What model year is your Explorer? A few typical items that can cause this code, according to the 2002 Factory service manual, are:
  • Aftermarket EVAP hardware (such as fuel filler cap) non-conforming to required specifications
  • Small holes or cuts in fuel vapor hoses/tubes
  • Canister vent solenoid stays partially open on closed command
  • Damaged, cross-threaded or loosely installed fuel filler cap
  • Loose fuel vapor hose/tube connections to 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)
