AXONE: PARAMETERS
Lambda probe
Example value: 0 - 1000 mV
If there is a short circuit at + 5 V or above, the value read is approx. 5.000 mV. If there is a short circuit
to ground instead, the value read is equal to 0 mV and the Lambda Sensor Correction parameter shows
25%: no error is displayed, though.
Lambda sensor correction
Example value: 1.00
In closed loop, the value must be close to 0 % (values not within the +10 % and -10 % range may
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%.
AXONE: STATUSES
Lambda check
Example value:
Open loop / Closed loop
Closed loop indicates that the control unit is using the lambda probe signal to keep the combustion as
close as possible to the stoichiometric value.
AXONE: ELECTRICAL ERRORS
Lambda probe P0130
- shorted to positive.
Error cause
•
Excessive voltage (battery voltage) has been detected at PINS 32 and 22 of the BLUE
connector.
Troubleshooting
•
if shorted to positive: with the key set to ON, disconnect the sensor connector and measure
voltage at PIN 1 on the cable harness side (white/yellow cable): if there is voltage (5 or 12
V), restore the cable harness; it there is no voltage, measure voltage at PIN 2, cable harness
side, (green/white cable) and if there is voltage, restore the cable harness; if there is no
voltage, replace the lambda probe
Lambda probe heating P0135 -
shorted to positive / open circuit, shorted to negative.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 11 of the BLUE connector.
•
If the circuit is open, shorted to negative: voltage equal to zero has been detected at PIN 11
of the BLUE connector
