Built-in or External Tire Pressure Monitoring: Which is Better?

Both built-in and external types belong to the category of direct tire pressure monitoring systems, with both capable of meeting usage requirements in terms of functionality and quality, and there is no inherent superiority between the two. Below are the pros and cons of each type of tire pressure monitor: 1. Built-in tire pressure monitor: (1) Advantages ① More accurate monitoring data and stable performance. ② Installed inside the tire, making it theft-proof. ③ No need to remove during inflation. (2) Disadvantages ① Requires professional installation at an auto repair shop, which is a complex process. ② Unit price is higher than external types. 2. External tire pressure monitor: (1) Advantages ① Simple installation, allowing car owners to install it themselves by following the instructions. ② Unit price is lower than built-in types. (2) Disadvantages ① Monitoring accuracy is lower compared to built-in types. ② The sensor must be removed each time the tire is inflated. ③ Being exposed, it has poorer anti-theft performance. ④ If the air valve has defects or wear, installation may cause air leakage.

Do You Need to Turn on AC When Using the Heater?

You do not need to turn on the AC button when using the heater. The AC button is the switch for the car's air conditioning compressor, which is used for cooling. The car heater utilizes the internal heat circulation of the vehicle and does not require the air conditioning compressor to work. Therefore, to use the heater, you only need to adjust the fan speed and set it to the heating position without turning on the AC switch. Steps to turn on the car heater: 1. After starting the car, wait for about 8-15 minutes until the water temperature reaches the normal operating temperature, then you can turn on the heater. 2. Adjust the air conditioning circulation mode to internal circulation. 3. Switch to the heating mode, which may be indicated by a red zone or a sun symbol depending on the vehicle.

What Does It Mean When the Engine Fault Light Comes On When Starting the Car?

When the engine fault light comes on while starting the car, it could be due to the following reasons: 1. Sensor issues: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors may be damaged, have poor contact, or experience signal interruption. In such cases, the car's ECU cannot accurately obtain engine data, leading to the illumination of the engine fault light. 2. Maintenance issues: Poor engine maintenance is the most common cause of the engine fault light. Failure to perform regular maintenance, combined with poor driving habits, increases the burden on the engine. 3. Fuel and oil quality issues: Manufacturers usually recommend specific grades of fuel and types of engine oil. Not adhering to these recommendations can cause engine wear over time, eventually triggering the fault light. 4. Poor combustion of the air-fuel mixture: Faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can lead to poor combustion, resulting in engine carbon buildup or knocking. These issues are detected by the engine's oxygen sensor and reported to the ECU, which then illuminates the fault light as a warning. 5. Air intake issues: Proper air intake is essential for engine combustion. A dirty or clogged air filter can restrict airflow, leading to potential blockages and, in severe cases, triggering the engine fault light.

Are There Risks in Using the OBD Interface?

OBD interface is an international standard automotive communication interface. Generally speaking, using the OBD interface will not cause harm to the vehicle. However, if the electrical power of the interface is too high, it may lead to short circuits, burning out the OBD interface or causing the battery to drain. Below is more information about OBD: 1. OBD stands for On-Board Diagnostics, which refers to the onboard automatic diagnostic system. It consists of a scanner, oscilloscope, and interface, automatically diagnosing vehicle conditions and sending fault codes to maintenance personnel, enabling them to quickly locate faults. OBD provides significant assistance in vehicle maintenance and repair. 2. If the car's OBD interface is occupied, it is generally only used as a power source and does not affect the vehicle itself. This is because external devices only read the data from the vehicle's computer via the OBD interface and write programs.

What are the hazards of not replacing the air conditioning filter?

The hazards of not replacing the air conditioning filter include the following: 1. During engine operation, impurities such as dust and metal shavings will continuously mix into the cylinders. 2. In hazy weather, there is more moisture and pollutant particles in the air. After being inhaled, they tend to accumulate and solidify, which can cause poor air exchange in the engine and, over time, increase fuel consumption. 3. When haze enters the air conditioning system, moisture and dust will remain on the filter, making it very easy for bacteria to breed. 4. After turning on the air conditioning, it will not only affect the air intake but also contaminate the fan and ducts, leading to a series of problems.

Is Transmission Oil the Same as Engine Oil?

Transmission oil and engine oil are not the same. The differences between them are as follows: 1. Different properties. (1) Engine oil is the lubricant for the engine. (2) Transmission oil is a lubricant used to keep the gear system clean. 2. Different functions. (1) Engine oil lubricates and reduces friction in the engine, assists in cooling, seals against leaks, prevents rust and corrosion, and acts as a shock absorber. It is known as the 'blood' of the car. (2) Transmission oil ensures the normal operation of the transmission and extends the service life of the transmission components. 3. Different characteristics. (1) The engine is the heart of the car, containing many metal surfaces that rub against each other. These components move at high speeds in harsh environments, with operating temperatures reaching 400°C to 600°C. (2) Transmission oil has anti-low-temperature properties and provides effective lubrication even at low temperatures, reducing oil loss under severe operating conditions.
