Description
NLEC0686
The crankshaft position sensor (TDC) monitors engine speed by
means of signals from the sensing plate (with three protrusions)
installed to the crankshaft pulley. The datum signal output is
detected at ATDC 10° and sent to the ECM. The sensor signal is
used for fuel injection control and fuel injection timing control.

ECM Terminals and Reference Value
NLEC0688
Specification 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.
