O2 Sensor Type - A.E.B. AEB215 Manual De Uso

VEHICLE CONFIGURATION

O2 SENSOR TYPE

This indicates to the LEONARDO E.C.U. what type of Oxygen Sensor is present on the vehicle. Before
selecting the Oxygen Sensor type, it is necessary to check for proper operation of this unit by
using a digital multimeter. One of the probes of the multimeter must be put to ground at the
negative post of the battery. The other probe must be connected to the Oxygen Sensor's signal
carrier wire. The following page has information useful for determining the Oxygen Sensor
type.
0-1 V (Fig. 23)
Select this option if the voltage on the signal carrier wire toggles
between the following values:
- about 0÷0,2 V with lean mixture;
- about 0,8÷1 V with rich mixture.
0-5 V type A
This option refers to Oxygen Sensor types that are presently
not available. When these sensor types become available, this
manual will be updated with the appropriate instructions.
0-5 V type B (Fig. 24)
Select this option if the voltage on the signal carrier wire toggles
between the following values:
- about 0÷0,2 V with lean mixture;
- about 4,8÷5 V with rich mixture.
5-0 V type A (Fig. 25)
Select this option if the voltage on the signal carrier wire toggles
between the following values:
- about 4,8÷5 V with lean mixture;
- about 0÷0,2 V with rich mixture.
5-0 V type B
This option refers to Oxygen Sensor types that are presently
not available. When these sensor types become available, this
manual will be updated with the appropriate instructions.
0,8-1,6 V (Fig. 26)
Select this option if the voltage on the signal carrier wire toggles
between the following values:
- about 0,7÷0,8V with lean mixture;
- about 1,4÷1,6V with rich mixture.
