The secondary injection relay (no. 35 in the electrical circuit diagram, placed under the fuel
tank, on the right side of the filter housing; CHECK, however, the identification of the relay
with the colour of the cables) is energised for 5 seconds and the injector cable connected
to the control unit is closed to ground for 4 ms per each second. It is recommended to
disconnect the 4-way connector of the fuel pump to be able to hear the relay and injector
activation. Electrical continuity is required in the wiring for the relay to activate correctly: no
errors are generated if the relay fails to activate
DIAGNOSTIC TOOL: ELECTRICAL ERRORS
P0201 Front cylinder injector
•
Short circuit to positive / short circuit to negative / open circuit
Error cause:
•
Short-circuit to positive: excessive voltage has been detected on VEHICLE PIN 53.
•
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, turn the key to ON, activate the
component with the diagnostic tool and check if there is voltage on the grey/red cable, on
the injector connector: if there is, restore the wiring harness of the filter housing; if not,
replace the sensor.
•
If short circuit to negative: disconnect the injector connector, turn the key to On and check
if there is ground connection in the cable grey/red: if the connection is present, restore the
wiring harness, if not present 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 the continuity of the cable be-
tween the VEHICLE PIN 53 and PIN 2 of the component and restore the wiring harness.
P0202 Rear cylinder injector
•
Short circuit to positive / short circuit to negative / open circuit
Error cause:
•
Short-circuit to positive: excessive voltage has been detected on VEHICLE PIN 67.
•
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, turn the key to ON, activate the
component with the diagnostic tool and check if there is voltage on the white/black cable,
