- Reference: Inspection using an oscilloscope
HINT
- The correct waveform is as shown.
- VV1+ and VV2+ stand for the VVT sensor signal, and NE+ stands for the crankshaft position sensor signal.
MONITOR DESCRIPTION
If no signal is transmitted by the VVT sensor despite the engine revolving, or the rotations of the camshaft and the crankshaft are not synchronized,
the ECM interprets this as a malfunction of the sensor.
