•
Disconnect the sensor connector.
•
Check the sensor connector PIN 2 ground insulation.
•
If there is no ground insulation restore the cabling.
•
If PIN 2 is insulated from the ground and the error persists, this means that there is a probable
fault in the control unit.
Lambda sensor
(V7 SPECIAL / V7 STONE / V7 RACER)
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.
