REGULATOR OF IDLE RUNNING
This regulator ( drawing 1, position 9 ) is used to position the valve in order to obtain
the idle rotation. It is mounted into a case together with a switch. The idle running is
realized at the moment of switch contact closing (
position 4 ), being necessary to the
normal idle functioning or to the engine brake.
The computer sends an electric signal to the regulator through the pins 32 and 34 . The
regulator will position the valve in order to obtain the idle rotation ( 800 ± 50 rot/min ).
Components:
1 - Electric motor step by step
2 - Endless screw
3 - Endless screwed wheel
4 - Switch
5 - Protection buffer
The switch connector and the idle motion actuator consist of:
1, 2 - Actuator supply
( pin 32, pin 34 computer ).
3 - Idle motion switch
( pin 8 computer ).
4 - Mass
By connecting an ohmmeter to the
connector wires 3 and 4, one can see that
the switch positions:
- CLOSE – functioning status,
continuity
- OPEN – stand-by status, R =
Reference values measured at the
connected wires:
R

= 0 – 200 Ù – contact close
R
