ENGINE TEMPERATURE SENSOR
The engine sensor T is an NTC type (negative temperature coefficient); its internal
resistance will decrease with the increasing of the temperature.
It is checked with an ohmmeter connected to the sensor terminals or even better with a
voltmeter, during the engine running The voltage of the cold engine should be
U = 5 V
;
this voltage decreases according to the heating of the engine. In case there is a short circuit
the voltage will drop, first slowly, then suddenly. This is a very precise diagnosis as it is
done under running.
The engine sensor T is not to be repaired but replaced.
