Variable Valve Timing Sensor (ES300, GS400, LS400, RX300 & SC400)
NOTE:
GS300 and SC300 models are equipped with variable valve timing but use the camshaft position sensor instead of Variable Valve Timing (VVT) sensors to determine camshaft position. See CAMSHAFT POSITION SENSOR . On ES300 and RX300, VVT sensor may also be referred to as camshaft position sensor.
The Variable Valve Timing (VVT) sensor consists of a signal plate and pick-up coil. The signal plate has one tooth and is mounted on each intake camshaft. When camshafts rotate, protrusion on the signal plate and the air gap on the pick-up coil changes causing fluctuations in the magnetic field and generates an electromotive force in the pick-up coil. The VVT sensor provides a feedback signal to ECM in order to control intake valve timing. See VARIABLE VALVE TIMING SENSOR LOCATION .
