What Causes the Engine Warning Light to Illuminate in a Van?

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 or oil quality issues: Failure to use the fuel or oil specified 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 pumps, or clogged fuel lines can cause poor combustion. Turbocharging problems: Issues with the intake boost pipes or turbocharger can also trigger the engine warning light. The most common problem 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 the vehicle's intake system is compromised, it may lead to engine pipe blockages, and in severe cases, the engine warning light will illuminate. A dirty or uncleaned air filter can cause intake issues. Exhaust problems: Exhaust system faults can also cause the engine warning light to illuminate. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings. The catalytic converter is the most frequent culprit, often due to the use of leaded gasoline, lead or silicon-based oil additives, physical damage, or fuel system malfunctions. Anti-theft system malfunction: If the vehicle's electronic anti-theft system fails or the anti-theft controller does not match the engine ECU, the anti-theft system may prevent the engine from operating normally, accompanied by the illumination of the engine warning light. If the engine warning light illuminates, follow these steps: First, check if the engine is running normally. Look for symptoms such as shaking or black smoke. If present, avoid restarting the engine. Note: Never restart the engine if the light is red. If the engine can start, turn it off for 5-10 minutes. Then, without pressing the brake, press the start button or turn the key halfway to the "ON" position (without pressing the clutch). The vehicle will enter self-diagnosis mode. After 5-10 seconds, check if the warning light turns off. If the light remains on, visit a service center as soon as possible. Technicians can use a diagnostic tool to read the trouble codes and identify the issue for targeted repairs.

When will China V vehicles no longer be allowed to be registered?

China V emission vehicles cannot be registered in 2023. The country has divided the "China VI standard" into two phases: "China VI A" and "China VI B", which were implemented nationwide on July 1, 2020, and July 1, 2023, respectively. However, many regions have implemented the China VI emission standard ahead of schedule. In cities where the China VI standard has been implemented, registration of China V vehicles has already been stopped, while cities that have not implemented the China VI standard are not affected. Phase 6A: Implementation time for gas vehicles is July 1, 2019; for urban vehicles, it is July 1, 2020; and for all vehicles, it is July 1, 2021. Phase 6B: Implementation time for gas vehicles is January 1, 2021, and for all vehicles, it is July 1, 2023. Methods to check the emission standard: Check the motor vehicle certificate of conformity. When the car leaves the factory, it comes with a vehicle certificate of conformity, which clearly states the vehicle's emission standard. You can look for the vehicle list, where the vehicle information column contains the car's emission standard. Check the certificate of conformity, which includes exhaust emissions and indicates the corresponding emission standard. Log in to the Motor Vehicle Environmental Protection Website to inquire. Find the public inquiry platform at the bottom of the homepage, enter the corresponding vehicle VIN code, and input the last six digits of the engine number to check. Inspect the vehicle's environmental protection label. On the back of the environmental protection label on the car's front windshield, there is a clear mark indicating the vehicle's emission standard. The China V vehicle emission standard stipulates limits on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles. Nitrogen oxide emissions must be reduced by 25%. After the implementation of the China VI standard, vehicle exhaust emissions will be more than 50% lower than those under the China V emission standard. In terms of emission standards, nitrogen oxides are reduced by 77%, and particulate matter is reduced by 67%. Compared to China V models, China VI models are equipped with engines that use more efficient three-way catalytic converters. This not only improves the engine's power performance but also reduces the pollutants emitted by the vehicle, thereby helping to improve the environment.

What is the function of KDSS?

Automotive KDSS system functions to prevent further vehicle roll. Here are detailed explanations about the automotive KDSS: 1. Definition: The KDSS system utilizes a bidirectional hydraulic pipeline and interconnected front/rear hydraulic cylinders to form cross-linked front and rear stabilizers. When ordinary driving vehicles experience roll, the KDSS system effectively prevents fluid circulation within these stabilizers. 2. Precautions: The automotive KDSS system can adjust according to different road conditions. In off-road mode, since the stabilizer bars don't twist, the suspension travel increases compared to conventional suspensions, allowing the KDSS system to adapt to varying terrain.

What to Do When There's Metal Friction Noise During Low-Speed Driving?

First, identify the source of the abnormal noise. If you're unsure where the noise is coming from, start by checking these areas yourself: 1. Specific causes: For door noises, since the door structure is relatively simple, first check if screws are loose. For dashboard noises, these are generally related to the overall build quality and materials of the vehicle. Consider whether the dashboard panel has been previously removed, if navigation wiring was installed, if everything was reassembled correctly, or if any parts were improperly fitted. 2. Solutions: If the noise comes from the chassis or outside the vehicle, it's generally recommended to visit a 4S shop for diagnosis.
