Camshaft Position Sensor
The camshaft position sensor uses hall-effect to set the camshaft position and metallic-magnetic-material sensor end is
attached on the camshaft and then rotates with it. If sensor protrusion passes camshaft position sensor’s semi-conduc-
tor wafer, magnetic field changes direction of electron on the semi-conductor wafer to the current flow direction that
passes through wafer from the right angle. When operation power is supplied from camshaft position sensor, camshaft
hall sensor generates signal voltage. The signal voltage will be 0V if protrusion and camshaft position sensor are near
and 5 V if apart.
ECU can recognize that the No. 1 cylinder is under compression stroke by using this voltage signal (hall voltage).
The rotating speed of camshaft is half of the crankshaft and controls engine’s intake and exhaust valves. By installing
sensor on the camshaft, can recognize specific cylinder’s status, compression stroke or exhaust stroke, by using
camshaft position when the piston is moving toward TDC (OT). Especially when started first, it is difficult to calculate the
stroke of a specific cylinder with only crankshaft position sensor.
Accordingly, camshaft position sensor is necessary to identify the cylinders correctly during initial starting. However,
when engine is started, ECU learns every cylinder of the engine with crankshaft position sensor signals so can run the
engine even though the camshaft position sensor is defective during engine running.
