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.
AXONE: FUEL INJECTION SYSTEM
PARAMETERS
Lambda probe
Example value: 0 - 1000 mV
Signal when energised that the control unit receives from the lambda probe: inversely proportional to
the presence of oxygen.
Lambda integrator
Example value: 0,00 %
In closed loop, the value must be close to 0.00 (values not within the interval from -10.0 % to 10.0 %
indicate a fault): for example, value 25% corresponds to +25% with respect to the reference injection
time; -25% corresponds to -25%. 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 correction has been tried, the value shifts to 0.00 fixed and the Lambda probe error is signalled.
STATUSES
Lambda
Example value:
Open loop / Closed loop
It indicates if the control unit is using (CLOSED) the lambda probe signal to keep the stoichiometric
combustion. At idle CLOSED only if: Air T >10° and engine T > 18° and engine running for at least 1-2
minutes.
ELECTRICAL ERRORS
Lambda probe P0130
- shorted to positive / open circuit, shorted to negative.
Error cause
•
If shorted to positive, excessive voltage has been detected at PIN 22 of connector B (BLUE).
If the circuit is open, shorted to negative, no voltage has been detected. In both cases, the
recovery function is hardly noticeable for the customer.
