SEF956N
SEF777Z
Component DescriptionNLEC1754The crankshaft position sensor (OBD) is located on the transaxle
housing facing the gear teeth (cogs) of the drive plate. It detects
the fluctuation of the engine revolution.
The sensor consists of a permanent magnet, core and coil.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
This sensor is not directly used to control the engine system. It is
used only for the on board diagnosis.
ECM Terminals and Reference ValueNLEC1755Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
