What Are the Must-Know Driving Tips for Beginners?

How to Adjust the Throttle Position Sensor?

Here are the steps to adjust the throttle position sensor: 1. Loosen the two fixing screws of the throttle position sensor. 2. Insert a 0.35mm feeler gauge between the throttle stop screw and the stop lever, while using a multimeter to measure the quick switch conduction status. 3. Rotate the throttle position sensor counterclockwise to disconnect the quick switch contacts, then slowly rotate it clockwise. 4. Tighten the two fixing screws. Below are the functions of the throttle position sensor: 1. Detects whether the engine is in idle condition or under load, and whether it is accelerating or decelerating. 2. The throttle position sensor, also known as the throttle opening sensor or throttle switch, is a device used to detect the engine's operating state. 3. The working principle of the throttle position sensor is: converting changes in throttle opening into electrical signals input to the electronic control unit (ECU), which then determines the engine's operating condition based on the throttle position signal.

What to Do If the ETC Device Falls Off?

ETC needs to be reinstalled and reactivated after falling off. The installation process for the ETC device is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU; the red light will briefly turn on, and the OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning properly. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then, peel off the adhesive backing of the OBU and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device. Method to activate the ETC device: Insert and remove the ETC card twice in succession until the electronic tag screen displays "Bluetooth On." If "Tag Invalid" appears when inserting and removing the card twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth and open the corresponding mobile app (usually with a download QR code on the electronic tag). Navigate to the device activation interface. Click "Connect Device" and wait patiently for the "Connection Successful" prompt. Once connected, upload a photo of the vehicle's front to complete activation.

How to Read Tire Size Codes?

Tire size codes are printed on the sidewall of the tire. Upon close inspection, you can find numerical sequences similar to the following example. For instance, P215/65R15-89H: 1. "P" stands for Passenger car tire (to distinguish from tires designed for trucks or other vehicle types); "215" indicates the section width of the tire, which is the distance between the two sidewalls (measured in millimeters). This width varies depending on the rim width the tire is matched with: wider rims pair with wider tires, and narrower rims with narrower tires. Generally, the width marked on the sidewall refers to the width when the tire is mounted on a rim of the recommended width. 2. "65" is the aspect ratio, representing the ratio of the tire's height to its width. Here, it means the height is 65% of the width. The smaller the number, the flatter the tire appears; "R" denotes the tire's construction, indicating it's a Radial tire, meaning its cord plies are arranged radially within the tire body. "B" signifies a Bias-ply construction, though bias-ply passenger car tires are no longer in production. 3. "15" indicates the rim diameter (in inches). This tire must be paired with a 15-inch rim; otherwise, it cannot be installed. "89" represents the load index, with this tire's maximum load capacity being 1,279 pounds. Different load indices correspond to different maximum load capacities (usually measured in pounds or kilograms). 4. "H" indicates the speed rating, meaning this tire's maximum speed is 130 miles per hour. In the older European sidewall marking system, it would be denoted as 215/65HR15. Different letters represent different speed ratings.

How to Distinguish Between China 5 and China 6 Emission Standards for Vehicles?

China 6 and China 5 mainly differ in the content of emissions. When purchasing a new car, you can check the vehicle's factory certificate and the environmental standard list to distinguish between them. Below is some information about China 6 and China 5: 1. The primary difference between China 6 and China 5 lies in the emission content, with China 6 standards being significantly lower than China 5 standards. 2. The carbon monoxide emission limit for gasoline vehicles under China 5 standards is 1000 mg/km, while under China 6 standards, it is 700 mg/km. 3. The emission limits of 'China 6 standards' are approximately 40% to 50% stricter than those of 'China 5 standards'.

What Type of Driver's License is Required for Agricultural Vehicles?

Agricultural vehicles generally require a C3 driver's license. Here is some information about the C3 driver's license: 1. The C3 driver's license is issued by the vehicle management office as a certification for operating low-speed trucks. With a C3 license, you can drive agricultural transport vehicles or light-duty trucks with a length of less than 6 meters and a total weight of less than 4500KG. Additionally, a C3 license also permits the operation of three-wheeled vehicles covered under the C4 license. 2. Low-speed refers to a maximum speed not exceeding 70km/h. These vehicles are generally not allowed on urban main roads and are commonly seen in rural or suburban areas.

How to Solve the Problem of Unstable Car Idling Speed Fluctuating Up and Down?

Solutions to unstable car idling speed fluctuating up and down: adjust the throttle valve and idle speed to ensure the engine operates at the lowest stable speed. The throttle valve is a controllable valve that regulates air intake into the engine, available in two types: traditional cable-operated and electronic throttle. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture for combustion and power generation. It connects to the air filter at the top and the engine block at the bottom. The responsiveness of the car's acceleration is closely related to the cleanliness of the throttle valve. Car idling refers to an operating condition where the engine runs without load, meaning the car is in neutral gear. The engine speed during idling is called the idle speed, which can be adjusted by altering the throttle opening size. Idling essentially means the engine is running but not performing work.
