DTC P1340 Camshaft Position Sensor "A" (Bank 1 Sensor 2): Description
WARNING: This page is about a different car, the 2007 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
The camshaft position sensor (G signal) consists of a magnet, iron core and pickup coil.
The camshaft drive gear (LH) has 3 teeth on its inner circumstance. When the camshaft gear rotates, air gap changes between the protrusion on the gear and the pickup coil. The change affects the magnetic field and results in changes in the resistance of the MRE element.
The crankshaft signal plate has 32 teeth and is mounted on the crankshaft. The crankshaft position sensor generates 32 signals at every engine revolution. The ECM detects the standard crankshaft angle based on the G signal and the actual crankshaft angle and the engine speed by the NE signal.
