Can I drive on the day the temporary license plate expires?

You can drive on the day the temporary license plate expires, as long as it's before midnight. The paper motor vehicle license plate that permits temporary road use, also known as a temporary vehicle license plate, is issued by the vehicle management department of the public security bureau for newly purchased vehicles before formal registration. The validity period of a temporary license plate generally does not exceed thirty days. A license plate, commonly referred to as a vehicle plate, is a panel made of materials such as aluminum, sheet iron, plastic, or paper, displaying the vehicle's registration number, registration region, or other relevant information. It is mounted on the front and rear of the vehicle. License plates serve to number and register vehicle information, primarily enabling identification of the vehicle's region of registration and facilitating access to the owner's details and the vehicle's registration information through the plate number.

How to Test a 2-Wire Crankshaft Position Sensor Circuit?

Measurement method for a 2-wire crankshaft position sensor circuit: Use the two probes of a multimeter to connect to the two signal wires of the magnetic crankshaft position sensor in any order (since it's AC, polarity doesn't matter). With the engine idling, set the multimeter to the AC 20V range. Generally, the higher the RPM, the higher the voltage. The crankshaft position sensor is usually installed inside the distributor and is one of the most important sensors in the control system. Its functions include: detecting engine speed (hence also called the speed sensor), detecting piston top dead center position (thus also known as the top dead center sensor), including detecting top dead center signals for each cylinder's ignition control and the first cylinder's top dead center signal for sequential fuel injection control.

What to Do When a Car Stalls in Water

Steps to handle a car stalling in water: 1. Immediately exit the vehicle to assess the flooding level and turn off the engine; 2. If the water level exceeds half of the tire, do not attempt to restart the car. Remove the key and roll up the windows to prevent water from entering the cabin; 3. Loosen the battery terminal screws and disconnect the negative battery cable to avoid short circuits caused by water damage to electrical components; 4. Remove the spark plugs and attempt to start the engine to expel water from the cylinders and exhaust pipe. After drying the spark plugs, reinstall them and try starting the car again. If the issue persists, call for roadside assistance immediately or seek help to move the vehicle out of the water to prevent prolonged submersion, which could damage the chassis. Always seek professional help promptly after a water-related incident to minimize further damage.

What needs to be replaced during the second maintenance of a car?

The second maintenance of a car requires an oil change and oil filter replacement. Some models may also require the replacement of air and cabin filters. The second maintenance also includes inspections and maintenance of dozens of items across multiple systems, such as the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires. Additionally, a full vehicle routine inspection is conducted, covering tires, brakes, chassis, suspension, lights, and various fluid levels. The second maintenance is typically performed when the new car reaches 10,000 kilometers. After the inspection and maintenance during the second maintenance, the overall condition of the car significantly improves, ensuring driving safety. Following the second maintenance, the new car's functions stabilize, and thereafter, minor maintenance should be done every 5,000 to 7,500 kilometers based on the car's condition and usage habits, while a comprehensive check-up and maintenance should be performed every 10,000 to 15,000 kilometers.
