Manufacturer summary

Original wording in English

Service bulletin - The MIL comes on and DTC P0455 (EVAP system large leak) and/or DTC P0456 (EVAP system very small leak detected) is set. The fuel fill cap (gas cap) may also be loose or have a stick-slip feeling when tightened. The fuel fill cap gasket creates too much friction, preventing the cap from sealing properly.
