Manufacturer summary

Original wording in English

Some vehicles may exhibit the check engine light on with DTC P0456 stored in the PCM memory. P0456: EVAP system leak detected (very small leak). The concern is most likely the result of the customer not getting the fuel cap completely closed after fueling the vehicle. This causes a small fuel vapor leak and turns DTC P0456 on.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
