Make sure that the throttle valve control is in con-
tact with the stop screw.
Guaranteeing that this position will be kept, give the confirmation for the TPS reset procedure.
Reset should be performed in the following cases:
- on first fitting.
- if the injection control unit is replaced.
NOTE
THE TPS RESETTING PROCEDURE MUST NOT BE CARRIED OUT WITH A USED THROTTLE
BODY BECAUSE POSSIBLE VALVE WEAR AND STOP WEAR FOR THE MINIMUM OPENING
MAKE THE AIR FLOW DIFFERENT FROM THAT OF THE PRE-CALIBRATION.
Given that the TPS reset is also carried out when
the control unit is replaced, place the control unit -
filter box bellows fixing clip at 45° upon refitting as
shown in the photograph.
Lambda probe
The lambda probe or oxygen sensor is a sensor which provides information about the oxygen content
in the exhaust fumes. The signal generated is not of the proportional but of the ON/OFF type, i.e. whether
there is oxygen or not. The probe is positioned on the exhaust manifold before the catalytic converter
in an area where the gas temperature is always high. The temperature at which the probe works is at
least 350°C at 600°C and it has a reaction time of just 50 milliseconds. The signal generated passes
from a high value to a low one with a mixture with lambda =1.
