ENGINE IS STARTED, THE ACTIVATION IS NOT COMPLETED AND THE STOP LIGHTS DO NOT
TURN ON. EVERY 150 KEY-ONs, HOWEVER, THE THROTTLE VALVES ARE FORCED TO ACTI-
VATION. IF START-UP IS ATTEMPTED DURING THIS ACTIVATION (WHICH REQUIRES 3 SEC-
ONDS), THE ENGINE WILL NOT START.
FITTING: MECHANICAL/ELECTRICAL REFIT
RESET PROCEDURE
If a throttle body is replaced, after key is set to ON, do not start the engine within the 3 seconds; during
this time the control unit carries out the throttle self-acquisition process: according to the throttle body
replaced check that the status "Front throttle automatic self-acquisition" or "Rear throttle automatic self-
acquisition" indicates: "carried out". If indication is not "Carried out", delete possible errors on the vehicle
and then, with key set to ON, check that the statuses are "Carried out". If necessary, carry out "Throttle
self-acquisition" process on the adjustable parameters screen page (screwdriver and hammer), and
check again that the "Throttle self-acquisition with diagnosis instrument" status indicates: "Carried out"
and that the "Front throttle automatic self-acquisition" or "Rear throttle automatic self-acquisition" indi-
cate: "carried out"
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
Normally closed switch (grounds the control unit
signal); with pressure values above 0.5 ± 0.2 bar,
the switch is tripped.
Level in wiring diagram:
Low fuel and oil pressure
Location:
•
on the vehicle: front side of the engine,
next to the oil filter.
•
connector: on the sensor.
Electrical specifications: -
Pin out:
1. Voltage: 5 V
