Oxygen sensor failure reasons are: 1. The quality of fuel added to the car is too poor, which cannot be effectively burned in the engine cylinder, resulting in more harmful substances and impurities in the exhaust gas, leading to damage of the car's oxygen sensor. 2. When the spark plug fails and cannot ignite normally, the fuel and mixed gas in the engine cylinder cannot be effectively burned, which will damage the oxygen sensor. The oxygen sensor is a key feedback sensor in the electronic fuel injection engine control system, and it is a critical component for controlling vehicle exhaust emissions, reducing environmental pollution caused by vehicles, and improving the fuel combustion quality of the car engine.

Can the PCX use 10w40 engine oil?

Yes, but it will result in higher fuel consumption. It's better to use 5w30 engine oil. Below is relevant information about engine oil: Cleaning function: The cleaning function refers to removing carbon deposits, oil stains and other residues produced by combustion, either by dissolving them in the oil or removing them through the oil filter. Engine oil can clean the engine and remove impurities retained in the filter, protecting metal surfaces from corrosion caused by acids formed during combustion. Cooling function: As the name suggests, this refers to cooling the engine. Engine oil assists the cooling system (such as water, radiator, water pump, cooling circulation system, and airflow passing through the engine and oil sump) in dissipating heat generated by the pistons.

What does it mean when the sport light on the car is on?

When the sport light on the car is on, it indicates the sport mode, which is used to increase power output and deliver higher torque. Pressing this button will display a green rectangle with a sport logo on the dashboard. More information about the sport mode is as follows: Function: During the process of driving, switching to sport mode will delay the gear shift timing of the transmission, allowing the engine to maintain high RPM for a longer period. The transmission gear will drop, and the engine RPM will instantly increase, thereby enhancing the car's power output. Usage: Sport mode is not used during normal driving. It is only used when climbing slopes or overtaking. During the driving process, do not use sport mode continuously just to increase the car's power. Prolonged use of sport mode will increase the load on the transmission, raise its temperature, accelerate wear on internal components, and may also lead to higher fuel consumption.

What are the reasons why the Venucia D50 won't start?

For the BAIC Senova Venucia D50 that won't start, you can check for reasons such as circuit faults, excessive carbon deposits, fuel pressure issues, etc. Circuit faults or contact issues: ECU CAN bus failure, poor contact at the ECU CAN interface. Excessive dirt or carbon deposits: Too much dirt and carbon deposits can cause abnormal air flow, making it impossible to accurately control the normal intake air volume, resulting in unstable gas content and preventing the engine from working properly. Low fuel pressure and poor performance: Low fuel pressure combined with poor constant pressure performance leads to a low level of system atomization, making the car difficult to start.

What Causes a Gasoline Smell Inside the Car?

The reasons for a gasoline smell inside the car are as follows: 1. Leakage at the gasoline pipe connection: A leak at the gasoline pipe connection allows gasoline fumes to enter the car through the air conditioning system. Open the engine compartment cover to check for leaks, and if found, tighten the connection promptly or visit a repair shop for maintenance. 2. Aging rubber hoses: Rubber hoses in the engine compartment can deteriorate over time, especially in older vehicles, potentially causing gasoline to leak into the engine compartment. The air conditioning system can then draw these fumes into the car. 3. Issues with the gasoline vapor canister: Problems with the gasoline vapor canister, often due to overfilling the fuel tank for extended periods, can lead to saturation of the activated charcoal inside the canister, preventing it from effectively restoring its activity.
