Engine Temperature Sensor - MOTO GUZZI Stelvio 1200 NTX ABS Service Station Manual

Electrical system
Example value:open circuit, shorted to positive / shorted to negative.
Error cause
•
If the circuit is open, shorted to positive: excessive voltage has been detected at PIN 3 of
connector A (BROWN).
•
If shorted to negative: voltage equal to zero has been detected.
Troubleshooting
•
Circuit is open, shorted to positive: check the injection control unit connector and the sensor
connector: if they are not OK, restore; if they are OK, check continuity between PIN 3 of
connector A (BROWN) and PIN C of the sensor (red cable): if there is not continuity, restore
the cable harness; if there is continuity, check continuity of the sensor between PIN A and
PIN C: if there is not continuity, replace the potentiometer; if there is continuity, check the
resistance. If resistance is over 2.5 kOhm, it means the red cable is shorted to positive and
the cable harness should be restored
•
shorted to negative: disconnect the sensor connector and check the ground insulation of the
red cable (from throttle sensor connector or control unit connector): if there is continuity to
ground, restore the cable harness; if it is ground insulated, the resistance between PIN A
and PIN C is below 1.3 kOhm; therefore, the throttle body should be replaced
AXONE: ADJUSTABLE PARAMETERS
Throttle position autodetection: It allows the control unit to detect the closed throttle position; just
press the Enter key.
Self-adjustable parameters reset: Lambda probe self-adaptability parameters reset: operation to be
carried out after the throttle body is cleaned or in the case a new engine, a new lambda probe or a new
injector is fitted, or the correct operation of the injection system or the valves is restored.
AXONE: RESET PROCEDURE
Once the throttle body or the injection control unit is replaced, it is necessary to connect to the diagnosis
instrument selecting FUEL INJECTION and carry out the operation: Throttle positioner autodetection.

Engine temperature sensor

Function
tells the engine temperature to the control unit so
as to optimise its operation.
Operation / operating principle
NTC type sensor (resistance sensor, inversely
variable with temperature).
