Replacing the engine wiring harness does not require removing the engine. If the engine wiring harness is damaged, it is directly replaced. A faulty engine wiring harness can cause inaccurate signals, leading to the vehicle's inability to start and potentially even causing a fire. The wiring harness is the main component of a car's electrical network—without it, the car's electrical circuits would not exist. When a part of the car's electrical system malfunctions, abnormal phenomena such as smoke, sparks, unusual noises, burning smells, and high temperatures may occur. By using human senses—listening, touching, smelling, and looking—you can conduct an intuitive inspection of the car's wiring harness and electrical components to quickly identify the faulty area, significantly speeding up the repair process.
