Here are the reasons why the fuel gauge does not respond after refueling: 1. For older vehicles, this is likely an issue with the fuel level sensor (also known as the fuel float). Check whether the fuel level sensor connector on the fuel tank is loose, oxidized, or corroded. Observe if there is any obstruction in the movement of the fuel level sensor. 2. If the fuel level sensor is functioning properly, the issue might be with the wiring of the fuel gauge on the dashboard. In this case, remove the dashboard and use a multimeter and a needle to test the corresponding fuel gauge wiring. 3. If the fuel gauge of a new car suddenly drops to zero and remains unresponsive, it indicates a problem with the sensor, which should be replaced directly at a 4S dealership.

What is the function of KDSS?

Kdss allows the suspension to extend during off-road driving, ensuring sufficient wheel travel for tire contact with the ground, thereby improving stability and passability. During highway driving, it suppresses suspension extension and twists the stabilizer bar to reduce steering tilt, enhancing handling and comfort. Information about KDSS is as follows: 1. Introduction: KDSS stands for Kinetic-Dynamic-Suspension-System, which translates to "Kinetic Dynamic Suspension System" in Chinese. 2. Structure: It is an electronically controlled kinetic dynamic suspension system. Both front and rear stabilizer bars have independent hydraulic cylinders for controlling vertical movement, connected by a hydraulic system. Each stabilizer bar's hydraulic cylinder is divided into upper and lower chambers, with the front upper and lower hydraulics connected to the rear upper and lower hydraulics via respective hydraulic pipelines. Each hydraulic pipeline contains an accumulator. KDSS controls each stabilizer bar in its optimal state by regulating a set of valves connected to the accumulators in the hydraulic pipelines.

How much over the speed limit is driving at 85 in an 80 zone?

Driving at 85 in an 80 zone is considered speeding, but since it does not exceed 10% of the speed limit, no points will be deducted or fines imposed. Below are specific details regarding speed regulations: 1. Speed regulations: The speed limit for small cars on highways is 120 km/h, while for trucks it is 100 km/h. In China, pickup trucks are classified under the truck category, with a maximum speed limit of 100 km/h on highways. 2. Speeding penalties: For small vehicles speeding less than 20%, a warning will be issued. Speeding between 20-50% will result in a 200 yuan fine and 3 penalty points. Speeding between 50-70% will lead to a 1000 yuan fine, 6 penalty points, and possible revocation of the motor vehicle driving license. Speeding over 70% will result in immediate revocation of the driver's license and a 2000 yuan fine.

What are the symptoms of a damaged diesel pump plunger?

Diesel pump plunger damage symptoms include: 1. False overspeeding refers to the diesel engine starting with normal idle speed, but failing to decelerate after releasing the throttle at high speed. This occurs when the injector plunger is worn, and the fuel rack is set to idle fuel quantity at the idle position. 2. No fuel flows from the high-pressure fuel line, but there is fuel in the low-pressure circuit, and the diesel engine fails to start, indicating the fuel supply rack is stuck in the no-fuel position. In this case, timely repair of the fuel injection pump is also required. 3. Fluctuating engine speed is a sign of inflexible fuel supply rack movement or excessive wear of internal governor components, leading to increased clearance. Therefore, the fuel injection pump also needs repair.

What is the throttle body matching method for the Cruze?

For the SAIC-GM Chevrolet Cruze, throttle body matching, also known as initialization, requires disconnecting the negative terminal of the battery for several minutes to allow the vehicle to enter a dormant state. During this process, the vehicle's onboard computer will reset its original memory to factory settings, and then the matching can be completed by restarting the vehicle. The specific steps are as follows: 1. Open the driver's door of the SAIC-GM Chevrolet Cruze. 2. Pull the hood release lever located on the left side of the driver's leg area. 3. Lift the engine hood upwards. 4. Secure the engine hood with the support rod to ensure it is firmly held and to prevent any hazards during the operation. 5. Disconnect the black negative terminal of the battery for more than 5 minutes to allow the vehicle to enter a dormant state. During this time, the onboard computer's original memory will be reset to factory settings. 6. Reconnect the negative terminal of the battery, turn the key, and start the engine to complete the matching process.

What Are the Effects of Water Entering a Car's Exhaust Pipe?

Water entering a car's exhaust pipe can potentially damage the catalytic converter, cause the exhaust pipe to rust through, or harm the oxygen sensor. Below are some maintenance tips for car exhaust pipes: 1. Regular inspection of the exhaust pipe: Generally, a comprehensive inspection of the exhaust pipe can be costly, and many car owners are reluctant to spend the money. It is advisable to visit a general repair shop for an initial check-up. The primary goal is to identify any damage. If a crack is found in the exhaust pipe, it must be repaired promptly to avoid affecting the vehicle's normal operation. During regular driving, pay attention to the sound of the exhaust pipe. If any unusual noise is heard, it might indicate loose fastening screws causing vibration, which should be addressed immediately to prevent further issues. 2. Preventing the muffler from rusting: The muffler is located in the middle of the exhaust system, so any problem with it can affect the entire exhaust system. The main preventive measure is to avoid water entering the muffler. Be cautious during rainy days or when washing the car to prevent water from entering the muffler. If water accidentally gets in, start the engine and let it idle for about 10 minutes to expel the accumulated water.

Should the Engine Be Turned Off While Waiting in the Car?

When waiting in the car for less than five minutes, it is acceptable to keep the engine running. However, for waits exceeding five minutes, it is advisable to turn off the engine. Prolonged idling can be harmful to the engine, especially in underground parking lots where extended idling should be avoided. Hazards of prolonged idling while waiting in the car: 1. Extended idling causes the engine temperature to drop too low, leading to incomplete fuel combustion, which can result in carbon buildup, clogged fuel injectors, and severe cases may cause piston rings to seize or even break. 2. During prolonged idling, poor fuel atomization can cause unburned atomized diesel to condense, washing down the cylinder walls and contaminating the lubricating oil, diluting and degrading its quality. This lack of proper lubrication increases wear on engine components. 3. Poor combustion during extended idling worsens engine emissions. If toxic gases enter the cabin, they can pose serious health risks to occupants.
