What Does It Mean When the Engine Warning Light on the Dashboard Comes On?

The engine warning light may come on due to the following 7 main reasons: Sensor malfunction: The sensors involved include those for coolant temperature, crankshaft position, air flow, intake temperature, oxygen, etc. When these sensors are damaged, have poor contact, or their signals are interrupted, the vehicle's ECU cannot accurately obtain engine data, which triggers the engine warning light. Fuel or oil quality issues: Failure to use the fuel or engine oil as recommended by the manufacturer may cause engine wear, leading to the warning light illuminating. Poor fuel mixture combustion: Poor combustion can cause engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will turn on as an alert. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can all lead to poor fuel mixture combustion. Turbocharger problems: Issues with the intake boost pipes or turbocharger can also trigger the engine warning light. The most common problem is a damaged turbocharger, often 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, the engine warning light will come on. A dirty air filter that hasn't been cleaned regularly can cause intake problems. Exhaust problems: Exhaust system faults can also trigger the engine warning 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-containing lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can all 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 control unit, 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 comes on, follow these steps: First, check if the engine is running normally. Look for symptoms like shaking or black smoke. If present, avoid restarting the engine. Note: Never restart the engine if the light is red. If the engine can be started, turn it off and wait 5-10 minutes. Without pressing the brake, press the start button or turn the key halfway to the 'ON' position (without pressing the clutch). The vehicle will perform a self-check. After 5-10 seconds, observe 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 fault code, identify the issue, and perform targeted repairs.

Do I need to wait for the red light to make a U-turn at a designated area?

If there is no U-turn indicator light, and the gap is marked with a dashed line, the U-turn is not affected by the left-turn signal light and does not require crossing the pedestrian crossing. If the gap is marked with a solid line, then the U-turn must cross the pedestrian crossing and is subject to the left-turn signal light. Making a direct U-turn may result in being photographed or penalized by on-site traffic police. If you need to cross the pedestrian crossing to make a U-turn, you must yield to pedestrians: Pedestrians walking on the right side of the road's crosswalk, not reaching the centerline of the road. Vehicles driving on the left side of the road should slow down and ensure safety before proceeding through the crosswalk. Pedestrians waiting outside the boundary line between motorized and non-motorized lanes. If they have not entered the roadway, vehicles should slow down and ensure safety before proceeding through the crosswalk. When pedestrians cross the boundary line between motorized and non-motorized lanes, vehicles that do not stop and yield are committing a violation and should be penalized. When pedestrians enter the motorized lane along the crosswalk, the motorized vehicle should slow down and ensure safety before proceeding through the crosswalk. If the vehicle does not stop and yield, it is committing a violation and should be penalized. Pedestrians waiting at the centerline of the road without entering the motorized lane. If vehicles do not stop and yield, it is a violation and should be penalized. Pedestrians crossing the centerline of the road and entering the lane. If vehicles do not stop and yield, it is a violation and should be penalized. When the road is divided by a green belt, pedestrians waiting in the middle of the road must be yielded to. Vehicles should slow down and ensure safety before proceeding through the crosswalk. Scenarios where U-turns are allowed: If there is a U-turn sign at the intersection, you can make a U-turn. If there is a U-turn signal light, follow its instructions. If there is no signal light, make the U-turn based on the specific situation without obstructing other vehicles or pedestrians. If there is no explicit prohibition of U-turns or left turns at the intersection, U-turns are allowed. "No explicit prohibition" means there are no "No U-turn" or "No Left Turn" signs, and the centerline is not solid. U-turns are also allowed in yellow grid zones. Yellow grid lines indicate no-parking zones at intersections prone to congestion due to temporary stops. While vehicles cannot stop in these zones, they can make U-turns if there is no central barrier. If there is a U-turn signal light at the intersection, follow it—only proceed on green. If "No Left Turn" and "U-turn Allowed" signs appear together, U-turns are allowed, but left turns are prohibited. Note that "No U-turn" does not mean "No Left Turn." Precautions when making a U-turn at an intersection: Observe road markings. If the line is solid, U-turns are prohibited under any circumstances. Continue driving to find a suitable U-turn location. If there is a "No Left Turn" sign ahead, even if there is no explicit "No U-turn" sign, U-turns are not allowed at that intersection because U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, you cannot make a U-turn at that intersection. Always yield to vehicles going straight before making a U-turn. If you interfere with straight-moving traffic, you will bear full responsibility for any accidents. Near the intersection stop line, lanes usually have guiding arrows. The leftmost lane is not always a left-turn lane. If it has a straight arrow, U-turns are prohibited even if there are no explicit "No U-turn" signs.

How to Deal with Long Scratches on Car Paint?

Methods for dealing with long scratches on car paint: 1. Hairline scratches, which can usually be removed by polishing or gently wiping with a polishing compound; 2. Light scratches, for which you only need a tube of toothpaste. Toothpaste is very effective for shallow scratches that have not damaged the car's primer; 3. Moderate to deep scratches, which cannot be repaired by polishing. If the dent area is small and does not exceed 5mm, it can be leveled with filler putty before repainting; 4. Deep scratches, for which severe deformation requires bodywork. The treatment of scratches places relatively high demands on the technician's skills.

What are the factors affecting braking distance?

Factors affecting braking distance include driving speed, road conditions, driver condition, tire condition, and vehicle condition. Below is an introduction to automotive brakes: 1. Introduction: Automotive brakes are the braking devices of a vehicle, and almost all brakes used in vehicles are friction-based. 2. Categories: They can be divided into two main types: drum brakes and disc brakes. In drum brakes, the rotating element of the friction pair is the brake drum, with its working surface being cylindrical; in disc brakes, the rotating element is the rotating brake disc, with its working surface being the end face. 3. Function: Automotive brakes are components that generate forces (braking forces) to resist vehicle movement or the tendency of movement, including retarders in auxiliary braking systems.
