P0442 - EVAP CONTROL SYSTEM LEAK DETECTED (SMALL LEAK)

Description:	The PCM monitors the complete EVAP control system for the presence of a small fuel vapor leak. System failure occurs when a fuel vapor leak from an opening as small as 1.016 mm (0.040 in) is detected by the EVAP running loss monitor test.
Possible Causes:	After-market EVAP hardware (such as fuel filler cap) non-conforming to required specifications. Small holes or cuts in the fuel vapor hoses/tubes. Canister vent solenoid stays partially open on closed command. Damaged, missing or loosely installed fuel filler cap. Loose fuel vapor hose/tube connections to the EVAP system components. EVAP system component seals leaking (EVAP canister purge valve, fuel tank pressure sensor, canister vent solenoid, fuel vapor control valve tube assembly or fuel vapor vent valve assembly).
