2GR-FE ENGINE CONTROL SYSTEM
– SFI SYSTEM
ES
Reference: Inspection using an oscilloscope
HINT:
•
The correct waveform is as shown.
•
EV1+ and EV2+ stand for the VVT sensor signal, and NE+ stands for the CKP 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.
