Manufacturer summary

Original wording in English

Service Bulletin - The MIL comes on with DTC P0139 (secondary heated oxygen sensor slow response) due to the ECM/PCM misinterpreting the secondary heated oxygen sensor output and sets DTC P0139.

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.
