The P0456 code for a Jaguar S-Type indicates a small leak in the evaporative emission control system (EVAP). This system is responsible for capturing and recycling fuel vapors from the fuel tank to prevent them from escaping into the atmosphere. A small leak may be caused by a loose or damaged gas cap, a cracked EVAP hose, or a faulty EVAP component. Addressing this issue typically involves checking for leaks and ensuring that all components are functioning correctly.
