Conditions for clearing the fuel fill cap caution

  1. When the fuel fill cap caution is displayed by the first drive cycle leak judgment (Pending DTC stored) at a 0.02 inch leak or a 0.09 inch leak, the fuel fill cap caution goes out when the next failure occurs (second drive cycle) and P0457 is stored. (MIL illuminates)
  2. When no leak is judged by a 0.02 inch leak or a 0.09 inch leak after the fuel fill cap caution is displayed, the fuel fill cap caution goes out the next time the ignition switch is turned to ON (II). (P0457 is not stored at this time)
  3. When driven three times without this failure detected and a 0.02 inch leak or a 0.09 inch leak detection is not done after the fuel fill cap caution is displayed, the fuel fill cap caution goes out. (P0457 is not stored at this time)
  4. Use the Clear command of scan tool to erase the caution. The caution is erased when the MIL is illuminated.
