P1349 TOYOTA Description
Variable Valve Timing (VVT) system controls the intake valve timing to proper timing in response to the driving conditions. The Engine Control Module (ECM) controls Oil Control Valve (OCV) to make the intake valve timing properly, and, oil pressure controlled with OCV is supplied to the VVT controller, and then, VVT controller changes relative position between the camshaft and the crankshaft. The P1349 code is triggered when the valve timing does not change from current valve timing or the current valve timing is fixed.
