The engine yellow light appearing on the car dashboard indicates an engine malfunction that requires immediate repair. The engine fault light illuminates due to sensor issues, which include the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, oxygen sensor, etc. When these sensors are damaged or have poor contact, the ECU cannot accurately obtain engine data, causing the fault light to illuminate. Engines have specific maintenance cycles, and failure to perform timely maintenance can increase the engine's load. Combined with poor driving habits, this can lead to engine malfunctions.

I've been driving for so many years, and it's common to see the yellow engine light on the dashboard. Don't panic too much, it's not a big deal; the red light is what you should worry about. Last time my car had this issue, I first got out and checked if the fuel cap was tightened properly. Sometimes after refueling, if you forget to close it properly, it triggers an alarm. Then I listened for any unusual noises or vibrations from the engine. If there were any, I would have immediately found a safe place to stop and called for assistance. If not, you can continue driving, but keep your speed moderate to avoid high speeds and get to a repair shop as soon as possible. Just plug in an OBD diagnostic tool, and it will show the specific trouble code, like an oxygen sensor fault or spark plug issue. A quick fix will do the trick. I also do regular maintenance to prevent these minor issues. After all, older cars are more prone to problems. I remember last time when I changed the oil, the mechanic also suggested checking the electrical system and stuff—pretty useful advice.

How long does it take to complete the driver's license test according to regulations?

The driver's license test must be completed within three years. Below is more information about the driver's license test: 1. The validity period of the driver's license test is three years, starting from the date of passing the subject one test. The remaining subjects must be completed within three years. 2. Applicants for a motor vehicle driver's license must pass four subjects: the subject of road traffic safety laws, regulations, and related knowledge (subject one), the subject of field driving skills (subject two), the subject of road driving skills (subject three), and the subject of safe and civilized driving knowledge (subject four). 3. If subject one has not been taken, there is no concept of exceeding the validity period. If the contract signed with the driving school stipulates a validity period, the driving school will generally require students who exceed the time limit to pay an extension fee.

How to use the WEY VV6 electronic gear lever?

WEY VV6 electronic gear lever operation method is as follows: 1. When the ignition switch is in ON mode and the engine is not started, gear shifting is only possible between N (Neutral) and P (Park) positions. When the vehicle speed is below 2 km/h, opening the driver's door or turning off the engine will automatically shift the vehicle to P position. 2. Engaging P position: When the vehicle is stationary, press the parking gear button. (To avoid vehicle damage or accidents, ensure the vehicle is completely stopped before shifting to P or R positions.) Always depress the brake pedal before starting the vehicle, otherwise the vehicle may move automatically if the gear lever is in a driving position. 3. Briefly push the gear lever in the desired direction, surpassing the pressure point if necessary, then release it to automatically return to the center position. To disengage P position or engage R (Reverse) position, depress the brake pedal and press the unlock button; to engage D (Drive) position, depress the brake pedal. 4. After engaging D position, pulling the gear lever backward switches to M (Manual) position; pulling it backward again switches back to D position. The currently engaged gear will be displayed on both the gear lever and the instrument information center.

What are the precautions for making a left turn while driving?

Precautions for making a left turn in a vehicle are as follows: 1. Try to make the turn as wide as possible to avoid obstruction or collision with other hazards. 2. Check the rearview mirror while turning to ensure there are no vehicles or pedestrians behind or to the side. 3. Be aware of blind spots during the turn to avoid hitting the curb or causing a scrape. Before turning, always check for obstacles below the rearview mirror; if necessary, open the door to take a look before proceeding. 4. Maintain control of the steering wheel. Proper steering control is crucial when turning. For a tight turn, turn the steering wheel as much as possible and gradually straighten it after completing the turn; for a wide turn, steer slowly.

Should You Use Internal or External Air Circulation When Turning on the AC?

The best practice when turning on the AC is to alternate between internal and external air circulation. Although using internal circulation in summer is more fuel-efficient and provides the best cooling effect, prolonged use can lead to "air conditioning sickness," especially when idling in the car with the AC on, which may cause carbon monoxide poisoning. Below is an introduction to the two air circulation modes: 1. Internal circulation: The air blown by the blower circulates only inside the car. Since no external air is involved, internal circulation is fuel-efficient and cools (or heats) quickly, but the downside is that it hinders air renewal inside the car. 2. External circulation: The blower draws air from outside the car and blows it inside. The advantage is that external circulation maintains fresh air inside the car, but it consumes more fuel and cools (or heats) more slowly.

What Are the Effects of Overfilling Engine Oil?

Overfilling engine oil can have the following specific effects on a vehicle: 1. Oil may enter the combustion chamber through the gap between the cylinder and piston, leading to carbon buildup. 2. It increases the stirring resistance of the crankshaft and connecting rod, resulting in higher fuel consumption. 3. It may cause oil leakage. Below are some key points about adding engine oil: 1. Adding too little oil can reduce lubrication effectiveness, leading to severe engine wear and potentially causing cylinder scuffing; it may even shorten the engine's lifespan. 2. To maintain the lubrication system, the most important step is to regularly change the engine oil; it is best not to simply add oil. If oil is added frequently over time, it can lead to excessive buildup of sludge and carbon deposits inside the engine, clogging the oil pickup screen and preventing proper lubrication of engine components, which can severely damage engine parts.

What Causes Difficulty in Starting a Car?

The reasons for difficulty in starting a car are as follows: 1. Weak spark plug ignition energy: Not replacing spark plugs after their maintenance cycle can lead to a severe drop in ignition energy, making the car hard to start. 2. Severe carbon buildup in the car: Excessive carbon deposits inside the engine can cause the fuel injectors to spray gasoline that gets largely absorbed by the carbon deposits, resulting in difficulty starting. 3. Insufficient battery power: Low battery power reduces engine power, making it difficult to start the vehicle. 4. Clogged exhaust pipe: A clogged exhaust pipe leads to an overly lean air-fuel mixture during startup, causing difficulty in starting the car. 5. Faulty fuel pressure regulator: The fuel system's pressure directly affects the air-fuel mixture concentration. If the car is hard to start, the fuel pressure should be checked first, and the fault location can be determined by inspecting the fuel pressure regulator. 6. Incorrect engine timing: Incorrect engine timing can prevent the car from starting.
