LX470 — NEW FEATURES 27 3) Camshaft Position Sensor The MRE (Magnetic Resistance Element) type camshaft position sensor converts changes in the magnetic field due to timing rotor rotation into internal circuit voltage. Unlike the pick-up type, an ON-OFF signal is output so that the sensor is not easily influenced by noise. This signal generates 3 pulses for every 2 revolutions of the crankshaft. Camshaft Position Sensor 720 ° Crank Angle 180 ° 60 ° 120 ° 180 ° 60 ° 120 ° 273GX77 The inspection method differs from the pick-up type because this sensor uses the MRE type. For details, see the 2006 LEXUS LX470 Repair Manual (Pub. No. RM0030U).
Service Tip 4) VVT Sensor A VVT sensor is mounted on the intake side of each cylinder head. To detect the camshaft position, a timing rotor that is provided on the intake camshaft is used to generate 3 pulses for every 2 revolutions of the crankshaft.
