•
If short circuit to negative: disconnect the injector connector, set the key to ON and check if
there is a ground connection on the white/green cable: if the connection is present, restore
the cable harness. If there is no connection, replace the injector
•
If open circuit: check the component correct electrical characteristic: if it is not the correct
one, replace the component; if it is correct, check the connector on the component and the
Marelli control unit connector: if not OK, restore. If OK, check cable continuity between the
ENGINE PIN 46 and component PIN - and restore the cable harness

short circuit to positive / short circuit to negative / open circuit
Error cause
•
Short-circuit to positive: excessive voltage has been detected on ENGINE PIN 45. If short
circuit to negative: no voltage has been detected. If open circuit: an interruption has been
detected
Troubleshooting
•
Short-circuit to positive: disconnect the injector connector, set key to ON, activate the com-
ponent with the diagnostic tool and check the voltage on the White/Blue cable on the injector
connector: if there is voltage, restore the filter box cable harness. If there is no voltage,
replace the sensor
