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)
DIAGNOSTIC TOOL:PARAMETERS
Lambda probe
•
Example value with key ON: about 3300 mV
•
Example value with engine on: 100-1000 mV
If there is a short circuit at + 5 V or higher, the lambda probe parameter is not equal to the value read
by the control unit, but a recovery value is displayed
Lambda correction
•
Example value with key ON: 0 %
•
Example value with engine on: -10% / +10%
In closed loop, the value must be close to 1.00 (values not within the -15% / +15% interval indicate a
fault). In an open circuit, the lambda probe signal is too low. Therefore, the control unit takes it as a lean
mixture condition and will try to enrich it. The value read will be +25%: once this value is reached and
kept unchanged for a certain time, the function diagnosis of the lambda probe is activated with following
deactivation of it.
This diagnosis is activated when the correction constantly arrives -25%.
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.
DIAGNOSTIC TOOL: STATUSES
Lambda probe: Start-up_Lean_Rich_Fault due to rich titre_Fault due to lean air-fuel mixture
•
If the probe connector is disconnected (voltage almost equal to zero) it switches to the state
of Fault due to lean air-fuel mixture
Lambda check: Open loop/Closed loop/Rich in closed loop/Lean in closed loop/enriched
•
Closed loop indicates that the control unit is using the lambda probe signal to keep the
combustion is close as possible to the stoichiometric value.
DIAGNOSTIC TOOL: ACTIVATIONS
Lambda probe heater
•
The injection relay (No. 17 in the electrical circuit diagram, placed under the left side tank,
CHECK, however, the identification of the relay with the colour of the cables) is energised
and the heating circuit is closed to ground 5 times (Pin 3 of the Lambda probe connector).
