AXONE: ELECTRICAL ERRORS
Lambda probe P0130 - short circuit to positive.
Error cause
•
Excessive voltage (battery voltage) has been detected at PIN 43 of the ENGINE connector.
Caution: the "lambda probe" parameter is not the real value that is read; a recovery value
is displayed instead.
Troubleshooting
•
If shorted to positive: with key set to ON, disconnect the sensor connector and measure PIN
1 voltage on the cable harness side (grey cable): if there is voltage (5 or 12 V), restore the
cable harness; if there is not, replace the lambda probe.
Lambda probe heating P0135 - short circuit to positive / open circuit, short circuit to negative.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 32 of the ENGINE con-
nector.
•
If the circuit is open, short circuit to negative: voltage equal to zero has been detected at
PIN 32 of the ENGINE connector.
Troubleshooting
•
If shorted to positive: disconnect the probe connector and check the sensor correct resist-
ance: replace the sensor if not OK; if it is OK, restore the cable harness.
•
if the circuit is open, short circuit to negative: check the continuity from probe connector (PIN
3 and 4) towards the probe: if not OK, replace the probe; if it is correct, check the sensor
connector and the Marelli control unit connector. If not OK, restore. If OK, and with key set
to ON and sensor connector disconnected, check if there is battery voltage at PIN 4: if there
is not, check the red/black cable between the probe connector and the auxiliary injection
relay (No. 42 in the wiring diagram, located under fuel tank, right side, third relay starting
from the front; however, the identification of the relay with the colour of the cables). If there
are also coil and injector errors, check the relay and its excitation and power line; if there is
voltage at PIN 4, check the grey/blue cable earth insulation (PIN 3): if not OK, restore the
cable harness. If it is OK, check the continuity of the grey/blue cable (between the sensor
connector PIN 3 and the ENGINE PIN 32) and restore the cable harness.
AXONE: LOGIC ERRORS
Lambda probe P0134 - voltage without variation.
Error cause
•
An abnormal behaviour of the voltage at PIN 43 of the ENGINE connector has been detec-
ted: the voltage, that should vary over time, keeps a constant value instead.
