Electrical system
•
If shorted 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 there is connection, restore the cable
harness. If there is no connection, replace the injector.
•
If the circuit is open: 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 8 and
component PIN 2 and restore the cable harness.
External rear cylinder injector P0202
•
short circuit to positive/ short circuit to negative / open circuit
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 46. If shorted to negative:
no voltage has been detected. If the circuit is open: an interruption has been detected.
Troubleshooting
•
If shorted to positive: disconnect the injector connector, set key to ON, activate the compo-
nent with the diagnosis instrument and check the voltage on the orange/white cable on the
injector connector. If following the activation the voltage does not drop, restore the cabling,
otherwise replace the injector.
•
If shorted to negative: disconnect the injector connector, set the key to ON and check if there
is a ground connection on the orange/white cable: if there is connection, restore the cable
harness. If there is no connection, replace the injector.
•
If the circuit is open: 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 2 and restore the cable harness.
Internal front cylinder injector P0205
•
short circuit to positive/ short circuit to negative / open circuit
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 53. If shorted to negative:
no voltage has been detected. If the circuit is open: an interruption has been detected.
Troubleshooting
•
If shorted to positive: disconnect the injector connector, set key to ON, activate the compo-
nent with the diagnosis instrument and check the voltage on the grey/red cable on the
injector connector. If following the activation the voltage does not drop, restore the cabling,
otherwise replace the injector.
•
If 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 connection, restore the cable har-
ness. If there is no connection, replace the injector.
