Vehicle steering wheel warning light illumination may be caused by: 1. Excessive air in the power steering system, resulting in abnormal steering; 2. Foreign matter in the steering hydraulic pipeline causing the steering pump flow control valve to stick; 3. Loose connections in the power steering system leading to steering fluid leakage; 4. Excessive wear of the steering gear piston cylinder, poor oil seal sealing, or control valve sticking/damage. Solutions: 1. Inspect steering gear, steering pump control valve, oil reservoir filter, and steering fluid, then clean the entire power steering system; 2. Check tire pressure and refill if low; 3. Examine all oil pipe connections and tighten mounting bolts; 4. Replace oil pipes, power steering pump, or steering gear as needed.

What Impact Does an Electronic Throttle Accelerator Have on a Car?

An electronic throttle accelerator has no negative impact on a car. The output values of an electronic throttle accelerator are typically within the engine's rated power, posing no harm to the vehicle. The electronic throttle control system mainly consists of the throttle pedal, pedal displacement sensor, ECU, data bus, servo motor, and throttle actuator. The characteristic of an electronic throttle accelerator is to amplify the throttle signal for faster acceleration and improved dynamic response. When the throttle pedal is pressed, the accelerator calculates the rate of change of the throttle signal based on the degree and duration of the pedal press. A faster rate of change indicates a stronger demand for acceleration, and the throttle accelerator will amplify this rate of change accordingly.

Can I stop and wait for the green light in a variable lane when the light is red?

Yes. Relevant explanation is as follows: Introduction: When right turn and straight ahead are on the same lane (variable lane), right-turning vehicles can pass at any time regardless of whether the light is red or green. Straight-going vehicles must wait for the green light to pass straight through this lane. When the red light is on, straight-going vehicles are prohibited from entering the variable lane to stop and wait (parking is prohibited in this variable lane), otherwise it will be treated as a violation. Legal basis: Article 26 of the Road Traffic Safety Law of the People's Republic of China mentions that traffic signals consist of red, green and yellow lights. The red light means prohibition of passage, the green light means permission to pass, and the yellow light means a warning.
