Throttle body
Function
Sends to the injection control unit the throttle po-
sition 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
electrical diagnosis is possible for the throttle
body, but for the circuits connected to it only.
Level in electrical circuit diagram:
Throttle check and throttle grip sensor (Demand)
Location:
•
on the vehicle: inside the filter box
•
connector: 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 at idle: -0.5°
The system, reading the intake pressure, tries to balance the intake pressures between the front cylinder
and the rear one working on the throttle position: an acceptable value should be between -0.8º and
+0.8º.
Rear cylinder throttle correction
•
Example value with key ON: 0.0°
•
Example value with engine on: -0.3°
The system, reading the intake pressure, tries to balance the intake pressures between the front cylinder
and the rear one working on the throttle position: an acceptable value should be between -0.8º and
+0.8º.
