• A self-diagnosis module for tank leakage detection is an essential component within a vehicle€™s evaporative emissions control system, helping monitor the integrity of the fuel system and detect leaks that could allow harmful fuel vapors to escape into the atmosphere. Modern vehicles are equipped with sophisticated evaporative emissions systems designed to capture and contain fuel vapors generated inside the fuel tank. The self-diagnosis module continuously monitors the sealed fuel system and works with the engine control unit (ECU) to identify leaks, pressure irregularities, or system malfunctions that may affect emissions performance, fuel efficiency, or overall vehicle operation. Fuel vapors created inside the tank are normally stored within the ev
