The continuity of the wiring is necessary for correct activation: no error indications are displayed in case
of lack of activation.
NAVIGATOR: ELECTRICAL ERRORS
Front cylinder injector P0201
- shorted to positive / shorted to negative / open circuit.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 50 of the ENGINE con-
nector.
•
If shorted to negative: no voltage has been detected.
•
If the circuit is open: an interruption has been detected.
Troubleshooting
•
shorted to positive: disconnect the injector connector, set key to ON, activate the component
with Navigator and check the voltage on the grey/green cable on the filter box small con-
nector towards the Marelli control unit: 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 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/green 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 ENGINE PIN 50 and component PIN - and restore the cable harness.

Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 34 of the ENGINE con-
nector.
•
If shorted to negative: no voltage has been detected.
•
If the circuit is open: an interruption has been detected.
Troubleshooting
•
shorted to positive: disconnect the injector connector, set key to ON, activate the component
with Navigator and check the voltage on the grey/green cable on the filter box small con-
nector towards the Marelli control unit: 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
