This is a garbled fault code, which requires a specialized decoder or switching to another system to read the correct fault code. Below is relevant information about automotive fault codes: 1. Meaning: Automotive fault codes are codes generated by the vehicle's computer ECU after analyzing a malfunction. Common fault codes are often caused by sensor failures or poor sensor performance. However, some mechanical faults cannot be read by the ECU. The car's dashboard may display some basic fault indications, but these are only a small part. The main method is to use a specialized instrument—a decoder—to read the codes. There are various types of decoders, such as X-431 and KT300, but their working principles and the fault codes they read are the same. 2. Classification: Fault codes are divided into real codes, historical codes, and intermittent codes. Real codes are easy to detect, historical codes refer to previously unresolved fault codes, while intermittent fault codes are not fixed.

What to Do About High Car Fuel Consumption?

Reasons and solutions for high car fuel consumption are as follows: 1. Clean engine carbon deposits: Excessive carbon deposits in the engine are a significant cause, mainly due to the use of inappropriate fuel. It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not obvious, it indicates a large amount of carbon deposits in the engine. In this case, the car must be taken to a 4S shop for professional technicians to clean the carbon deposits inside the engine. After cleaning, it is best to drive the car at high speed for a while, as this helps to increase displacement and allows stronger airflow to remove larger carbon deposit particles. 2. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. If the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gas while driving, and the oxygen sensor should be replaced at this time. 3. Regularly replace the three filters: During the use of the vehicle, the oil filter, air filter, and fuel filter should be replaced regularly. If not replaced for a long time, they will become dirty and affect performance, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits.

Can You Buy a Car in Stock at a 4S Store?

4S stores have cars in stock that can be purchased, but it is not recommended to pick up the car on the same day. The reasons are as follows: 1. Tight pickup time: Since 4S stores usually start receiving customers after 9 or 10 in the morning, and customers generally arrive at the 4S store relatively late, the time available to complete the purchase and pickup on the same day becomes very limited. This can easily lead to negligence in processes such as vehicle inspection and paperwork, and sometimes carelessness may result in serious consequences. 2. Car insurance not yet effective: Due to the effective period of car insurance, generally, the insurance purchased on the same day only takes effect at midnight the next day. Therefore, if a customer picks up the car on the same day of purchase and the vehicle is involved in a scratch or accident, all losses will have to be borne by the customer themselves.

Where to Obtain the Vehicle Inspection Exemption Label?

Vehicle inspection exemption labels can be applied for at the local vehicle management office without any fees. The vehicle owner must personally bring relevant documents, including the vehicle's driving license (original and copy), the ID card of the vehicle owner, the compulsory traffic insurance policy, and the tax payment or tax exemption certificate for vehicle and vessel tax. Here are the relevant details: 1. Definition of Vehicle Inspection Exemption: Vehicle inspection exemption means that for vehicles meeting the exemption conditions within 6 years, the on-site inspection process is waived. Owners only need to apply for the inspection label every two years and affix it to the vehicle as required. 2. Types of Vehicles Not Eligible for Inspection Exemption: ① Vehicles involved in accidents during this period, i.e., new vehicles involved in fatal accidents within 6 years, are not eligible for the exemption policy. ② Vans (referring to vehicles with 7 or more seats). ③ Vehicles that have not been registered for a long time after purchase are not eligible for exemption. For vehicles that have not been registered for more than 4 years since the date of manufacture, the original inspection rules apply, and they are not eligible for the exemption policy (still requiring inspection every 2 years within 6 years).

What does the low engine oil indicator look like?

The low engine oil warning light: Its shape resembles a teapot with a drop of liquid dripping down. When the engine oil replenishment indicator lights up, you should immediately take your car to a 4S shop for inspection and should not continue driving. Otherwise, it will accelerate engine wear and may cause irreversible damage to the engine itself. Here are some related details: 1. Engine oil filling standard: Engine oil should generally be filled to slightly above the middle point between the minimum and maximum marks on the dipstick, never exceeding the maximum or falling below the minimum mark. Exceeding the maximum mark will increase the rotational resistance of the engine crankshaft and affect performance, while falling below the minimum mark will prevent adequate lubrication protection for internal engine components. 2. Engine oil replacement cycle: Different manufacturers have varying requirements for oil change intervals. Generally, engine oil should be checked and replaced at a 4S shop every 5,000 kilometers/6 months. If you use fully synthetic oil, it can be replaced every 8,000 kilometers.
