Original wording in English

Customers may notice the service engine soon (SES) lamp illuminate or was illuminated and turned off. DTC?s P0106 and P0108 may also be present as active or stored in history. Dealers will replace the MAP sensor.

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.
