If the CO (carbon monoxide) level is found to be non-compliant during the vehicle inspection, here are several solutions: 1. Replace the spark plugs. 2. Clean the contacts of the distributor and the distributor rotor. 3. Adjust the ignition timing. 4. Clean the air filter. 5. Use a cleaning agent to clean the throttle body. 6. Clean the three-way catalytic converter and the oxygen sensor. Additional Information: 1. Definition of Vehicle Inspection: The vehicle annual inspection process refers to the fixed procedure that motor vehicles must undergo each year for inspection. It is a mandatory test for every vehicle, equivalent to a physical examination for the vehicle, aimed at promptly eliminating potential safety hazards and reducing the occurrence of traffic accidents, commonly known as vehicle inspection. 2. Specific Process: The inspection includes checking the vehicle's appearance, exhaust emissions, brakes, lights, chassis, and the compulsory insurance documents, among other items.

What is the failure rate of the 2020 Roewe i5?

Roewe i5 (2-12 months) main failure types include engine accounting for 7%, interior 5%, body appearance 5%, functional operation 5%, and transmission system 5%. Oil pump failure: Dirty or viscous oil prevents the oil pump from effectively sucking in and pumping out oil, resulting in low or no oil pressure. The solution is to change the oil. Pressure relief valve too soft: The function of the valve disappears or weakens due to the pressure relief valve or relief valve spring being too soft, stuck, or the steel ball being damaged, leading to reduced oil pressure. The solution is to replace and repair. Low oil pressure: Oil pressure sensor, pressure gauge, or circuit failure causes low oil pressure. The solution is to replace and inspect.

What kind of paint is the white color on the 2021 CR-V?

2021 CR-V white is pearl paint. Standard paint: Standard paint is the most common type of car paint, representing the most basic and simplest process. Most single-color white, red, and yellow cars you see typically use standard paint. Its composition includes resin, pigment, and additives. In the car paint manufacturing process, standard paint is a single-stage process. Since it doesn't involve mixing with other materials, it has lower costs and simpler procedures. Maintenance and touch-ups are also less complicated. However, being purely single-color paint, its appearance tends to be somewhat monotonous compared to other types of paint that can achieve dazzling, crystal-like luster. Additionally, standard paint surfaces are generally softer than other types of paint, making them more prone to chipping when hit by stones. Metallic paint: Metallic paint, also known as metal flake paint, typically incorporates aluminum or copper powder into the paint base. When light hits these metal particles on the car surface, the light reflects through the clear coat, creating a sparkling metallic appearance. In the spraying process, metallic paint is a two-stage process, requiring a clear coat to be applied over the metallic base to achieve the desired gloss and hardness.

What is the fuel tank capacity of the 2020 Sagitar?

The fuel tank capacity of the 2020 Sagitar is 50 liters, and the recommended gasoline specification is 95 octane or higher unleaded gasoline. The Sagitar is a compact car under FAW-Volkswagen. The 2018 Sagitar had a fuel tank capacity of 55 liters, while the 2019 Sagitar has a fuel tank capacity of 50 liters, with the same gasoline specification of 95 octane or higher unleaded gasoline. If the owner wants to check the remaining fuel level, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it indicates that the fuel is running low, and when it is near F, it means the fuel level is sufficient. The maintenance of the fuel tank is as follows: Drain accumulated water and sediment from the fuel tank, and check for any oil leakage at the fuel pipe joints and switches. For fuel tank caps equipped with air valves and vapor valves, also check if the vent holes are clear. The filter screen at the fuel filler inlet should be kept intact to prevent impurities from entering the fuel tank during refueling, which could clog the fuel lines. The sealing gasket of the fuel filler cap should also be intact to prevent fuel from spilling out during driving.

What is the reason for the jerking of the Malibu XL 9AT transmission?

The reason for the jerking of the Malibu XL 9AT transmission is a damaged solenoid valve. Here are the detailed reasons: Computer system failure: If the jerking sensation in the transmission is not due to a problem with the cooling system, it is likely caused by a failure in the transmission computer system. This issue is most common in automatic transmission vehicles. In such cases, reprogramming is required, and it is best to visit a professional auto repair shop for this service. Dirty cooling system: If you notice a jerking sensation in your car's transmission, first check if the transmission temperature exceeds the normal range. If it is indeed abnormal, then the transmission cooling system needs to be inspected. Generally, the issue lies with the cooling system. At this point, check for any blockages and clean them if present.

What is the wading depth of the Malibu XL?

The wading depth of the Malibu XL is approximately 25 centimeters. As long as the water does not exceed half of the tire height, it is generally safe. Introduction to wading depth: For vehicles, the wading depth mainly depends on the height of the car's chassis, which is the ground clearance listed in the specifications when purchasing the car. This also indicates that the higher the car's chassis, the greater its wading capability. Off-road vehicles typically have strong wading abilities, while urban SUVs may require more consideration in this regard. SUV models generally have higher chassis clearance compared to regular sedans. How to determine the wading depth: For regular sedans, the optimal wading depth reference value is the radius of the car's tires. At this level, it is relatively safe for the vehicle, ensuring that the engine does not take in water and that water does not seep into the car through the chassis. Judging the wading depth based on the wheels is an intuitive and effective method.
