VV1 + and VV2+ stand for the VVT sensor signal, and NE+ stands for the CKP sensor signal.
WAVEFORM REFERENCE
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.
