What are the causes of engine control system failure?

[DiEsther]

Engine control system failure indicates a damaged ECU. The causes of this failure include: 1. Power circuit failure; 2. Output power module failure; 3. Memory failure; 4. ECU water ingress and moisture damage. If the ECU is damaged, it needs to be replaced directly. More details are as follows: 1. ECU stands for Electronic Control Unit, which is essentially a specialized microcomputer controller for automobiles. It consists of a microprocessor, memory, input/output interfaces, analog-to-digital converters, and large-scale integrated circuits for shaping and driving. 2. The automobile engine is the device that provides power to the vehicle, acting as the heart of the car. It determines the vehicle's power, fuel efficiency, stability, and environmental performance. Depending on the power source, automobile engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others.
