Manufacturer summary

Original wording in English

This Preliminary Information communication advises the technician to follow this Preliminary Information if there is a diagnostic trouble code P00C6 and or P228C set and normal Service Information diagnostics didn?t lead to a repair. Technician is to recheck the terminals at the Engine Control module for fit and tension as well as the crimp to the wire. The engine control module terminals to inspect are in the X2 connector. Inspect terminal number 3, 18 and 19 for the fuel rail pressure sensor and in the X3 connector terminals 16 and 32 for the high pressure fuel pump. The diagnostic trouble codes could set with as little as a 2 ohm resistance reading on these circuits. If any concerns are found replace the affected terminals and verify the repair.

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.
