Camshaft Sensor(s)

ES300 is equipped with one camshaft sensor. The camshaft sensor contains a pick-up coil. A signal plate (rotor) is mounted on the camshaft. As the camshaft rotates, a protrusion on the signal plate passes near the pick-up coil. This induces AC voltage in the pick-up coil. The ECM senses AC voltage, and interprets it as camshaft position.
