Component description
English
For the purpose of carburetion adjustments, the Oxygen Sensor provides information to the
COMPUTER about the quantity of oxygen existing in the exhaust gases. If a high level of
oxygen is present in the exhaust, the carburetion is LEAN (small amount of fuel). If a low
level of oxygen is present in the exhaust, the carburetion is RICH (large amount of fuel).
To sort out the signal carrier wire of an Oxygen Sensor, we recommend using a digital
multimeter. Set the instrument to measure DC; put a probe to battery GROUND; with the
other probe check which wire carries a variable voltage. It is important that the Oxygen
Sensor is hot before performing this test.

The stepper motor has the function of modulating the flow of the GAS taken in by the
engine. It maintains optimal values of carburetion in any operational condition. To that end,
the “
GALILEO
” processes the THROTTLE POSITION SENSOR, OXYGEN SENSOR and RPM
SIGNALS.
