How to Deal with the Engine Red Warning Light?

Should You Warm Up the Car Before an Oil Change?

It is necessary to warm up the car before an oil change, typically for about 5 minutes. Below are the benefits of warming up the car before an oil change: 1. Engine oil is a liquid with a certain viscosity. If the temperature is low, the viscosity will be higher, making it difficult for the oil to flow out when the oil pan drain plug is removed. 2. There is some sludge inside the engine, which will soften after warming up the car, allowing it to be flushed out along with the old oil. 3. Removing the oil filter becomes easier after warming up the car. During an oil change, the oil filter should be replaced as well. There is a lot of oil and sludge around the oil filter, making it difficult to remove when the engine is cold. Additional note: When changing the oil, make sure to completely drain the old oil before adding new oil. Otherwise, the old oil can contaminate the new oil, reducing its lubrication effectiveness and performance.

What are the symptoms of a faulty electronic throttle body?

Electronic throttle body failure may cause the engine warning light to illuminate, engine idle shaking and unstable idle, stalling at low speeds, and other phenomena. Here is relevant information: 1. Use a computer diagnostic tool to check the engine module. If there are no permanent fault codes, replacement is generally not required. Read the throttle body's data stream to check the two position sensors and throttle opening. If the opening is large, first clean the carbon deposits on the throttle body, then perform throttle initialization. 2. If the throttle position sensor and motor have poor line contact, open circuit, or short circuit, check the throttle wiring harness connector for rust, water ingress, or widened connector tabs in case of poor contact. For open or short circuits, inspect the related throttle wiring by measuring voltage and circuit continuity.

Is there a fine for not wearing seat belts in the back seat on the highway?

If passengers are found not wearing seat belts on the highway, whether in the front or back seats, a fine of 50 yuan will be imposed according to the "Road Traffic Safety Law of the People's Republic of China"; for drivers who do not use seat belts as required while driving on the highway, a fine of 200 yuan and 2 demerit points will be imposed.

Which Subject to Retake After Losing All 12 Points?

After losing all 12 points, you need to retake Subject 1. If a driver accumulates 12 penalty points during the probationary period, their license will be revoked, and they must undergo the entire learning process and retake the driving test. If the 12-point threshold is exceeded after the probationary period, the driver must attend a 7-day training course and retake Subject 1. Below are the details: 1. If a motor vehicle driver accumulates 12 penalty points within a scoring cycle, they must report to the traffic management department of the public security authority at the place where the driver's license was issued or where the violation occurred within 15 days to receive a 7-day education program on road traffic safety laws, regulations, and related knowledge. 2. After completing the education program, the vehicle management office must administer the Subject 1 test within 20 days.

What are the components of a car air conditioning system?

An automotive air conditioning system is generally composed of a compressor, condenser, evaporator, expansion valve, receiver-drier, pipes, and other components. Here is relevant information: 1. The car air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle. It provides a comfortable environment for passengers, reduces driver fatigue, and improves driving safety. The air conditioning system has become one of the indicators to measure whether a car is fully equipped. 2. Compressor: The compressor is the "heart" of the air conditioning refrigeration system. It is a power source that circulates the refrigerant within the system. Its function is to compress the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure refrigerant, completing the transformation process from gas to liquid.

Can I Take the Driving Test on Weekends?

No, the driving test is conducted at the driving test center, which follows the national statutory holidays for rest. The driving test center is under the jurisdiction of the traffic police, who are governed by the Ministry of Public Security, which in turn is managed by the government. In May 1995, China implemented a six-day workweek system. Although tests cannot be taken on weekends, driving schools remain open for practice sessions. Currently, there are four subjects in the driving test. Below is an introduction to each subject: 1. Subject 1 primarily assesses basic knowledge of road traffic safety laws and regulations, traffic signals, and driving rules. It also includes content on safe and civilized driving requirements, safe driving skills in complex conditions, and emergency handling, which were previously part of Subject 1 but are now separated as the safe and civilized driving knowledge test in Subject 3, conducted after the actual road driving test. 2. Subject 2 includes five mandatory test items: reversing into a parking space, starting on a slope and stopping at a designated point, parallel parking, curve driving, and right-angle turns. 3. Subject 3 covers preparations before starting, starting, passing intersections, obeying traffic signals, driving according to road markings, changing lanes, meeting other vehicles, overtaking, and stopping at designated points. It includes 16 road driving skills: preparation before starting, starting, driving straight, changing lanes, passing intersections, pulling over, crossing pedestrian crossings, passing school zones, passing bus stops, meeting other vehicles, overtaking, making U-turns, night driving, shifting gears, turning left at intersections, and turning right at intersections. 4. Subject 4 is the safe and civilized driving knowledge test, which focuses on safe and civilized driving requirements, safe driving knowledge in adverse weather and complex road conditions, emergency handling methods such as tire blowouts, and post-accident procedures. This written test is conducted within one day after passing the road test and can be taken an unlimited number of times for free.
