•
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 53 and
component PIN 2 and restore the cable harness.
Internal rear cylinder injector P0206
•
short circuit to positive/ short circuit to negative / open circuit
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 67. 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 white/black 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 White/Black 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 67 and
component PIN 2 and restore the cable harness.
Fuel pump
Function
Fuel pump: keeps pressure of the injectors supply
duct.
Low fuel: tells to the instrument panel about low
fuel
Operation / Operating principle
Low fuel: it is a resistance that if correctly supplied
varies its electrical resistance if it is damped or not
by petrol.
Level in electrical circuit diagram:
Injection load relay
Location:
•
on the vehicle: on the tank.
•
connector: near the fuel pump (4 ways,
black).
