Throttle Position Sensor - MOTO GUZZI NORGE GT 8V Service Station Manual

Norge GT 8v
1. Engine revolution sensor positive signal.
2. Engine revolution sensor negative signal.
3. Revolution sensor anti-jamming cable.
NAVIGATOR: PARAMETERS
Target engine revs
Example value:1100 +/- 100 rpm
Parameter valid at idle, setting depends especially on engine temperature: the ECU unit will try to keep
the engine running at this revs, acting on the ignition advance.
NAVIGATOR: STATUSES
Synchronisation
Example value:Synchronised / Not synchronised
Indicates if the control unit detects the revolution sensor signal correctly
DIAGNOSIS
Engine revolution sensor
An interruption in the sensor circuit has been detected, from PIN 25 to PIN 35 of connector A (BROWN)
Check the sensor connector and the injection control unit connector A (BROWN): it they are not OK,
restore. If OK, check continuity of the two cables leading to PINS 25 and 35 of the control unit connector:
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 (0.027
- 0.035 in).

Throttle position sensor

Function
In charge of telling the control unit the position of
the throttle valves.
Operation / Operating principle
