The reasons for the engine oil warning light to illuminate include the following: 1. Insufficient engine oil level. Normally, driving causes oil consumption, and the oil pump's output decreases due to the low oil level, eventually leading to a drop in oil pressure and triggering the warning light. 2. Overheating engine. Prolonged aggressive driving keeps the engine under high temperature and heavy load conditions. Even if the oil level is sufficient, excessive heat thins the oil, causing it to leak through gaps and resulting in reduced oil pressure. 3. Damaged oil pump. Wear and tear or excessive assembly gaps in the oil pump components can prevent the pump from delivering sufficient oil during operation, causing the warning light to activate. 4. Incorrect oil selection. Choosing lower-grade or viscosity-incompatible oil to save costs can lead to oil leaks, resulting in insufficient oil pressure and triggering the warning light.

Do You Need to Wait for a Red Light When Making a Random U-Turn?

If there is a U-turn signal light and it is red, you must wait; otherwise, it will be considered running a red light. According to the "Road Traffic Safety Law," this will result in: 6 penalty points and a fine of 200 yuan. If there is no U-turn signal light, and the gap is marked with a dashed line, the U-turn is not affected by the traffic light and does not require crossing the pedestrian crossing. If the gap is marked with a solid line, 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 on the left side of the road must slow down and proceed safely to allow pedestrians to cross. Pedestrians waiting outside the boundary line between motorized and non-motorized lanes. If they have not entered the road, vehicles should slow down and proceed safely to allow them to cross. If pedestrians cross the boundary line between lanes, vehicles failing to stop and yield is a violation and should be penalized. When pedestrians enter the motorized lane via the crosswalk, vehicles must slow down and proceed safely. Failure to stop and yield is a violation and should be penalized. Pedestrians waiting at the centerline of the road without entering the vehicle lane. Vehicles failing to stop and yield is a violation and should be penalized. Pedestrians crossing the centerline of the road into the lane. Vehicles failing to stop and yield is a violation and should be penalized. If the road is divided by a green belt, pedestrians waiting in the middle area must be allowed to cross safely by slowing down. Cases where U-turns are allowed: Intersections with U-turn signs: If there is a clear U-turn sign at the intersection, a U-turn is permitted. If there is a U-turn signal light, follow its instructions. If there is no signal light, make the U-turn without obstructing other vehicles or pedestrians. Intersections without explicit "No U-turn" or "No Left Turn" signs: If there are no explicit prohibitions, a U-turn is allowed. This means if there are no "No U-turn" or "No Left Turn" signs and the centerline is not solid, a U-turn is permitted. Yellow grid lines also allow U-turns: Yellow grid lines are no-parking zones, typically marked at intersections prone to congestion. While stopping on yellow grid lines is prohibited, making a U-turn is allowed if there are no central barriers. Intersections with U-turn signal lights: If there is a U-turn signal light, follow it—only turn on green. When "No Left Turn" and "U-turn Allowed" signs appear together: U-turns are permitted, but left turns are prohibited. Note that "No U-turn" is not the same as "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, even without a "No U-turn" sign, U-turns are not allowed 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, U-turns are not permitted at that intersection. Always yield to straight-moving vehicles before making a U-turn. Failure to do so may result in full liability for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow. If a straight arrow is present, U-turns are prohibited even without explicit "No U-turn" signs.

What does GPF mean?

Automotive GPF refers to the Gasoline Particulate Filter, with relevant information as follows: 1. GPF: It is a ceramic filter installed in the exhaust system of gasoline engines, capable of capturing particulate emissions before they enter the atmosphere. 2. Wall-Flow Particulate Filter: The filtration mechanism of GPF is basically the same as that of diesel engine's DPF. Exhaust gases flow at a certain velocity through porous walls, a process known as "Wall-Flow." The wall-flow particulate filter consists of honeycomb-shaped ceramics with a certain pore density. By alternately blocking the honeycomb-shaped porous ceramic filter body, the exhaust flow is forced to pass through the channel walls, and particulate matter is captured and filtered through four methods: diffusion, interception, gravity, and inertia.

What does APS malfunction mean?

There is no APS malfunction indicator on vehicles, only the ABS warning light indicates an Anti-lock Braking System fault. Below are specific details about the ABS system: 1. ABS system function: ABS is the vehicle's Anti-lock Braking System, which belongs to the active safety systems of automobiles. When the ABS light illuminates, it indicates that the vehicle's computer has detected a fault in the ABS system. 2. Reasons for ABS light activation: Under normal driving conditions, the ABS remains dormant. It only activates during emergency braking situations, such as high-speed hard stops, when the vehicle's computer determines ABS intervention is necessary. When the ABS light comes on, it's often due to malfunctioning wheel speed sensors. The ABS computer cannot detect the driving conditions of each wheel or compare the slip ratios between wheels, preventing the ABS system from functioning properly.
