These leaks often occur in hoses or valves between the air filter and the fuel tank. The P0442 code signifies that the vehicle does not meet emission standards and that fuel vapors may be leaking into the atmosphere. In such cases, it is recommended to have the vehicle's emission system checked by an automotive service center.
