Throttle body
Function
Sends to the injection control unit the throttle position and activates the throttle according to the control
unit
Operation / Operating principle
All the unit internal components (potentiometer and electric motor) are contactless; therefore, no elec-
trical diagnosis is possible for the throttle body, but for the circuits connected to it only.
Level in wiring diagram:
Throttle check and throttle grip sensor (Demand)
Location:
•
on the vehicle: inside the filter box
•
connector: on the throttle body, in lower position, near the throttle motors
Pin out:
1. potentiometer signal 1
2. supply v 5V
3. throttle valve control (+)
4. potentiometer signal 2
5. throttle valve control (+)
6. ground connection
DIAGNOSIS INSTRUMENT:
PARAMETERS
Front cylinder throttle correction
•
Example value with key ON: 0.0°
•
Example value with engine on: 0.4°
The system, reading the intake pressure, tries to balance the intake pressures between the cylinders
of the rear bank (1-3) and of the front bank (2-4) working on the throttle position: an acceptable value
should be between -0.5 and + 0.5
Rear cylinder throttle correction
•
Example value with key ON: 0.0°
•
Example value with engine on: -0.2°
The system, reading the intake pressure, tries to balance the intake pressures between the cylinders
of the rear bank (1-3) and of the front bank (2-4) working on the throttle position: an acceptable value
should be between -0.5 and + 0.5
Front throttle Potentiometer 1 (degrees)
•
Example value with key ON: 7.8°
•
Example value with engine on: 1.4°
With key set to ON, the throttle is kept in position by the springs (around 5 -7°). After the engine starts
up at idle, the throttle is kept close to the mechanical minimum (above or equal to 0.5°). When the gear
