MONO BOSCH: composed of 2 sensors that work in parallel; it is to be found on MONO BOSCH injection systems.
TPS ADAPTER: If the engine has no TPS the control unit will emulate the position of the TPS on the basis of the
engine speed.
INDICATOR SENSOR TYPE
(fig. 18)
LANDI RENZO: select this parameter for all
LANDI RENZO sensors, both LPG and CNG.
AEB: if an AEB-type LPG sensor is used.
O-90W: for LPG indicator sensors that have an internal resistor of 0-90
Ω
.
LAMBDA SENSOR TYPE
(0-1V, 0-5V A, 0-5V B, 5-0V A, 5-0V B, 0.8-1.6V)
Tells the central unit what type of lambda sensor is mounted on the vehicle (fig. 19).
To know what type of sensor is on the vehicle it is necessary to measure the voltage on the wire of the lambda sensor
transmitting the signal to the computer; with the engine running, check in which range the voltage on this wire varies.
If the voltage varies between 0-1V or 0.8-1.6V, set the respective values.
If the voltage varies in a range between 0V and 5V it is necessary to make another measurement in order to identify
whether it is type A or B.
To measure the voltage on the lambda sensor wire, you need to cut the sensor wire and measure the voltage on
the wire reaching the vehicle’s original control unit with the panel switched on.
The sensor is type A if there is a voltage of 5V on this wire.
The sensor is type B if there is a voltage of 0V on this wire.
0-5V A, 5-0VA: The type A sensor indicates a lambda sensor that keeps the wire at a voltage of 5V when this
receives no signal.
0-5V B, 5-0V B: The type B sensor indicates a lambda sensor that keeps the wire at a voltage of 0V when this
receives no signal.
LAMBDA SENSOR READING DELAY
This is the time that passes from when the system comes into operation and starts reading the lambda sensor signal
(fig. 20).
This time allows the lambda sensor to warm up and to prevent the central unit from wrongly interpreting the signal
transmitted by the sensor.
The recommended method of identifying this time consists of starting the engine on petrol and measuring the time
the lambda sensor takes to transmit a signal with voltage within the working range.
Add 2 to 3 seconds to the measured time.
