Here are the reasons why the car doesn't move in D gear and only moves when accelerating: 1. Throttle opening too small: It may be due to insufficient throttle opening of the engine or inadequate fuel injection from the injectors. 2. Transmission signal issues: It could be related to problems with the transmission control system or actuator signals, causing the shift valve to be unresponsive and failing to engage properly, thus preventing the oil passage from opening. 3. Principle: Normally, most automatic cars (especially older models without AUTOHOLD function) will slowly move forward at idle speed after starting the engine, pressing the brake, shifting to D gear, and releasing the brake (similar to manual transmission in 1st gear), but at a very low speed. The car will only accelerate when the throttle is pressed further.

What Are the Hidden Functions of Car Keys?

In addition to the daily use of locking and unlocking the vehicle, car keys also have some hidden functions, mainly in five scenarios: 1. Window closing function after turning off the engine. For drivers who have already exited the vehicle, pressing or holding the lock button can automatically close the windows. 2. Automatic trunk opening. Many keys have a trunk button; pressing and holding or double-clicking the trunk unlock button can automatically open the trunk. 3. Remote window opening. 4. Opening a single door. Pressing the unlock button can open only the driver's door, while other doors remain locked. 5. The small piece of paper on the car key. This serves as proof for key replacement in case the key is lost.

What Are the Reasons for a Car Not Starting in Winter?

In winter, if a car fails to start, it can be analyzed from four aspects: spark plugs, oxygen sensors, throttle and intake passages, and fuel injectors: 1. Spark Plugs: During operation, especially in winter, symptoms like reduced power, engine shaking, and difficulty starting may occur. This could be due to carbon deposits on the spark plugs or loose ignition coils, leading to starting difficulties. Simply replacing the spark plugs can resolve this issue. 2. Oxygen Sensor: If the oxygen sensor is faulty, it can cause inaccurate fuel injection, resulting in a suboptimal air-fuel ratio in the engine. A significant deviation from the optimal ratio can make the engine hard to start. 3. Throttle and Intake Passages: Dirty throttle and intake passages can also lead to carbon buildup and blockages. In summer, this might manifest as noticeable shaking at idle, while in winter, it can cause difficulty starting the engine. 4. Fuel Injectors: Carbon deposits clogging the fuel injectors or impurities blocking the fuel pump's filter can both lead to the car not starting or having difficulty starting in winter.

Does an eight-year-old car require an annual inspection?

An eight-year-old car requires an inspection every two years. The Ministry of Public Security issued new regulations for vehicle inspections in 2021, stipulating that for vehicles older than 6 years but less than 10 years, the inspection cycle has been relaxed from once a year to once every two years. This means that private cars only need to undergo two on-site inspections within 10 years, specifically in the 6th and 8th years. Below is relevant information: Introduction: Vehicle inspection refers to a mandatory test for all vehicles that have obtained official license plates and registration certificates. It is equivalent to an annual physical examination for the vehicle based on the technical conditions for safe operation of motor vehicles. Vehicle inspections can promptly eliminate potential safety hazards, encourage enhanced vehicle maintenance, and reduce the occurrence of traffic accidents. Purpose: Vehicle inspections can promptly eliminate potential safety hazards, encourage enhanced vehicle maintenance, and reduce the occurrence of traffic accidents.

How to Deal with ETC Overcharging Issues?

Solutions for ETC overcharging issues: Visit the bank for consultation and resolution. First, print out the transaction details and travel records of your personal ETC card, then carefully verify each fee item. If incorrect charges are confirmed, you can request a refund from the bank. Precautions for ETC usage: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, maintain a distance of over 10 meters to prevent automatic fee deduction for the vehicle in front, in case its ETC device is faulty or absent. The ETC lane recognizes vehicle speeds up to 20km/h. Speeding may result in failure to read the vehicle's device information and unsuccessful fee deduction. Unauthorized removal or movement of the OBU device, detachment, or loosening of the ETC electronic tag can render the tag invalid. It can be taken to the bank where the ETC card was issued or to a highway service center for inspection. If the detachment or loosening is not due to human intervention, reactivation may suffice. When using a debit card linked to ETC, insufficient balance can lead to fee deduction failure. Follow the guidance of on-site staff to use the manual MTC lane with cash or card payment. Excessively thick car windshields may cause poor signal reception. This is particularly important for vehicles that have had their windshields replaced after accidents or for those with modified front windshields.
