CAPONORD 1200
in order to work properly, it should reach a high operating temperature: that is why there is a heating
circuit inside.
Level in electrical circuit diagram:
Lambda probe
FRONT CYLINDER LAMBDA PROBE
Location:
•
on the vehicle: exhaust end behind the
rear head
•
connector: on the right side, at the back
of the filter box
Electrical specifications
•
Heater circuit: 7-9Ω at Ambient temp.

REAR CYLINDER LAMBDA PROBE
Location:
•
on the vehicle: exhaust end behind the
rear head
•
connector: on the right side, at the back
of the filter box
Electrical specifications
•
Heater circuit: 7-9Ω at Ambient temp.
Pin out:

DIAGNOSTICS 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 displayed instead.
