How to Report Vehicles Driving on the Highway Emergency Lane?

What Causes the Malfunction Light to Illuminate, Lack of Power When Accelerating, and Inability to Gain Speed?

Poor quality gasoline that does not meet standards, faulty oxygen sensor, malfunctioning air flow sensor, carbon buildup on spark plugs, engine knocking, or engine misfiring. Related explanations: 1. Carbon buildup on spark plugs: Leads to poor engine performance, resulting in unstable idling, poor acceleration, increased fuel consumption, and other abnormal phenomena. 2. Air flow sensor: Detects the intake air and converts it into an electrical signal sent to the electronic control unit (ECU), allowing the ECU to determine how much fuel to inject. 3. Oxygen sensor: Since the purification capability of the three-way catalyst for CO, HC, and NOX sharply decreases once the air-fuel ratio deviates from the theoretical value, an oxygen sensor is installed in the exhaust pipe to detect the oxygen concentration in the exhaust and send feedback signals to the ECU. The ECU then adjusts the fuel injector's fuel injection volume accordingly, keeping the air-fuel ratio close to the theoretical value.

How to Repair a 12V Battery After It Runs Out of Power?

12V battery repair method after power loss: 1. Open the battery cover and remove the 6 safety caps; 2. Use a syringe to fill each hole with distilled water. If it's a 1.28 standard electrolyte, the plates may burn due to excessive acid concentration, and the acid in the battery will not evaporate. What's missing is water, so just add about 20 to 30ml of distilled water to each small hole; 3. After filling, let the battery sit for half an hour to allow the sponge around the plates to fully absorb the water, then use a resistor to discharge all the electricity from the battery; 4. After discharging, charge the battery. A pulse charging method can be used because it effectively removes plate sulfation and increases battery capacity; 5. After charging is complete, use a syringe to extract excess water from each hole; 6. Put the caps and cover back on, and the battery is ready for use in the vehicle.

How many days does it take to replace a bumper at a 4S shop?

Replacing a car bumper at a 4S shop takes 3 to 4 days. The main function of the front and rear bumpers is to absorb external impact: The main function of the front and rear bumpers is to absorb external impact, effectively protecting the vehicle body and serving as a safety device for passengers. When vehicles were first introduced, bumpers were primarily made of metal. With the continuous development of the automotive industry, bumpers have been replaced with plastic materials, which serve to protect both the vehicle and pedestrians. Specific time for bumper replacement: Replacing a car bumper at a 4S shop takes 3 to 4 days. The process involves painting the bumper, which can be completed on the same day. However, it then requires 2 to 3 days for the paint to fully dry before the vehicle can be used normally. In winter, this period may be extended by 1 to 2 days.

Is Automatic Transmission Subject 2 or Subject 3 Harder?

Subject 2 tests precision and basic skills, while Subject 3 tests procedures and flexibility. Many people think Subject 3 is harder because it involves driving on the road. However, in actual exams, Subject 2 tends to be more challenging. The reasons are as follows: 1. Challenges of Subject 2: Subject 2 has too many test items, and since it is the first time most people take the in-car test during the entire exam process, many feel nervous. Additionally, due to various reasons related to the test vehicle, visibility and handling are difficult to control, and the overall structure is unfamiliar. Especially when reversing into the parking space, it's easy to cross the solid line by accident. This tests the examinee's ability to adjust the seat height and rearview mirror angle properly before moving. 2. Subject 3 is about details determining success: Don’t resent the coach for being strict, because during the exam, you’ll find that listening to the coach is absolutely the right thing to do.

Can the ETC be directly transferred to a new car when selling the old one?

If the new car owner did not change the license plate when purchasing the car, and the original car owner had already registered for ETC elsewhere, and the new car owner wants to re-register for ETC, then the previously linked ETC must be canceled for the ETC device to function properly. ETC activation method: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth is on." If inserting and removing twice without the electronic tag attached shows "Tag invalid," this is normal and does not affect activation. Alternatively, you can press the button on top of the electronic tag to enable Bluetooth. Turn on the phone's Bluetooth, open the corresponding mobile app (usually there is a download QR code on the electronic tag), and enter the device activation interface. Click on device connection and wait patiently for the "Connection successful" prompt. Once connected, upload a photo of the vehicle's front to complete activation.

Does the Number of Passengers Include the Driver?

Does the Number of Passengers Include the Driver? The number of passengers includes the driver. Passenger transportation regulations stipulate: Sedans also fall under the category of passenger vehicles, so overloading a sedan will also result in penalties. The penalties for overloading a sedan are the same as for commercial passenger vehicles. According to the new traffic regulations, driving a commercial passenger vehicle (excluding buses) or school bus with passengers exceeding the approved capacity by less than 20%, or driving other passenger vehicles with passengers exceeding the approved capacity by more than 20%, will result in a 6-point penalty; driving a passenger vehicle other than a commercial passenger vehicle (excluding buses) or school bus with passengers exceeding the approved capacity by less than 20% will result in a 3-point penalty. Approved passenger capacity for sedans: Typically, the approved passenger capacity for a sedan is 5 people, but there may be instances of overloading.
