction: If the vehicle's electronic anti-theft system malfunctions or if there is a mismatch between the anti-theft controller and the engine ECU, the anti-theft system may prevent the engine from operating normally, and the engine warning light will illuminate. If the engine warning light is on, follow these steps: First, check if the engine is running normally, and look for symptoms like shaking or black smoke. If present, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'ON' position (without pressing the clutch). The vehicle will perform a self-check upon powering up. After 5-10 seconds, observe if the warning light turns off. If the warning light remains on, visit a service center as soon as possible. Technicians can use a portable diagnostic tool to read the fault codes, identify the issue, and perform targeted repairs.

How to Identify Stock Vehicles?

Methods to identify stock vehicles include: checking the vehicle production nameplate, examining the window production date, inspecting the vehicle identification number (VIN), and checking the car chassis. In the industry, stock vehicles generally refer to those that remain unsold for more than three months after being manufactured and leaving the factory. There are no national regulations specifying how many months define a stock vehicle. Potential issues with stock vehicles: 1. Various fluids, electronic components, batteries, rubber seals, and tires may suffer from moisture damage and aging due to prolonged storage without periodic inspection and maintenance; 2. Periodic inspection and maintenance measures are often minimal; 3. For vehicles stored too long without proper warehouse management, the aging of electronic components and rubber products may go unchecked, leading to issues like oil or power shortages.
