ISSUE
The Malfunction Indicator Lamp (MIL) may be illuminated and Diagnostic Trouble Codes (DTCs) P1381 and/or P1383 may be stored in memory. The
vehicle may also have a rough idle or reduced power condition, and/or may stall at an idle. This may be caused by:
^
Variable Camshaft Timing (VCT) control system stuck with a machining chip.
^
VCT hollow oil feed bolt being plugged with debris.
ACTION
Refer to the following Service Procedure for diagnostic and repair procedures.
To address the Issue, valve timing must be corrected by this procedure to cycle the VCT solenoid so that it frees the stuck valve and flushes the
machining chip to the oil filter.
