What does engine EV control system failure mean?

[VanEloise]

This indicates that the ECU is damaged. The ECU is the engine's control computer, often referred to as the brain of the engine. Without the ECU, the car's engine cannot operate normally. If the ECU is damaged, it needs to be replaced directly. Below is additional information: Working principle: When the engine is running, sensors can feed data back to the ECU, which, after processing, can control the engine's operation through actuators. Without the ECU, the engine cannot function properly. The ECU is usually installed in the engine compartment and is encased in a metal shell that helps dissipate heat and protects the ECU. Precautions: The primary cause of ECU damage is water ingress. Electronic systems are most vulnerable to water, and driving through water can easily lead to water damage in the car's ECU and other electronic systems. If a car has been submerged in water, the ECU will almost certainly be water-damaged. If the ECU is damaged, it is necessary to purchase a brand-new original ECU for replacement.
