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 electrical circuit diagram:Lambda
probe
Location:
•
on the vehicle: exhaust pipe
•
connector: over the clutch side housing
Electrical characteristics:
•
Oxygen probe with preheating circuit
(power 7W)
•
It generates voltage within: 0 - 1000
mV
•
Heater circuit: continuity (7 - 9 Ohm at
ambient temperature)
Pin-out:
1. Sensor signal + (black wire)
2. Sensor signal - (grey wire)
3. Heater ground connection (white)
4. Heater power supply (white)
THE CONNECTION DIAGRAMS ARE IN THE ELECTRICAL SYSTEM SECTIONS; PAY ATTENTION
TO THESE DIAGRAMS AS THEY SHOW THE CONNECTOR/COMPONENT AS VIEWED FROM
THE CABLE HARNESS SIDE, THAT IS LOOKING AT THE CABLES WHEN GOING OUT OF THE
"MAIN" CABLE HARNESS AND INTO THE CONNECTOR/COMPONENT.
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL TROU-
BLESHOOTING CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGINNING OF THE CHECK
AND CONTROL SECTION IN THE ELECTRICAL SYSTEM CHAPTER.
NAVIGATOR: PARAMETERS
Lambda probe
example value: 0 - 1000 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.
Lambda sensor correction
example value: 1.00
In closed loop, the value must be close to 1.00 (values not within the 0.90 - 1.10 interval indicate a fault):
for example, value 0.75 corresponds to +25% with respect to the reference injection time; 1.25 corre-
