AXONE: PARAMETERS
Throttle
Example value:
4.9°
AXONE: STATUSES
Throttle position
Example value:
Released/Pressed/Full load
It indicates if the throttle potentiometer is open or closed in the released position.
AXONE: ELECTRICAL ERRORS
Throttle actuator position sensor P0120
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
•
if 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 positioner 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.
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.
