Original wording in English

Improper Secondary Parameter judgement criteria may cause false MIL illumination during 3rd Oxygen Sensor Monitoring (P0145). This TSB provides a field fix procedure to address false MIL illumination with DTC P0145 (Heated oxygen sensor (3rd) circuit slow response) stored in the ECM. This software update optimizes the judgement criteria to minimize false MIL illumination.

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.
