- If the above tests provided a positive result, the injector should be replaced.

FUEL PUMP

Function

Pump fuel from the tank to introduce it in the in-

jection circuit.

Pin-out:

1. Not connected

2. Negative from control unit (injector activation)

3. Not connected

4. Not connected

5. Positive from control unit

ELECTRICAL ERRORS

Low fuel pump voltage P0231

- open circuit or short circuit to negative.

Error cause

Open circuit or short circuit to negative: interruption of the circuit or null voltage at PIN 2 of the pump

connector.

Troubleshooting

Open circuit:

- Perform the check of the fuel pump and control unit connectors.

- Check the continuity of the cable harness between the control unit connector and pump connector:

Control unit PIN 1 - pump PIN 2 and control unit PIN 9 - pump PIN 5. If there is no continuity, restore

the cable harness.

Short circuit to negative:

- Disconnect the control unit connector and the pump connector.

- Check the pump connector PIN 2 ground insulation (corresponding to control unit connector PIN 1).

If there is no insulation, restore the cable harness.

High fuel pump voltage P0232

- shorted to positive.

Error cause

Short circuit to positive: excessive voltage at PIN 1 of the control unit connector.

Troubleshooting

Short circuit to positive:

- Disconnect the control unit connector and the pump connector.

- Verify that there is no short to battery positive on pump connector PIN 2 (corresponding to control unit

connector PIN 1); if there is a short circuit, restore the cable harness.
