Reset should be performed in the following cases:
- on first fitting.
- if the injection control unit is replaced.
N.B.
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 DIFFERENTLY FROM THAT OF PRE-CALIBRATION.
Given that the TPS resetting is also done when the
control unit is replaced, place the control unit - filter
box bellows at 45° during the refitting operation as
shown in the photograph.
Lambda probe
The Lambda sensor or oxygen sensor is a sensor which provides indications concerning the oxygen
content in the exhaust gas. The signal generated is not of the proportional type but of the ON/OFF type,
i.e. there is oxygen or there is not. The sensor 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 sensor
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 value with a mixture with lambda =1. Since the sensor only works at
high temperatures, it has an electric preheating element inside it, controlled by the control unit, to take
it quickly to the functioning state.
