INJECTOR
Function
Provide the correct amount of fuel at the correct
time.
Operation / Operating principle
Injector coil is excited for the petrol passage to
open.
Pinout:
1. Power from relay
2. Ground from control unit
ELECTRICAL ERRORS
Injector P0201
- shorted to positive / shorted to negative / open circuit.
Error cause
Shorted to positive: excessive voltage to PIN 34 of the control unit connector.
Shorted to negative: zero voltage to the PIN 1 of the injector connector.
Open circuit: circuit interruption.
Troubleshooting
Shorted to positive:
- Disconnect the injector connector, turn ignition switch to ON and activate the component using the
diagnostic tool.
- Verify the absence of voltage at the injector connector PIN 2; if present restore the cable harness,
otherwise proceed with the following checks.
Shorted to negative:
- Disconnect the injector connector, turn ignition switch to ON and activate the component using the
diagnostic tool.
- Verify the presence of voltage at the ends of the injector connector; if there is no voltage, restore the
cable harness, otherwise proceed with the following checks.
Open circuit:
- Perform the check of the injector and control unit connectors.
- Verify continuity of the cable harness between the control unit connector and the injector connector
(control unit PIN 34 - injector PIN 2). If there is no continuity, restore the cable harness.
FUEL PUMP
ELECTRICAL ERRORS
Fuel pump relay P0230
- shorted to positive / shorted to negative / open circuit.
Error cause
Shorted to positive: excessive voltage at PIN 22 of the control unit connector.
Short circuit to negative: null voltage at PIN 86 of the injection relay.
