Manufacturer summary

Original wording in English

SOME VEHICLES MAY EXPERIENCE A CHECK ENGINE LIGHT ON WITH DTCS P0011:00 AND/OR DTC P0012:00 STORED IN MEMORY. • P0011:00: ELECTRIC VARIABLE VALVE TIMING CONTROL SYSTEM - (OVER-ADVANCED) • P0012:00: ELECTRIC VARIABLE VALVE TIMING CONTROL SYSTEM - (OVER-RETARDED) THIS CONCERN MAY BE CAUSED BY VARIABLE VALVE TIMING (VVT) ACTUATOR SPRING SHAFT FATIGUE. DURING VEHICLE USAGE, THE SPRING SHAFT MAY FAIL AND CAUSE INCORRECT VVT OPERATION AND CHECK ENGINE LIGHT ILLUMINATION. THE INSPECTION PROCEDURE HAS BEEN IMPROVED TO ELIMINATE THIS CONCERN IN THE FUTURE.

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.
