Will the ECU be damaged if it gets wet?

ECU will be damaged if it gets wet. Moreover, once the ECU is damaged, it cannot be repaired and must be replaced with a brand-new one. Relevant information is as follows: 1. There are many sensors and actuators on the engine. The ECU can collect data from the sensors, process it, and then control the engine operation through the actuators. 2. Both the ECU and TCU are usually installed in the engine compartment, so avoid using a high-pressure water gun to directly rinse the engine compartment during regular car washing, as this may damage the ECU and TCU. Cars equipped with automatic transmissions also have a TCU, which is the computer for the automatic transmission. The TCU can also collect data from various sensors, process it, and then control the automatic transmission's gear shifting through the actuators.
