Engine Speed Sensor
Description
The engine speed sensor is installed on clutch case, against flywheel teeth. It is used to detect the speed and
position of crankshaft.
Operation
The engine speed sensor operates by using magnetoelectric effect. When crankshaft rotates, it drives
flywheel to rotate. The flywheel teeth will cut the magnetic line of sensor, and change of magnetic flux causes
both ends of sensor coil to generate output voltage with a certain frequency that is sent to Engine Control
Module (ECM). And the output signal can indicate the speed and position of crankshaft.
Removal
1. Turn off all electrical equipment and ignition switch.
2. Disconnect negative battery cable.
3. Remove engine trim cover.
