Throttle Position Sensor - MOTO GUZZI Griso1200 8V Service Station Manual

GRISO 8V - 1200
if there is not continuity, restore the cable harness; if there is continuity, check the interruption on the
sensor and replace it.
WARNING If the electric circuit is short-circuited, no error is displayed. Check the sensor electrical
specifications: If they are not correct, replace the sensor. If correct, check supply insulation and ground
connection insulation of both cables. Perform the tests from the sensor connector towards the sensor.
If they are not OK, restore the cable harness or replace the sensor. If OK, perform the tests for pins 25
and 35 of the Marelli control unit connector A (BROWN) towards the cable harness.
Air gap value:
Place the sensor plus the corresponding spacers; the air gap should be between 0.7 and 0.9 mm.

Throttle position sensor

A: ground connection
B: supply voltage +5V
C: potentiometer signal
THE CONNECTION DIAGRAMS ARE IN THE ELECTRICAL SYSTEM SECTIONS; PAY ATTENTION
TO THESE DIAGRAMS AS THEY SHOW THE CONNECTOR/COMPONENT AS VIEWED FROM
THE CABLE HARNESS SIDE, THAT IS LOOKING AT THE CABLES WHEN GOING OUT OF THE
"MAIN" CABLE HARNESS AND INTO THE CONNECTOR/COMPONENT.
