MONITOR DESCRIPTION
The ECM checks valve timing (VVT learning value) on the exhaust side while the engine is running at a low speed, in order to monitor the gap
between the current and target valve timing on the exhaust side. The VVT learning value is calculated from the positions of the camshaft and
crankshaft. The camshaft will come to the most retarded position when the engine is running at a low speed. If the camshaft position is normal, the
VVT learning value should be within the specified range. If the VVT learning value is not within the specified range, the ECM determines this as a
malfunction.
