ELECTRICAL ERRORS
Front injector P0202 - shorted to positive / shorted to negative / open circuit.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 37 of connector A
(BROWN). 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 the key to KEY ON and activate
the component with Axone; check if there is voltage at PIN 2 of the injector connector: if
there is, restore the cable harness; if there is not, replace the sensor.
•
if shorted to negative: disconnect the injector connector, set the key to KEY ON and check
if there is a ground connection on PIN 2: if there is, restore; if there is not, replace the injector.
•
the circuit is open: 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 they are not OK, restore; if they are OK, check the continuity
of the cable between PIN 37 of connector A (BROWN) and PIN 2 of the component and
restore the cable harness.
Rear injector P0201 - shorted to positive / shorted to negative / open circuit.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 28 of connector A
(BROWN).
•
If shorted to negative: no voltage has been detected.
•
If the circuit is open: an interruption has been detected.
