Manufacturer summary

Original wording in English

Some vehicles may experience a check engine light on with DTC P0172:00 stored in the PCM memory. This normally occurs during the fast idle immediately after starting the engine or after the fast idle lowers to a normal idle. DTC P0172:00 - Fuel trim system too rich. Due to improper PCM control logic, the fuel injection amount may be improperly compensated when the engine start is not smooth and due to low quality fuel.

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.
