DESCRIPTION

In the VVT (Variable Valve Timing) system, the appropriate exhaust valve open and close timing is controlled by the ECM. The ECM performs exhaust valve control by performing the following: 1) controlling the exhaust camshaft, camshaft timing oil control solenoid assembly, camshaft timing gear bolt (camshaft timing oil control valve assembly [for exhaust camshaft]) and operating the camshaft timing exhaust gear; and 2) changing the relative positions of the camshaft and crankshaft.

MONITOR DESCRIPTION

To monitor the correlation of the exhaust camshaft position and crankshaft position, the ECM checks the VVT learned value while the engine is idling. The VVT learned value is calibrated based on the camshaft position and crankshaft position. The exhaust valve timing is set to the neutral position while the engine is idling. If the VVT learned value is out of the specified range in consecutive driving cycles, the ECM stores a DTC.
