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:
-10°C8.10÷ 10.77 kOhm
+20°C2.28÷ 2.72 kOhm
+80°C0.29÷ 0.364 kOhm
At 60 to 90 _C, voltage at A5 and A22 ranges from 0.6 to 2.4V.
