Manufacturer summary

Original wording in English

This bulletin announces availability of reprogramming files to optimize the engine’s electronic control module (ECM). These new files address concerns of the check engine light coming on and setting any of the following DTCs for Air-Fuel Ratio Imbalance: P219C, P219D, P219E or P219F. The ECM parameters for air-fuel (A/F) calculation have been revised.

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.
