Engine Rpm Sensor; Throttle Position Sensor; Engine Temperature Sensor - MOTO GUZZI GRISO 850 2007 Service Station Manual

Electrical system

Engine rpm sensor

Measures the engine revolution speed and each
cylinder timing in relation to the TDC
Inductive type sensor, with three-way connector:
•
positive voltage pin;
•
negative voltage pin: resistance from
650 to 720 Ohm (to be measured be-
tween pins 1 and 2);
•
shielding pin.
Air gap value: (measure sensor length with a depth
gauge): 0.5 - 0.7 mm (0.0197 - 0.0276 in).

Throttle position sensor

Output voltage 0.55 - 4.4 V (variable depending on
the position of the throttle valve, to be measured
between pins C and A)

Engine temperature sensor

This sensor, 5V powered, features NTC specifications and sends the control unit a signal which varies
depending on temperature to help manage the stoichiometric ratios during engine speed adjustment.
