If the seat belt sensor is broken, the airbag alarm will go off. While driving, the airbag warning light often remains illuminated. The possible causes of this fault are as follows: Communication error: It could be due to a loose connection in the sensor socket or the computer socket. Check whether the wiring harness from this sensor plug to the airbag computer is normal. After disconnecting the negative terminal of the battery for one minute, unplug the airbag sensor connector. Use the ohm setting to measure the wiring harness from the airbag sensor plug to the airbag computer. No short circuit or high resistance was found. Due to safety reasons, the airbag components cannot be measured with a multimeter. Short circuit in the side airbag system power supply: For the side airbag component inspection, it is still not possible to measure directly with a multimeter. However, components with equal resistance can be used to replace the side airbag components, providing the computer with a substitute value.

Is Rust on the Car Steering Column Normal?

Rust on the car steering column is a normal phenomenon. Here are the relevant explanations: 1. Rust protection: The steering column generally does not have paint coverage for rust protection, so after some time of use, a layer of rust will appear on the steering column. This is quite common for most mid to low-end cars. Even some high-end cars do not spend money on treatment because these parts are not directly visible to the car owner and pose no safety hazards, so many manufacturers do not treat the steering column. 2. Steering column: The steering column is the component that connects the steering wheel and the steering gear in the steering system. Through the steering column, the driver transmits torque to the steering gear, driving the steering gear to achieve steering. Common steering columns include hydraulic power steering columns, electro-hydraulic power steering columns, and electric power steering columns, each with different systems.

What is a PVC Valve?

Car's PVC valve is a device in the forced ventilation system of the automobile engine's crankcase, composed of valve body, valve, valve cover, and spring. The following are the impacts of a faulty PVC valve on the vehicle: 1. The engine may shake during operation, with unstable idling, and a large amount of white smoke may emerge from the exhaust pipe. 2. Since it is located inside the crankcase, when it fails, it may cause internal corrosion, accelerate wear, and further shorten the engine's service life. 3. The engine may become difficult to start and exhibit poor acceleration. 4. Damage to the PVC valve can also lead to easy sedimentation and blockage of sludge. The blockage of sludge increases the pressure in the crankcase, causing oil and gas to flow back into the air filter, ultimately resulting in contamination and damage to the air filter.

What does it mean when the p light keeps flashing?

The p light in a car is the brake system warning light, also known as the parking brake warning light. When the p light comes on, it indicates that there is a fault in the car's braking system. In such cases, the car should be pulled over immediately for inspection to avoid potential safety hazards. Below is an analysis of situations when the p light comes on: 1. Computer issue: When the car is initially powered on, the onboard computer performs a self-diagnosis check. During this time, all warning lights on the dashboard will illuminate. Once the check is complete, the warning lights will turn off. This is a normal phenomenon and does not require attention. However, if the warning lights remain on after the computer completes its self-diagnosis, it indicates a fault, and the car should be inspected and repaired as soon as possible. 2. Fault occurrence: If the brake system warning light comes on while driving, it means there is a fault in the car's braking system. This could be due to damaged brakes or the parking brake not being fully released. In such situations, the car should be pulled over for inspection to prevent any safety risks.
