What does the yellow engine light mean?
1 Answers
When a car displays a yellow engine light, it indicates a fault in the vehicle's engine system. Normally, when starting the car, the onboard computer performs a self-check of the entire system, and all indicator lights will briefly illuminate. Once the startup is complete, the indicators should turn off. If the fault light remains on after the car has started, it requires inspection. Below are common car faults: 1. Brake failure: When applying the brakes while driving, the car fails to slow down or stop; after one or multiple continuous brake applications, the brakes suddenly become ineffective. Possible causes include brake fluid or air leakage in the brake lines, broken or detached pipe connections, or failed brake sealing components. 2. Poor parking brake: After engaging the parking brake, the car easily starts moving or slides when parked on a slope. Possible causes include improper adjustment, uneven surface of the brake disc (drum), severe wear or contamination of the brake friction pads. 3. Brake drag: The brakes continue to engage after releasing the brake pedal, making it difficult to start the car, reducing driving power, causing the brake drum to overheat, and shortening the coasting distance. Possible causes include excessively small gaps in brake components, failed return springs preventing the brake shoes from retracting, or corrosion in the brake operating mechanism making retraction difficult.
