I've been driving a Sylphy for several years, and the strange noise during acceleration is really annoying. The most common cause could be a loose or aging drive belt, which makes a squealing sound during acceleration, especially noticeable during cold starts. It could also be worn bearings, causing a humming noise when the wheels rotate. Damaged engine mounts can also produce vibration noises during acceleration. Once, I found that the noise was caused by a leak in the intake pipe—a quick trip to the repair shop and replacing a small part fixed it. The Sylphy uses a CVT transmission, so if the chain friction noise gets louder during acceleration, it's best to get it checked immediately. Regular maintenance is crucial; clean the engine bay every six months to prevent dust buildup from causing issues. Safety first—don't ignore a small noise, as delaying repairs could lead to costly damage.

Where does the eecu fault belong?

eecu belongs to internal faults. The following are the causes and solutions for eecu faults: 1. It may be a problem with the CAN line, or the CAN line plug may be loose or have poor contact. 2. Through troubleshooting, it was found that the shutdown switch wiring harness connector was flooded (close to the front wheel), and the pins were corroded. 3. After rust removal and anti-rust treatment of the pins, reconnection resolved the fault. 4. When communication between the engine ECM and the instrument is interrupted, the instrument will report this fault. The eecu is a very crucial computer in the car, which regulates the engine's operation. The eecu relies on many sensors to collect information and then uses actuators to regulate the engine's operation.

What is the fuel consumption of the Sylphy when the air conditioning is on?

8 liters per 100 kilometers. The following are relevant introductions: 1. Factors affecting fuel consumption: In addition to the vehicle's own design, actual fuel consumption is also related to road conditions, driving habits, load conditions, and vehicle condition. Different driving roads result in different engine power losses, naturally leading to variations in fuel consumption. In winter, lower temperatures lead to longer warm-up times, poorer fuel atomization, and lower combustion efficiency. In summer, using air conditioning increases engine resistance, so fuel consumption in winter and summer is indeed slightly higher than in spring and autumn. 2. Fuel-saving driving methods include: Avoid prolonged idling, do not open windows at high speeds, maintain normal tire pressure, avoid frequent lane changes, and refrain from sudden acceleration or hard pressing of the accelerator.

What is the difference between paying in full and financing when buying a car?

Those with sufficient funds can pay in full when buying a car, while financing benefits both the car owner and the 4S dealership. For the owner, it reduces the financial burden by not requiring a large one-time payment. For the dealership, it increases sales efficiency and may even generate additional fees during the financing process. The specific differences are as follows: 1. Financing a car purchase: Requires paying additional fees and interest on top of the car price, but the advantage is that the owner can drive the car home after paying a portion of the cost. 2. Paying in full: The benefit is that the car can be paid for outright without future concerns, but it requires a large one-time cash payment.
