•
Using the diagnostic tool, erase the error, then perform the throttle self-learning procedure.
If the error is displayed again, it may mean a mechanical problem at the throttle boy.
•
Check the cleanliness of the throttle body and the intake duct. Check if there are any me-
chanical ruptures. Replace the throttle body, if necessary.
DIAGNOSTIC TOOL: ADJUSTABLE PARAMETERS
Throttle self-learning.
NOTE
AT EVERY "KEY ON", THE CONTROL UNIT PERFORMS A TEST ON THE THROTTLE VALVES
TO CHECK THEIR MOBILITY, ASSESSING THE NECESSARY FORCE TO MOVE THEM AN THE
POTENTIAL PRESENCE OF OBSTACLES. AT EVERY 150 "KEY ON", THE SYSTEM PERFORMS
A STOPPER LEARNING FOR EACH THROTTLE BODY; IF START-UP IS ATTEMPTED DURING
THIS PROCEDURE (THAT REQUIRES APPROXIMATELY 3 SECONDS), THE ENGINE WILL NOT
START.
THROTTLE BODY RESET PROCEDURE
If a throttle body is replaced, or if it needs to perform automatic learning, proceed as follows:
After key ON, do not start the engine for the next 3 seconds, during which the throttle automatic learning
is performed by the control unit: according to the throttle body concerned, check that the "Front throttle
automatic self-learning" or the "Rear throttle automatic self-learning" status indicates: "completed". If
the indication is not "completed", remove any errors that may exist on the vehicle and at the next key
On check that the statuses are "completed". Where appropriate, perform the throttle self-learning from
the "settings" screen and check that the "Throttle self-learning with diagnostics instrument" status in-
dicates: "completed" and that the "Front throttle automatic self-learning" or "Rear throttle automatic self-
learning" statuses indicate: "completed".
Engine oil pressure sensor
Function
Indicates the instrument panel if there is enough
oil pressure (0.5 +/-0.2 bar) in the engine.
Operation / Operating principle
Switch normally closed (control unit signal to
ground). The switch opens at pressure values
above 0.5 ± 0.2 bar.
Level in electrical circuit diagram:
