Engine coolant temperature sensor
This N.T.C. type sensor located on the water outlet sump on the engine head left measures coolant temperature for the various
operating logics with a hot or cold engine and identifies injection enrichment requirements for a cold engine or fuel reduction
requirements for a hot engine.
It is connected to electronic center pins 15/26.
Sensor behavior as a function of temperature:

This induction type sensor located on the camshaft generates signals obtained from the magnetic flow lines that close through the
6 plus 1 phase teeth of a sound wheel mounted on the shaft.
The electronic center uses the signal generated by this sensor as an injection step signal.
Though electrically identical to engine rpm sensor mounted in the camshaft in is NOT interchangeable with it as it cable is shorter
and it features a larger diameter.
This sensor’s air gap is NOT ADJUSTABLE.
