Introduction to the engine control system
on average between approximately 0.1 V and approximately 0.8 V). Note that the self-adaptive parameters should not
approach the upper and lower extremes of this range as this would indicate that the fuel-air mixture is too rich or too
lean.
The graph shows the typical pattern for the voltage generated by the oxygen sensor with the engine at idle speed and at
operating temperature. This voltage may be tested with an oscilloscope or even with a voltmeter, as it oscillates at low
frequency.
If none of the aforementioned tests identify the problem and the oxygen sensors are in proper working order, contact
Ducati.
Component replacement methods
No special measures are necessary in order to replace the oxygen sensors. After replacing one or both of the oxygen
sensors, reset the self-adaptive parameters relative to carburation with the DDS.
