Electrical system
connector and check if there is voltage at PIN -: if there is voltage, restore the filter box cable
harness. If there is no voltage, replace the sensor.
•
shorted to negative: disconnect the injector connector, set the key to ON and check if there
is a ground connection on the grey/red cable: if there is voltage, restore the cable harness
between the filter box connector and the Marelli control unit; if there is no voltage, reconnect
the connector and disconnect the injector connector and check if there is a ground connec-
tion on PIN -: if there is voltage, restore the filter box cable harness. If there is no voltage,
replace the injector.
•
the circuit is open: check the component correct electrical characteristic: if it is not correct,
replace the component; if it is correct, check the filter box small connector, the connector on
the component and the Marelli control unit connector: If not OK, restore. If OK, check cable
continuity between the ENGINE PIN 34 and component PIN - and restore the cable harness.
