What Causes the Engine Warning Light to Turn On and Then Off?

The engine warning light turns on and then off due to excessive carbon buildup inside the throttle body. The responsiveness of the vehicle's acceleration is closely related to the cleanliness of the throttle body. Cleaning the throttle body can reduce fuel consumption and make the engine more agile and powerful. However, if there is excessive carbon buildup or excessive dirt and sludge in the throttle body, it can lead to poor engine acceleration, increased fuel consumption, and trigger the engine warning light. Relevant information about the throttle body is as follows: 1. The throttle body is a controllable valve that regulates the air entering the engine. There are two types: traditional cable-operated and electronic throttle bodies. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to perform work. 2. Throttle bodies come in two types: traditional cable-operated and electronic. In traditional engines, the throttle control mechanism operates via a cable (flexible steel wire) or linkage rod, connecting one end to the accelerator pedal and the other to the throttle linkage plate. Electronic throttle bodies primarily use a throttle position sensor to control the throttle opening angle based on the engine's energy requirements, thereby regulating the amount of air intake.

What is the fuel tank capacity of the Buick Excelle?

The 2021 Buick Excelle offers a total of 4 models, all with a fuel tank capacity of 44 liters. The 2021 Buick Excelle is equipped with either a 1.3-liter turbocharged engine or a 1.5-liter naturally aspirated engine, paired with an automatic transmission (AT), and all models feature front-wheel drive. In the same class, the 2022 Nissan Sylphy Classic 1.6XE manual comfort version has a fuel tank capacity of 50 liters, while the 2021 Ford Focus Sedan 1.5L manual version has a fuel tank capacity of 53 liters. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe limit. There is additional space from the safe limit to the tank opening, which is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the instrument panel, which is marked with E and F. When the needle is close to E, it indicates low fuel, and when it is near F, it means the fuel level is sufficient.

What are the reasons for low tire pressure in cars?

Tire pressure can be low for many reasons, mainly including damage to the car tires and slow air leakage due to aging of the car tires. Hazards of excessive tire pressure: Tire friction and adhesion will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear of the tread pattern in the center of the tire, shortening tire life; increased body vibration indirectly affects the lifespan of other components; it causes excessive stretching deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the car while driving; puncture resistance decreases. When encountering sharp objects such as nails or glass on the road, they can easily penetrate the tire, and the impact can cause internal cracks and explosions, leading to a blowout. Hazards of insufficient tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; it makes the steering wheel heavy and prone to deviation, among other factors detrimental to driving safety; it increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; it reduces the function of the cords and rubber, leading to delamination or cord breakage, and excessive friction between the tire and the rim can damage the bead area, causing abnormal wear; friction between the tire and the ground increases exponentially, rapidly raising the tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a blowout; it increases tire body deformation, making the tire side prone to cracks while generating flexing motion, leading to excessive heat, promoting rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear.

Is ETC free on highways?

ETC is free on highways during holidays, and offers certain discounts at other times. According to State Council regulations, starting from 2020, vehicles without ETC cannot enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual lanes. Additionally, newly installed ETC devices cannot be used on highways immediately; they need to be activated before normal use. Users can also enjoy a 5% discount on tolls (discounts may vary by bank). For vehicles already equipped with ETC, passing through ETC lanes will not incur charges. Notes: Entering and exiting through ETC lanes will not incur charges. Entering through an ETC lane and exiting through a manual lane allows normal passage without charges, but note that this does not form a complete transaction record, which may affect normal highway passage next time. Entering and exiting through manual lanes will not incur charges. If entering through a manual lane and attempting to exit through an ETC lane, the exit barrier will not lift due to the lack of entry information. In this case, you can choose to exit through a manual lane. ETC charging principle: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane, and using computer networking technology for backend settlement with banks, vehicles can pay tolls without stopping at toll stations. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Promotes low-carbon travel, as vehicles pass toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improved efficiency: Theoretically, ETC lanes can increase vehicle throughput by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, key city clusters will basically achieve interoperability of transportation smart cards, and the proportion of vehicles equipped with ETC will significantly increase." It also set a clear target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and increasing the ETC adoption rate for passenger vehicles, efforts will also be made to promote ETC usage for trucks in the future.

What type of engine oil is suitable for Vios?

Vios can use engine oil with a viscosity of 5W-30. Mainstream engine oil brands include: Mobil, Castrol, Shell, and Dusso Lubricants. Engine oil plays multiple roles such as lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the "blood" of a car. Below are some related details: 1. Engine oil consists of base oil and additives. Base oil is the main component of lubricants, determining their fundamental properties, while additives compensate for and improve any shortcomings in the base oil's performance, providing certain new characteristics. Additives are an essential part of lubricants. 2. The SAE viscosity classification for winter oils includes grades: 0W, 5W, 10W, 15W, 20W, 25W. The symbol 'W' stands for winter, and the smaller the number before 'W', the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. 3. The SAE viscosity classification for summer oils includes grades: 20, 30, 40, 50. The larger the number, the higher the viscosity and the higher the applicable maximum temperature. 4. The SAE viscosity classification for all-season oils includes grades: 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, 10W-30, 10W-40, 10W-50, 15W-20, 15W-30, 15W-40, 15W-50, 20W-20, 20W-30, 20W-40, 20W-50. The smaller the number representing the winter part (indicating a lower applicable minimum temperature), and the larger the number representing the summer part (indicating a higher applicable maximum temperature), the wider the applicable temperature range.

What Causes the ABS Light to Illuminate in a Buick Excelle?

ABS light illumination can occur in various states, with different causes and solutions for each state, as detailed below: State 1: ABS warning light remains constantly illuminated (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting its ability to detect the corresponding wheel speed signal. This prevents the ABS control unit from determining the vehicle speed or wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the contaminants from the wheel speed sensor and adjust the gap between the sensor and the tone ring to restore normal function. Cause 2: Poor signal transmission due to loose system wiring connections or faulty ABS relay contacts. Solution: Inspect wiring connections and reconnect any loose terminals. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple electrical components are in use, battery voltage drops below 10.5V. As engine speed increases, voltage rises, causing the ABS light to turn off. This may also indicate insufficient power supply voltage to the ABS system due to poor terminal contact or grounding issues. Solution: Check battery specific gravity; inspect the charging system; verify power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light remains illuminated after engine start until the engine is turned off (IGFF). Cause: Poor grounding connection of the ABS hydraulic valve body; faulty wiring harness connector at the ABS hydraulic valve body; ABS control unit malfunction. Solution: Loosen and retighten the hydraulic valve body ground screw, cleaning the contact surface if necessary; check for enlarged connector gaps; replace the ABS or ABS/ASR control unit. State 4: ABS warning light illuminates during high-speed driving. Cause: The ABS control unit detects a significant discrepancy between rear and front wheel speed signals during high-speed driving; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's specified tire and wheel rim dimensions, typically listed on the fuel filler cap label. State 5: ABS warning light intermittently illuminates. Cause: Improper brake light switch adjustment; internal contact failure in the brake light. Solution: With the engine running, fully depress the brake pedal and manually push the brake switch linkage downward to complete self-positioning; replace the brake light switch if necessary. When the ABS warning light is illuminated, it is recommended to avoid continued driving. An illuminated ABS light indicates a malfunction in the anti-lock braking system. During emergency braking, wheel lock-up may occur, causing loss of vehicle control and skidding, which prevents the driver from decelerating or adjusting the vehicle's trajectory, posing significant safety risks.
