Here are the solutions for P1101 intake air flow system performance malfunction: 1. Check if there is any air leakage in the pipeline between the air flow meter and the throttle, and whether the air filter is excessively dirty. If not, the air flow meter may be damaged; 2. Disconnect the coolant temperature sensor plug and the engine control module plug, then measure the resistance between these two disconnected wires. The resistance is generally below 10 ohms, or around 0.1 to 2 ohms; 3. The engine coolant temperature sensor temperature is too low. Additional information: The function of the Mass Air Flow (MAF) sensor is to convert the air flow into an electrical signal and send it to the Electronic Control Unit (ECU), serving as one of the fundamental signals for determining the fuel injection quantity.

What is the fuel consumption of the Changan CS35?

Changan CS35's official fuel consumption is 5.9L, which is relatively high. Additional information: The reasons for the high fuel consumption of the Changan CS35 are as follows: Engine carbon deposits: When the engine has carbon deposits and is not cleaned in time, the car's fuel consumption will increase. Spark plug failure: When the spark plug fails, it will slow down the car's acceleration, thereby increasing fuel consumption. Abnormal tire pressure: When the tire pressure is abnormal, the impact on fuel consumption is immediate, because the friction increases, so the fuel consumption increases. Poor fuel injector atomization: Poor fuel injector atomization can lead to clogging, thereby increasing fuel consumption. Sensor failure can cause continuous fuel injection, thereby increasing fuel consumption.

What grade of gasoline should the Xingyue use?

The Geely Xingyue uses 92-octane gasoline. This model offers two variants: the gasoline version uses 95-octane gasoline, while the gasoline + 48V mild hybrid system uses 92-octane gasoline. Relevant details are as follows: Reasons for using 92-octane gasoline in the Xingyue: 95-octane gasoline has a higher isooctane content and is designed for engines with higher compression ratios. The Geely Xingyue, a compact SUV under Geely Auto Group, has a relatively lower engine compression ratio. Using 95-octane gasoline may result in incomplete combustion, leading to waste as unburned fuel exits through the exhaust. Therefore, the Geely Xingyue is better suited for 92-octane gasoline. Differences between 92-octane and 95-octane gasoline: The main differences between 95-octane and 92-octane gasoline lie in compression ratio requirements, octane ratings, and pricing. The composition of n-heptane and isooctane varies between the two: 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane.

What is the fuel tank capacity of the Sonata in liters?

The currently available Sonata has 5 models, all with a fuel tank capacity of 60 liters. The vehicle is equipped with two types of engines: a 2.0-liter turbocharged engine and a 1.5-liter turbocharged engine. The entire lineup uses either an 8-speed automatic transmission (AT) or a 7-speed dry dual-clutch transmission (DCT), and all models feature front-wheel drive. Among vehicles in the same class, the Malibu XL 2022 model has a fuel tank capacity of 55 liters, while the K5 Kai Ku 2021 model has a fuel tank capacity of 60 liters. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by car manufacturers is measured from the bottom of the tank to the safe fill level, and there is additional space from the safe fill level to the tank opening. This space is reserved to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the instrument panel, which is marked with 'E' and 'F'. When the needle is close to 'E', it indicates low fuel, while nearing 'F' means the tank is nearly full.

Which Country Does GAC Toyota Belong To?

To be precise, GAC Toyota cannot be categorized by country. It is a 50-50 joint venture in China between GAC Group and Toyota Motor Corporation. Strictly speaking, most of its components are domestically produced by Chinese workers, representing a combination of Chinese labor and resources with Japanese technology, brand, and management. The differences between GAC Toyota and FAW Toyota are as follows: Different Vehicle Positioning: Compared to GAC Toyota, FAW Toyota is more upscale, featuring high-end models such as the Prado and Crown. Additionally, luxury vehicles priced above 500,000 RMB are manufactured by FAW Toyota. Different Establishment Times: FAW Toyota was established earlier than GAC Toyota. FAW Toyota was founded in 2000, while GAC Toyota was established four years later. The gap in establishment time can significantly impact various aspects of an automaker, such as manufacturing experience and market opportunities, creating certain disparities. Different Shareholding Mechanisms: FAW Toyota is controlled by FAW Group, whereas GAC Toyota is a 50-50 joint venture between GAC and Toyota. As a result, GAC Toyota enjoys more harmonious cooperation, while FAW Toyota has less decision-making authority in its partnership compared to GAC Toyota. Different Company Scales: FAW Toyota not only predates GAC Toyota in establishment but also had higher registered capital at inception. FAW Toyota's registered capital was 3.3 billion RMB, while GAC Toyota's was only 1.6 billion RMB. Due to fewer production lines, GAC Toyota's annual output is only about half that of FAW Toyota.
