Bank angle sensor
Function
it tells the vehicle position to the control unit.
Operation / Operating principle
When the sensor is inverted, the circuit is closed
to ground: when the Marelli control unit detects this
ground, it deactivates the circuit of the fuel pump
and the engine start-up circuit, via the injection re-
lay.
Level in wiring diagram: Start-up enabling
switches.
Location:
•
under the saddle, rear section
•
connector: near the sensor
Electrical characteristics:
•
Sensor in vertical position: open circuit
(resistance: 62 kOhm)
•
Sensor inverted: closed circuit (resist-
ance lower than 0.5 kOhm)
Pin-out:
•
Pink/yellow (cable harness side): Volt-
age 12V
•
Grey (cable harness side): ground con-
nection
DIAGNOSIS
The vehicle starts, even if the sensor is inverted: disconnect the connector and, with sensor inverted,
check if there is continuity between the two PINS of the sensor: if there is not continuity, replace the
sensor; if there is, check the connector. If it is not OK, restore the cable harness; if it is OK, check ground
connection continuity of the PIN marked by the grey cable on the cable harness side: if there is no
continuity, restore the cable harness; if there is, with key set to ON, check if there is 12V voltage at the
PIN marked by the red/yellow cable on the cable harness side. If there is not, check the PIN 16 of the
Marelli control unit connector.
The vehicle does not start with the sensor in vertical position: disconnect the connector and check if
there is continuity between the two PINS when the sensor is in vertical position: if there is continuity,
replace the sensor; if there is not continuity, it means that, with key set to ON, there is not 12V voltage
