Car chassis suddenly making a noise is caused by gear issues, loose connecting components, insufficient lubrication, and other reasons. Gear issues: The gear teeth of the drive wheel are broken or the surface is damaged. In this case, you should pull over to check. If the gear is damaged, it should be replaced with a new one promptly. Loose connecting components: The abnormal noise is caused by loose connecting components of the wheel. There are many gears in the wheel's transmission. If any of them are too loose, a noise will be heard when turning. The connecting components need to be tightened. Insufficient lubrication: In winter, many components are cold and hard, and the lubrication is insufficient, leading to abnormal noise. Additionally, when the drive wheel slips, do not suddenly accelerate, as this can cause the planetary gears to lock on their shafts. Appropriate lubrication oil should be added.

What are the oxygen sensor fault codes?

Oxygen sensor fault codes include: P0134 indicates no signal from the upstream oxygen sensor; P0135 indicates a fault in the heating circuit of the first sensor in the first group; P0141 indicates a fault in the oxygen sensor heater circuit. The oxygen sensor is a sensor that monitors exhaust gases, responsible for measuring the oxygen content in vehicle emissions. After the exhaust is emitted, if the air-fuel mixture is too rich or too lean, it sends a signal to the vehicle's computer to adjust the fuel supply. When the oxygen sensor fails, the exhaust warning light will activate, the engine emissions will become non-compliant, and the vehicle may experience reduced power. It is crucial to repair any oxygen sensor faults promptly.

Will running a red light with a temporary license plate be captured?

Temporary license plates will also be captured for running a red light. Whether it's a formal license plate or a temporary one, running a red light while driving a car is not allowed. If a car uses a temporary license plate and runs a red light, it will still be penalized. A temporary license plate is a paper motor vehicle license plate that permits temporary road use of the vehicle, also known as a temporary driving license plate. Temporary license plates are issued by the public security vehicle management department for newly purchased vehicles before formal registration.

How to Drive a Manual Transmission Car in Traffic Jams?

When driving a manual transmission car in traffic jams, you can only use the semi-clutch technique. Semi-clutch refers to the operation where the driver does not press the accelerator pedal while in first gear at idle speed, and controls the vehicle speed by adjusting the depth of the clutch pedal with the left foot. This technique is commonly used during vehicle startup and driving in congested areas. Automatic transmission cars do not have a clutch, so there is no semi-clutch operation; you simply need to place the gear lever in D (Drive) or shift to a low gear. A manual transmission is a gear-shifting device used to alter the speed and torque transmitted from the engine to the drive wheels. It provides different traction and speed under various driving conditions such as starting from a standstill, climbing hills, turning corners, and accelerating, while also keeping the engine operating within a more favorable range.
