Lambda sensor
Function
In charge of telling the control unit whether the
mixture is lean or rich
Operation / operating principle
The Marelli injection control unit reads and inter-
prets a voltage generated by the difference in oxy-
gen content between the exhaust fumes and the
ambient. It does not require an external supply
source but, in order to work properly, it should
reach a high operating temperature: that is why
there is a heating circuit inside
Level in wiring diagram:
Lambda Probe
Location:
•
on the vehicle: left side of the vehicle
•
connector: on the right of the pinion
cover (4-ways black connector)
Electrical specifications
•
Heater circuit: 7-9
Ω
at Ambient temp.
Pin out:
1. Sensor (black wire)
2. Sensor signal - (grey wire)
3. Heater ground connection (white cable)
4. Heater power supply (white cable)
DIAGNOSIS INSTRUMENT:
PARAMETERS
Lambda probe
•
Example value with key ON: 0 mV
•
Example value with engine on:
100--900 mV
If there is a short circuit at + 5 V or above, the
lambda probe parameter is not equal to the value
read by the control unit; a recovery value is dis-
played instead
Lambda correction
•
Example value with key ON: 1,00 mV
