Crank Angle Sensor (CAS)
The crank angle sensor is installed on the sensor
case and houses an element which converts mag-
netic changes into voltage.
Magnetic changes produced by the rotation of a
signal rotor installed on the camshaft are con-
verted into voltage signals by the element.
This voltage signal is sent to the ECM, where it
becomes a basic signal for distinguishing cylin-
ders and for determining engine rpm.
Vehicle Speed Sensor (SPD)
The vehicle speed sensor is installed on the trans-
mission and is a sensor which converts magnetic
changes produced by the rotation of the signal
rotor into voltage signals.
The vehicle speed sensor performs frequency
division so that 4 pulses are output for 1 signal
rotor rotation, and the output is connected to the
speedometer, ECM and speed limit module.
